Expiriments 9 through 11

Here's some exerts from my paper so far. I'm too lazy to edit them right now or to actually blog about the experiments. So here's expiriments 9 through 11

Experiment 9: Underwater Recording
For this experiment I developed 3 techniques for recording underwater.
Cover a dynamic mic with a condom
Cover a dynamic mic with a sandwich bag
Cover a dynamic mic with a plastic grocery bag
Cover a dynamic mic with plasti-dip
Use an actual hydrophone
Dry as recorded above water with a dynamic mic
In order to record, I had to overcome several challenges. How would I project sound underwater, and how do I keep the microphone’s dry? One of my dissertation committee members had experience with recording an electric guitar, I assumed since he hadn’t died of electrocution, he was successful. During my first committee meeting, I borrowed his hydrophone, and I finally had gotten around to this experiment. His advice for making underwater speakers was to take a midrange horn driver and cover it with a polyurethane coating. After doing some research and talking with a couple music store salesmen, I finally found a small audio components store that sold midrange horn drivers on the boarder of Gresham. What I didn’t realize when I got there were there were multiple types of midrange horn drivers. I went for the cheapest, smallest horn driver I could find due to my low budget and limited working space. Next I had to find polyurethane so I could coat the speaker. After a trip to A-boy, I realized I didn’t know what to buy, so I came home empty handed until I could research which product to buy. At first I was rather nervous about buying a can of Polyurethane coating because a can of it was in the price range of $40 to $50. This was getting my worried. After a while of searching, I found a product called Plasti-Dip which is used for coating the handles of tools. With a bit more research I found a site that had Plasti-Dipped a microphone in order to record underwater. I decided that this would be a good substitute for the polyurethane coating and took a short trip over to A-boy one more time. Luckly they had 3 cans left, I bought their last can of black plasti-dip and a 5’ length of audio cable to soldier to my speaker. Another step I had to take was learning how to soldier wires together which I found out is fairly simple. Next I applied the first coat on the speaker. This turned out well, but I found many tiny holes where air bubbles had popped and left the speaker exposed. Because I didn’t want the cone of the speaker to get covered too much, I took a pencil and liberally applied plasti-dip in the spots that had holes. Because it takes 4 hours to dry and I only have about 5 hours of free time a day, I was only able to apply a new layer once or twice a day. The process of waterproofing the speaker took about 4 days so that no part of the speaker had any exposure to the water. Once the speaker was done, I attached the wires to a stripped 1/4” wire to the audio wire that I had stripped and soldiered to the speaker. Unfortunately the speaker was 4ohms and the amp was an 8ohm amp, I believe this is why the speaker was giving me an ungodly 60hz hum. Next I tried hooking my speaker up to the banana jacks from my stereo’s amp to the exposed wires using gator clips. This removed the buzzing, but I couldn’t move my entire audio system from my living room down to the bathroom. My last ditch effort was hooking a modified stereo system I had borrowed from Random to the cables, success.
Now that I had my speakers out of the way, I had to figure out how to use the hydrophone that I borrowed. At first I was under the impression that the hydrophone had a single large wire protruding from it because it had been stripped and the end was tangled covering the fact it was a coaxial cable and was constructed of two different wires. Once that this was pointed out to me, I took the stripped 1/4” cable and soldiered alligator clips to the end of it, then clipped the ends of the clips to the raw wires of the hydrophone. Unfortunately I had wasted a day trying several different ways to attach the wire to my pre amp.
Before submerging my only $40 dynamic mic, I decided to go and buy the cheapest mic I could find so that if anything went wrong I wouldn’t lose a decent mic. Coincidentally my dad was going to frys that night so I hitched a ride and found the perfect karaoke mic for $10. Everything else fell into place, and I carried out my first tests. First thing I tested was covering the mic in a condom. Unfortunately the first one broke, so I used the second one which also broke. Rather than using the given rubber band at the end, I took a rubber band I found laying around which worked fine. In each test I held the mic partially submerged in 5” of water 1” away from the cone of the speaker. Nothing particularly exciting happened during the next couple tests. My last test was covering the mic in plasti-dip then submerging it. The only challenge I faced was that the holes in the grating over the mic bit kept popping holes when I dried the dip.
Track order by Number:
82. Dry
83. Condom
84. Sandwich Bag
85. Plasti-dip
86. Hydrophone

Experiment 10: Atmospheric Pressure by Depth
I had this idea if I recorded underwater with a hydrophone, the atmospheric pressure would play into the fact that the Piezo electrical device measures sounds by the pressure it displaces. So if there are various amounts of pressure being caused by the weight of the water, would this affect the overall sound of the recording? It appears that it does. Another reason for a change in sound may be a acoustical change due to new volume of the recording space, although I would have no way to determine this.
[Listen to tracks ______ through ______]
There is a difference between tracks 1 and 3 in sound, but the second track sounds very similar to track one although it has a higher intensity in reading the higher frequencies between 7000 and 8000kh range. I started at a depth of 5” and worked up from there to 7.5” and 10”. I recorded each depth twice one at 5” away from the cone of the speaker and once at 1” from the speaker.
I had the idea of putting a waterproofed dynamic mic underwater in order to compare the sound of a piezo based mic and a diaphragm mic, but after a bit of research, I realized that each mic just converts different pressures and that each mic is just acoustically tuned for the fluid it’s exposed to. Basically the only thing I would be getting out of a waterproofed mic is having the sound traveling through the water hitting the plastic rubber diaphragm then traveling through the trapped air. I went ahead and did it in experiment 9, the track is called Plasti-dip if you would like to compare
Track order by Number:
Track 87 : 5” of water
Track 88 : 7.5” of water
Track 89 : 10” of water
Experiment 11: Cones
For this experiment, I decided since I was testing things underwater, I may as well test how cones sound underwater as well. When I was building a underwater speaker out of a mid range driver, the speaker came with two cones attached a single cell loudspeaker cone and a small metal cone, these cones are supposed to be used in tandem in order to amplify the small speaker. I started getting curious if cones amplified underwater, which to me would be common sense, but I thought I would try it anyway. The final result was against my expectations. The cones were actually blocking the sound. I’m not sure why this was the final result, it’s exactly counter intuitive. The probable reason for this is I originally put the speaker 1” away from the hydrophone but with the cones I was setting the end of the cone 1” away from the hydrophone. I don’t think that this is the reason for the result is because I attached the horn to the speaker correctly, although I was holding the cone to the speaker and my hand may have muted the wave when I hit the initial chamber before leaving through the horn.
Track order by Number:
Track 90 No cone
Track 91 W/ horn only
Track 92 W/ metal only
Track 93 W/ both

Underwater Recording Try 1

So, I did my first underwater recording. I only did two tests. The first one was the frequency response, this wont be part of my dissertation. The next one was trying different cones on the speaker. The results were the cones muting the sound of the speaker. Anyway, everything sounds pretty normal - the dampening sound except the piano track which sounds like waving.

First test was a failure

So, I did my first test underwater. The speakers work great, the hydrophone however does not. The setup for the mic was a stripped 1/4" cable on the raw wire of the mic wire. I fed this into a pre amp. Unfortunately, this did not work. The plan now is I'm going to soldier the wire onto a 1/4" adapter on the right channel/mono ring.

Underwater Speaker

Yesterday, I was in the process of building a underwater mic. What I'm doing is taking a mid range driver (A type of speaker) soldiering on audio wires, then dipping the final product in plasti dip while making sure that no part is exposed to water. I did the first dip and it covered most of the speaker, unfortunately the dip missed a couple screw holes, so later today or tomorrow I'm going to cover the rest.

My first test is going to be in a bathtub. Some time this week I'm going to call up my local health club and see if I can use their swimming pool to test distance pickup ranges.

My in the bathtub tests, I'm also going to submerge most of a plastic bag with a speaker attached. This will test if a hydrophone can pick up any sounds when being transmitted from air to water. The third design is taking a plastic cone attached to a speaker being held out of the water. The sound will travel down the cone and vibrate the water, this will test if the sound outside of water can be recorded.

Ahhh, what a weekend.

Expiriment 4: Compression

Today I did a easy experiment. It's a very simple, and mainly for my own satisfaction and self education. I compressed the same sound file into 21 different formats just to see if there is a difference in the sound.

Yes, there is a difference.

for instance: a .dbl file sounds really nice, and in fact reduces the hissing I had in the original track... but everything is really speed up.

Tonight isn't the night for analysis, but there's allot of really cool sounds that came from this experiment and I'm really excited to share them

Kinda a crap day

Today was my first day recording with lightbulbs...

Here's a conversation I had with Random about recording with lightbulbs.
This really sums up what I did for the last 3 hours.

[5:28:05 PM] Kai Wolf Paquin: Hey random. How do I modify a boombox to power a lightbulb?
[5:28:29 PM | Edited 5:29:21 PM] Random Davis: well, you won't be able to power it through the headphone jack, as that's way too weak
[5:28:40 PM] Random Davis: you'll need to use actual cords meant for the speakers
[5:28:48 PM] Random Davis: like with your stereo system
[5:28:53 PM] Kai Wolf Paquin: Gotcha.
[5:28:58 PM] Random Davis: that would be very good with powering the bulbs
[5:29:03 PM] Kai Wolf Paquin: I'll get to work on that
[5:29:13 PM] Random Davis: an LED can be powered by a headphone jack easily
[5:29:31 PM] Kai Wolf Paquin: Should the lightbulb be making sounds?
[5:29:50 PM] Kai Wolf Paquin: Mine just did that when I connected it to the mic jack
[5:29:59 PM] Random Davis: headphone, not mic!
[5:30:08 PM] Kai Wolf Paquin: Sorry
[5:30:14 PM] Kai Wolf Paquin: Typed the wrong thing
[5:30:24 PM] Random Davis: if it's making noise, that's not a good thing usually
[5:30:38 PM] Kai Wolf Paquin: Yeah. It sounded like a tessala coil
[5:30:45 PM] Random Davis: buzzing?
[5:30:55 PM] Kai Wolf Paquin: yeah, It buzzed back the input
[5:31:03 PM] Random Davis: don't connect it to a computer
[5:31:20 PM] Random Davis: only to an actual boom box or a stereo system
[5:31:22 PM] Kai Wolf Paquin: No, I didn't.
[5:31:47 PM] Random Davis: and start the signal at a very weak level, then slowly add more power until the bulb actually gives light
[5:32:03 PM] Kai Wolf Paquin: I hooked it up to my amp via gator clips and a striped 1/4 inch cord. The lightbulb it'self was making that noise
[5:32:19 PM] Kai Wolf Paquin: Alright, that's good to know
[5:32:24 PM] Random Davis: bad idea hooking it up to the amp in my opinion
[5:32:32 PM] Random Davis: it gives a very strong signal
[5:32:41 PM] Random Davis: the stereo system would be much higher quality anyway
[5:32:49 PM] Kai Wolf Paquin: yeah, I figured that out fast. I used a very low signal though.
[5:32:52 PM | Edited 5:32:58 PM] Random Davis: and has built-in 2-wire outputs
[5:33:03 PM] Kai Wolf Paquin: I need to mod my boom box soon
[5:33:36 PM] Kai Wolf Paquin: I'm not going to use the sterio system because my parents would throw a fit
[5:34:12 PM] Random Davis: well, explain to them why it's safe
[5:34:25 PM] Random Davis: I'll write a little paragraph explaining why
[5:34:45 PM] Kai Wolf Paquin: theyre not here anyway
[5:35:18 PM] Random Davis: well, there's no way you could damage the stereo system unless you outputted power from the wires
[5:35:26 PM] Random Davis: don't connect the wires to a powered device
[5:35:33 PM] Kai Wolf Paquin: k
[5:35:37 PM] Random Davis: only to speakers with no power source
[5:35:48 PM] Random Davis: even shorting out the wires would do no harm
[5:35:49 PM] Kai Wolf Paquin: also, I need a dark room
[5:36:07 PM] Random Davis: and having a lot of resistance in the connection would create no harm
[5:36:08 PM] Kai Wolf Paquin: I would have to move the entire system
[5:36:18 PM] Random Davis: you don't need a dark room
[5:36:21 PM] Random Davis: just have the lights off
[5:36:37 PM] Random Davis: the sun will not give any noise unless it's directly shining on the CDS cell
[5:36:44 PM] Random Davis: just cast a shadow on the cell
[5:36:56 PM] Random Davis: or contain the bulb and cell within a cardboard box or something
[5:37:04 PM] Random Davis: it's not extremely sensitive
[5:38:03 PM] Kai Wolf Paquin: Oh cool, I didn't know that would work. One test I want to do though is once in a dark room and once in a light room
[5:39:38 PM] Kai Wolf Paquin: I'm just going to go for it
[5:43:32 PM] Kai Wolf Paquin: nothing
[5:45:33 PM] Kai Wolf Paquin: Sorry, my internet went down
[5:50:59 PM] Kai Wolf Paquin: ...
[5:51:32 PM] Random Davis: what did you mean by "nothing"?
[5:51:37 PM] Kai Wolf Paquin: no light
[5:52:07 PM] Random Davis: do you know if the bulb even still works after you potentially destroyed it by connecting it to the amp?
[5:52:19 PM] Kai Wolf Paquin: I dont
[5:52:34 PM] Random Davis: was it the bulb I gave you?
[5:52:58 PM] Kai Wolf Paquin: I think I ruined it, and I'll definately replace the bulb ofcourse
[5:53:07 PM] Kai Wolf Paquin: yeah
[5:53:19 PM] Random Davis: you don't have to. they're only like a dollar each. and I had no use for that one anyway
[5:53:31 PM] Random Davis: but try connecting a battery to it, pr putting it in a flashlight
[5:53:40 PM] Kai Wolf Paquin: k one minute
[5:55:11 PM] Kai Wolf Paquin: yeah. Destroyed
[5:55:24 PM] Random Davis: well, make sure the wires are connected properly
[5:55:33 PM] Random Davis: re-tape the wires to it if necessary
[5:56:14 PM] Kai Wolf Paquin: I did. I tried both to both sides, and pressed the wires against the base of the bulb which was working earlier.
[5:56:34 PM] Kai Wolf Paquin: Would a house hold bulb work, or do I need a small bulb?
[5:56:49 PM] Random Davis: a household bulb requires 120volts AC power
[5:57:03 PM] Kai Wolf Paquin: Yeah, I know
[5:57:03 PM] Random Davis: there's no way you could connect a stereo to it and get any sound form it
[5:57:13 PM] Kai Wolf Paquin: I thought so
[5:57:30 PM] Random Davis: you need flashlight bulbs, something that will work on a relatively low DC voltage
[5:57:47 PM] Kai Wolf Paquin: I have some old flashlights I could find some bulbs from
[5:57:57 PM] Random Davis: yeah, that would work
[5:59:47 PM] Kai Wolf Paquin: yeah, working on that now
[6:00:53 PM] Kai Wolf Paquin: so one cord should be attached to the saudering and one to the bottom?
[6:01:27 PM] Random Davis: one cord on the very bottom, the other on the side.
[6:01:43 PM] Random Davis: it would be better to keep it in its housing
[6:02:31 PM] Random Davis: and make sure that the stereo system is outputting at all, just in case it doesn't work when connecting it to the bulb.
[6:02:40 PM] Random Davis: have one spreaker still be connected, maybe
[6:03:32 PM] Kai Wolf Paquin: k
[6:10:00 PM] Kai Wolf Paquin: No, not working
[6:10:16 PM] Random Davis: check to make sure hte bulb is in working order
[6:10:22 PM] Kai Wolf Paquin: k
[6:12:13 PM] Kai Wolf Paquin: yeah, it works. I think the problem was it wasn't attached by the tape very well
[6:12:38 PM] Random Davis: hold the wires with your fingers]
[6:12:57 PM] Random Davis: but try it in its housing, which willl be much easier to connect the wires to
[6:13:21 PM] Kai Wolf Paquin: I can't get the housing out of the flashlight
[6:13:51 PM] Random Davis: no, keep it in the flashlight
[6:14:03 PM] Random Davis: connect the wires to where the batteries normally connect
[6:14:15 PM] Random Davis: but some flashlights may not work when the bottom is removed
[6:14:24 PM] Kai Wolf Paquin: oh, duh, that seems really simple
[6:14:26 PM] Random Davis: or the shaft may be too long for you to put the wire in
[6:15:25 PM] Kai Wolf Paquin: yep
[6:27:34 PM] Kai Wolf Paquin: Got it to work
[6:27:41 PM] Random Davis: cool
[6:27:49 PM] Random Davis: wires just needed to be connected properly?
[6:28:27 PM] Kai Wolf Paquin: yeah. I ended up hooking them to gator clips then holing the other side to the bulb
[6:29:09 PM] Random Davis: So, are you getting an audio signal?
[6:29:55 PM] Kai Wolf Paquin: No, I still need to buy batteries for the board. I'm going to the store right now to get some
[6:30:06 PM] Kai Wolf Paquin: Otherwise I'm good to go
[6:30:08 PM] Random Davis: I told yoy, you don't need batteries
[6:30:18 PM] Random Davis: you just need to connect two wires to the CDS cell
[6:30:45 PM] Kai Wolf Paquin: oh, I haven't tried yet, I just assumed I needed batteries since there
[6:30:57 PM] Kai Wolf Paquin: s a giant battery pack on it
[6:31:11 PM] Kai Wolf Paquin: K, well I'm testing it out now then
[6:31:29 PM] Random Davis: I told you that yesterday
[6:31:31 PM] Random Davis: er, sunday
[6:31:46 PM] Random Davis: you're connecting directly to the CDS cell witht he springs
[6:31:50 PM] Random Davis: it doesn't need power
[6:32:59 PM] Kai Wolf Paquin: Cool, sorry. I forgot everything you said on sunday
[6:33:31 PM] Random Davis: lol
[6:33:32 PM] Kai Wolf Paquin: Alright, I need to burn a CD of my tracks first then I'm good to go
[6:33:40 PM] Random Davis: cool
[6:33:58 PM] Random Davis: and don't connect my CDS cell to your amp
[6:34:05 PM] Random Davis: connect it to the mic port on your computer
[6:35:37 PM] Kai Wolf Paquin: Lol, yeah, I know
[7:00:21 PM] Kai Wolf Paquin: For no apparent reason, my sterio system broke
[7:00:56 PM] Kai Wolf Paquin: Even the side that I didn't unplug won't play loudly. I find this to be stupid
[7:03:32 PM] Kai Wolf Paquin: NM, there was something wrong with the sterio amp, it fixed it's self
[7:34:46 PM] Kai Wolf Paquin: So I'm done now. I have really different results than you do
[7:34:52 PM] Kai Wolf Paquin: wanna hear?
[7:34:58 PM] Random Davis: sure
Kai Wolf Paquin
[7:35:56 PM] Kai Wolf Paquin: I get more beeping than sounds
[7:37:22 PM] Kai Wolf Paquin: what do you think?
[7:37:35 PM] Random Davis: try using your tape recorder
[7:37:58 PM] Random Davis: connect the CDS cell to the tape recorder's mic jack (not aux jack), then output the tape recorder to the PC directly
[7:38:15 PM] Random Davis: don't record to a tape - just feed the direct output
[7:38:28 PM] Random Davis: also, it apepared that the bulb was rather dim
[7:38:28 PM] Kai Wolf Paquin: I think I figured out the problem. I recorded in sterio, but I just realized I was using a mono jack
[7:38:41 PM] Random Davis: but use the tape recorder
[7:38:46 PM] Random Davis: you'll ger much better results
[7:38:51 PM] Kai Wolf Paquin: If my idea fails, I'll try yours
[7:40:52 PM | Edited 7:40:57 PM] Random Davis: you're getting a DC level, but very little variance in that DC
[7:42:04 PM] Kai Wolf Paquin: huh, really? I'm going to record through my tape player. I might need help setting it up though
[7:42:33 PM | Edited 7:43:10 PM] Random Davis: use a double-male-ended cable that feeds to your computer's line-in port
[7:43:02 PM] Random Davis: and connect the CdS cell to the mic port of the tape recorder just like you did for your laptop's mic port
[7:43:51 PM] Kai Wolf Paquin: I trick it to run without tape too right?
[7:43:57 PM] Random Davis: yeah
[7:44:21 PM] Random Davis: but it would be easier to put a tape in, press the pause button, then the record button
[7:44:34 PM] Kai Wolf Paquin: K that's good too
[7:48:46 PM] Kai Wolf Paquin: I'm getting a ton of electrical feed back. I'm using a DC current, should I be using an AC current?
[7:49:09 PM] Random Davis: what do you mean by electrical feedback? a loud 60hz tone?
[7:49:43 PM] Kai Wolf Paquin: no a huge buzzing sound. It sounds like when you plug a 1/4 inch cable half way in
[7:50:06 PM] Random Davis: even with the tape recorder off?
[7:50:44 PM] Kai Wolf Paquin: no, just when on. I think it may have been due to volume. I just saw it was all the way up. I'll try in when it's down
[7:51:00 PM] Random Davis: it may be amplifying an idle current
[7:51:14 PM] Kai Wolf Paquin: nah, still there
[7:51:21 PM] Random Davis: connect the CDS cell, then flicker the lighbulb
[7:51:25 PM] Random Davis: with music
[7:51:30 PM] Kai Wolf Paquin: k will do
[7:52:09 PM] Random Davis: also, unplug the laptop from the wall and just use battery power
[7:52:20 PM] Random Davis: it will unground the connection, reducing the buzzing
[7:52:38 PM] Kai Wolf Paquin: it is
[7:52:56 PM] Random Davis: ok
[7:53:43 PM] Kai Wolf Paquin: here
[7:53:51 PM] Kai Wolf Paquin: s a copy
Kai Wolf Paquin
[7:55:05 PM] Kai Wolf Paquin: I'll try AC
[7:55:18 PM] Random Davis: no, that won't make a difference
[7:55:30 PM] Random Davis: unplug it frmo the computer, and plug headphones directly into the tape recorder
[7:55:33 PM] Random Davis: tell me what you hear
[7:56:58 PM] Random Davis: and it sounds like you're just receiving electrical feedback, not actual light vatiations
[7:56:59 PM] Kai Wolf Paquin: k
[7:57:58 PM] Kai Wolf Paquin: same except better quality
[7:58:09 PM] Random Davis: so, lots of humming?
[7:58:18 PM] Kai Wolf Paquin: yeah
[7:58:31 PM] Random Davis: try reversing the wires connected to the CDS cell
[7:58:52 PM] Kai Wolf Paquin: Sure
[7:59:26 PM] Kai Wolf Paquin: Wait, I think I got it
[8:00:42 PM] Kai Wolf Paquin: If I push the button halfway down it's fine. Also, the play button goes down at the same time when I record. I think that's why I'm having this problem
[8:00:49 PM] Kai Wolf Paquin: Any solution?
[8:01:15 PM] Kai Wolf Paquin: brb
[8:02:06 PM] Random Davis: the play button going down at the same time is normal. Make sure the tape player is paused when doing this, too
[8:02:12 PM] Kai Wolf Paquin: had to go get some halloween candy
[8:02:28 PM] Kai Wolf Paquin: oh, K I'll try that
[8:03:22 PM] Kai Wolf Paquin: nope. Still having problems
[8:04:14 PM] Random Davis: but you said it was better when you held it down halfway
[8:04:21 PM] Random Davis: also, make sure the lights are off in the room
[8:04:24 PM] Random Davis: or
[8:04:37 PM] Random Davis: cover up the CdS cell and see fi hte humming goes away
[8:05:18 PM] Kai Wolf Paquin: yeah, it has to do with the CdS cell, becuase it acts normal when Its on it's own
[8:05:41 PM] Random Davis: did you try covering up the CdS cell?
[8:06:14 PM] Random Davis: remember, it's the one that looks like one of these: http://img.alibaba.com/photo/11285760/Cds_Photoconductive_Cell_Photoresistor_LDR.jpg
[8:07:11 PM] Kai Wolf Paquin: K I fixed it. It was really dumb. I just had to wiggle the wires for a while then suddenly it went away
[8:07:32 PM] Random Davis: huh
[8:07:54 PM] Random Davis: try varying the audio output levels to the bulb, too
[8:08:05 PM] Random Davis: make it stronger, or weaker
[8:08:11 PM] Kai Wolf Paquin: K one sec
[8:14:32 PM] Kai Wolf Paquin: Crap, no It's still doing it.
[8:14:42 PM] Random Davis: mess with the wires again
[8:14:55 PM] Kai Wolf Paquin: It only was reduced on the headphones, not in the recordings
[8:15:06 PM] Random Davis: weiird
[8:15:19 PM] Random Davis: so it even hums when you compleyelt cover up the CdS cell?
[8:15:37 PM] Random Davis: and make sure you're not touching any exposed wires, as that will add humming
[8:16:07 PM] Kai Wolf Paquin: nope, it's all good
[8:16:55 PM] Kai Wolf Paquin: Maybe I should put this on hold and work on underwater recording. Then we could possibly get together and work on this
[8:17:05 PM] Random Davis: sure
[8:17:11 PM | Edited 8:17:15 PM] Random Davis: I'd love to help
[8:17:18 PM] Kai Wolf Paquin: K,
[8:17:44 PM] Kai Wolf Paquin: So maybe this weekend or if I can get a ride from my mom or dad, after school one day
[8:18:19 PM] Kai Wolf Paquin: Oh! this friday I have no school. Would that work for you afterwords>
[8:18:20 PM] Kai Wolf Paquin: ?
[8:18:36 PM] Random Davis: I can come over there if you want
[8:18:43 PM] Random Davis: is your weekend free, too?
[8:19:07 PM] Kai Wolf Paquin: yeah, except saturday. I have the SAT
[8:20:09 PM] Random Davis: at what time?

Last Post to do With Cans (hopefully)

So, I finally finished all my work with cans today, all the editing is done and I am not very satisfied.

It seems that once I amplify everything to a consistent volume, I notice lots of little problems with the recording which are really hard to notice otherwise. Also, there are little points of silence I didn't notice when originally recording.

I also noticed in the presentation form that it would be really hard to listen to all the recordings for every test. Thus a solution for all my problems.

In every recording, the best sound that is easiest to tell the difference between is the sax and the electric guitar. I decided that I will edit all these parts out in order to present this experiment, and offer the other files at the end of the cd for presentation.

Anyway the main idea of this post is to announce that I can't continue with my can recordings due to time, and I have to make some exceptions and compromises with my presentation.

Anyway, as of today, I am going to move on and do bigger and better things. I will only move backwards if I absolutely need to.

The End
