So I want to make a simple waveform editor for my samplesource site, and I was a bit leary, but after a bit of googling today, I found a few seemingly decent resources. One specifically for Java (however the damn site is still loading after fucking 10 minutes, I'm saving that puppy to disk so I don't have to reload it again.), and a few questions on usenet...

Basically from what I can tell is I'd have to analyze the file (with a wave I think this is easier than like mp3 or ogg, but there are libs to use so I'll try those, basically I think I could just decode the ogg/mp3 to a wav, then go from there. dunno for sure) Then, in the example someone mentioned... scan every 256 samples. That seems like low res, but if you figure that there's 44000 samples per second, then that's still like between 100-200 samples a second. For each sample, merely y++, then plot the x based on the data for that sample (that is, I believe, the amplitude of the signal... In the thing I read, they suggested taking the strongest signal from that set of samples, and use that to plot it) I'm still quite hazy on it, but I have a general grasp of the concept. When I have more time I'll look at the docs in further depth and think it through...

The next issue is going to be which framework to use. I want something that's useable in the browser so it can be either Java, Flash or Javascript. The next trick is to figure out how to allow a user to draw a selection of the sample, and export that to a file to be uploaded to the wiki (this would be done on the server I believe, encoding the little selection as an ogg file, as that's what mediawiki supports) A lot of shit to deal with, of course, but I think it's doable.

I tried looking at the audacity source code, but being that it's in CVS, I'm not sure I know where to begin. I looked at a couple spots that seemed promising, but there wasn't much info that was usable to me.

is the header file that appears to contain the code for selecting sections of a wave file.

This is for my own reference, as well as for those who give a rat's ass... I'm posting this so I can easily find it later... :)

Upload dialog??? Hmmm.... this could be of use as well...

Butt Probe

"Metasonix is a little company run by vacuum tube guru Eric Barbour. They build expensive, esoteric and surprisingly funny music gear from arcane vintage electronic components. Eric’s latest invention is the Butt Probe. Basically, it’s a fuzz box, in the way that Lamborghini Murciélago is basically a car.

Unlike the Lambo, the Butt Probe comes with knobs marked ‘Fist’, ‘Ream’ and ‘Screw’, which control the three ‘4BN6 Beam Modulator’ vacuum tubes, which were designed to be used in cheap TV sets. Eric has repurposed them to create “a vast range of NAUSEATING tonal effects not obtainable with any of the existing effect pedals on the market.”

You can even integrate the Butt Probe into a modular synth setup, using other modules or a sequencer to control the filter. How does it sound? Really, really messed up. The insulting and easily distracted product page (sample quote: “Ann Coulter is up your butt! Al Franken is up your butt! Can’t you feel them wriggling around in ther? It’s NASTY! ”) provides a series of helpful audio examples of the Butt Probe converting anything into a series of rhythmic, squawking bleeps.
All this doesn’t come cheap - the retail price for the limited run of 100 units is $549, but at least you know you it won’t be used on the new Kelly Clarkson single."

Leamon Sound Device:

"The Leamon Sound Device (LSD) is currently installed in a spare private
room. Soon I would like either to install my system or build a new LSD
altogether in a more public space where artists can create and audiences
can listen. Until then, however, I am simply trying to spread the word (or sound)
about a remarkable new way of hearing and making audio.

I am especially eager for composers and musicians to hear the LSD and possibly
create new audio for it. I am at best an amateur and strongly desire to put the power
of the LSD in the hands of those who can exploit it fully."

Do you think that Walker would be interested in this at all? I'm sure it depends on the system itself. Do you guys do things like that? Do you find unkown things like this and support it by showing it? Just curious as to how you get your exhibitions.

On the "more channels" tab, there's some nice clips of bill hicks doing his thang...
