Subject description: Reducing the quality of audio files
Reply with quote  Mark this post and the followings unread

Hello all,

I'm looking for a way to "degrade" the quality of an audio file (via sndbuf) to create a lo-fi aesthetic, similar to what you would get if you recorded sound on a cheap cassette tape recorder. Any thoughts on how this could be achieved?

Thanks in advance!

welcome

Cassette .. I'd add a little noise, a bit of tape saturation / distortion, filter the highs off a bit, maybe warble the speed with a modulated delay line .. compress a bit ... that is about what tape does I think.

I'm not a ChucK programmer though .. but what I've seen of it I think this could all be done.

Routing multiple things to a module's input can't be done using the normal chuck operator way, but you can set stuff up and then do a loop that changes things and waits exactly one sample between every change. Then apply Blue Hell's ideas above.

Some pseudo-code (you'll have to look up the UGens) that does some random modulation to a filter's frequency:

Code:
SawOsc osc => Filter filter => dac;
RandomOsc randomOsc => blackhole;


while(true) {
   1000.0 + randomOsc.last() / 100 => filter.freq;

   1::samp => now;
}
