Introduction

csound-bitbitch provides opcodes for sample level alterations, glitches and other mishaps

Requirements

• Csound libraries
• Cmake >= 2.8.12

Building

Create a build directory at the top of the source tree, execute cmake .., make and optionally make install as root. If the latter is not used/possible then the resulting module can be used with the --opcode-lib flag in Csound. eg:

cd csound-bitbitch
mkdir build && cd build
cmake ..
make && sudo make install

Opcode overview

bitchrandom

• aout bitchrandom kamp, kdensity, krepeattrig, kbufread, kbufmode [, ibufsize]

Create a stochastic data stream

• aout : audio output

• kdensity :

bitchglitch

• aout bitchglitch ain, kread, ksizeratio

Perform a basic buffered retrigger read on the input

• aout : audio output

• ain : audio input

• kread : 0 = write, 1 = read
• ksizeratio : size ratio of total buffer for the retriggered read

bitchwreck

• aout bitchwreck ain, ibuffersize, kwrite

Aleatoric buffer reading

• aout : audio output

• ain : audio input

• ibuffersize : buffer size in seconds
• kwrite : 0 = read, 1 = write

bitchpan

• aL, aR bitchpan ain, ibuffersize, kpansamples

Harsh sample level binary panning

• aL : left audio output

• aR : right audio output

• ain : audio input

• kpansamples : number of samples to alternate between channels

bitchbuffer1

• aout bitchbuffer1 ain, ibuffersize,

Harsh sample level binary panning

• aL : left audio output

• aR : right audio output

• ain : audio input

• kpansamples : number of samples to alternate between channels

bitchaverage

• aout bitchaverage ain, [kbufferratio = 1, ibuffersize = ksmps]

Buffered sample averaging

• aout : audio output

• ain : audio input

• kbufferratio : ratio of buffer size to read and write
• ibuffersize : buffer size in samples

bitchpeaker

• aout bitchpeaker ain [kbufferratio = 1, kconsiderationratio = 0.3, ibufferdecimation = 64, ibuffersize = ksmps]

Experimental peak resculpture

• aout : audio output

• ain : audio input

• kbufferratio : ratio of buffer size to read and write
• kconsiderationratio : ratio of buffer to consider in resculpture
• ibufferdecimation : buffer decimation divisor
• ibuffersize : buffer size in samples
