BQN scripts for audio synthesis and processing.
- mix.bqn: General mixing utilities, e.g. add, repeat, clip, reverb
- panap.bqn: Fancy mono-compatible panning
- oscillator.bqn: Typical oscillators and noise generators for synthesis
- filter.bqn: IIR filters to adjust tonality
- scale.bqn: Utilities for working with scales (in the normal Western system, 12-TET)
- tracker.bqn: Sequencer to make drum tracks or other arrangements from a text template
- wav.bqn: Read and write .wav files
- soxresample.bqn: Bind SoX's resampler for converting .wav files; only thing I'm not brave enough to do in BQN
See load.bqn and options.bqn for loading multiple scripts and options management.
The following C libraries are used in CBQN if available:
./lib.c(build with$ make), for filters- FFTW's
/usr/lib/libfftw3.so.3, for reverb - SoX's
/usr/lib/libsoxr.so, for resampling
The filtering and reverb functions are also implemented in BQN, so that the only change is faster execution, by a factor of about 10 in each case. There's no BQN resampling implementation, so that SoX is needed to work with files at different frequencies.
