BQNoise

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.
