The signal chain

One toolkit, from first sample to final file.

Generate

Tones, silence, samples, and arrangements from a compact Ruby DSL.

Transform

Trim, fade, mix, resample, and convert with immutable operations.

Process

Filters, dynamics, delay, reverb, modulation, and mastering chains.

Stream

Process long recordings chunk by chunk with stateful DSP tails intact.

Encode

Write production-ready audio without leaving your Ruby process.

Readable by design

Audio work that reads like Ruby.

Start with a tone, shape its edges, convert the bit depth, and write a WAV. Each transform returns a new audio value, so chains stay predictable and easy to test.

Codec I/O

The formats you need. No shell-out required.

WAV, AIFF, FLAC, and raw PCM are implemented in Ruby. OGG Vorbis support is available through optional native gems.
