tur-rtaudio

Cross-platform audio I/O for Turmeric via RtAudio. Enumerate devices, open input/output streams, and drive audio with a Turmeric callback or pull loop.

Overview

tur-rtaudio is a cmake-dep spice that wraps RtAudio. It exposes the common audio surface: query the available audio APIs and devices, open a stream at a chosen sample rate and buffer size, and start/stop/close it.

Pairs naturally with tur-rtmidi for "audio + MIDI" applications and with tur-wav for file-based I/O. Use it for synths, effects boxes, recorders, and any real-time audio program.
