tur-wav

WAV and PCM audio file read/write for Turmeric via libsndfile.

Overview

tur-wav is a cmake-dep spice that wraps libsndfile. It exposes a small file-oriented surface: wav-open-read returns a handle you can wav-seek and wav-read-float from, and wav-open-write / wav-write-float pairs the same shape for output. An info module reports sample rate, channel count, and frame count.

Use it to load samples for tur-rtaudio streams, record output to disk, or batch-process audio offline.
