Crate flexaudio_encode 

flexaudio-encode — an add-on that compresses recording chunks into FLAC files as they arrive.

It does not depend on flexaudio-core and accepts only interleaved &[f32] samples. Encoding uses the pure Rust flacenc crate, with no system libraries or runtime network access. It can losslessly compress long recordings to roughly half the size of WAV (for example, a 3-hour meeting recording of about 2 GB becomes a few hundred MB).

Each incoming chunk is encoded in blocks and streamed to a file, so memory use stays constant regardless of recording length. Stream metadata (total sample count, MD5, etc.) is finalized in the header by FlacWriter::finalize.

Example

use flexaudio_encode::FlacWriter;

// Pass flexaudio's canonical format (48 kHz / stereo) directly.
let mut writer = FlacWriter::create("meeting.flac", 48_000, 2).unwrap();
for chunk in some_audio_chunks() {
    writer.write_chunk(chunk).unwrap();
}
writer.finalize().unwrap();
