Treatment encodeMonoWav

audio/encode::encodeMonoWav

Parameters

↳ var sample_rate: u32

Inputs

⇥ signal: Stream<f32>

Outputs

↦ data: Stream<byte>
↦ errors: Stream<string>
↦ failed: Block<void>

Encode a normalised mono f32 signal into a WAV byte stream.

Samples arrive through signal as f32 values in the range [-1.0, 1.0]. They are encoded as 32-bit IEEE float PCM and emitted through data as a continuous stream of raw WAV bytes, suitable for writing directly to a file or sending over a network.

sample_rate must match the rate at which the samples in signal were produced.

errors emits a message if encoding fails. failed triggers on any fatal error.
