Crate sim_lib_stream_audio 

PCM source and sink adapters for STREAM 6.

This crate keeps PCM I/O in library space. The in-memory source and sink are deterministic test backends; stream observation still goes through sim-lib-stream-core packets and spines.

Structs

MemoryPcmSink

In-memory PcmSink that records every written buffer and flush.

MemoryPcmSource

In-memory PcmSource that replays a fixed queue of buffers.

PcmBuffer

Owned block of PCM audio: a PcmSpec plus a frame count and the matching interleaved sample data.

PcmFormatDescriptor

Runtime citizen that carries a PcmSpec as a stream/PcmFormat object.

PcmPumpSummary

Tally of how much audio moved through a pump or stream-adapter run.

PcmSpec

Audio format description for a PCM stream: channel count, sample rate, and sample encoding.

Enums

PcmSampleFormat

Sample encoding of a PcmPacket.

Traits

PcmSink

Push sink for PCM audio buffers in a fixed PcmSpec.

PcmSource

Pull source of PCM audio buffers in a fixed PcmSpec.

Functions

f32_interleaved_to_planar

Splits interleaved f32 samples into one Vec per channel.

f32_planar_to_interleaved

Interleaves per-channel f32 planes into a single interleaved Vec.

f32_sample_to_i16

Converts one normalized f32 sample to i16, clamping to [-1.0, 1.0].

f32_samples_to_i16

Converts a slice of normalized f32 samples to i16 via f32_sample_to_i16.

i16_interleaved_to_planar

Splits interleaved i16 samples into one Vec per channel.

i16_planar_to_interleaved

Interleaves per-channel i16 planes into a single interleaved Vec.

i16_sample_to_f32

Converts one i16 sample to the normalized f32 range [-1.0, 1.0].

i16_samples_to_f32

Converts a slice of i16 samples to normalized f32 samples via i16_sample_to_f32.

pcm_format_class_symbol

Returns the stream/PcmFormat class symbol under which PcmFormatDescriptor is registered.

pcm_source_to_stream

Drains a PcmSource into a pull-mode sim-lib-stream-core StreamValue.

pump_pcm

Drains source into sink, then flushes the sink.

stream_to_pcm_sink

Drains a sim-lib-stream-core StreamValue into a PcmSink.
