Crate sim_lib_stream_file 

File-backed source and sink adapters for STREAM 6.

The crate keeps host filesystem access behind explicit stream file capabilities: reads require fs/read, writes require fs/write, and compatibility stream.file.* aliases are accepted by the gates. Each read or write is recorded as a KERNEL 6 filesystem effect. SMF support reuses the in-tree MIDI file codec; WAV support is limited to canonical little-endian PCM16 RIFF/WAVE because that is the PCM packet format implemented by the stream audio layer. Bounded float-to-PCM16 conversion, finite channel matrices, seeded TPDF/noise-shaped dither, and their clipping reports live here beside that canonical WAV owner rather than in analysis or devices.

Structs

ChannelMatrix

Finite row-major channel mapping applied before sample quantization.

Pcm16Conversion

PCM16 samples plus visible mapping, clipping, and quantization evidence.

PcmConversionReport

Audit report for one channel-map and PCM16 quantization pass.

QuantizationPolicy

Hard input bound and explicit quantization policy.

WavStream

A PCM stream decoded from a WAV file together with its sample format.

Enums

DitherPolicy

Dither and error-feedback policy applied in the PCM16 quantizer.

PcmConversionError

Invalid bounded channel mapping or PCM quantization request.

Functions

cassette_expr_to_stream

Decodes a cassette expression and replays it as a stream.

cassette_to_stream

Replays a recorded cassette back into a stream.

convert_f32_to_pcm16

Maps bounded interleaved f32 PCM and quantizes it to signed PCM16.

convert_f32_to_wav_bytes

Maps and quantizes bounded interleaved floats through the canonical PCM16 converter, then encodes them through this crate’s WAV owner.

pcm16_samples_to_wav_bytes

Encodes already-quantized interleaved samples as canonical PCM16 WAV.

pcm_buffers_to_wav_bytes

Encodes PCM buffers into canonical PCM16 WAV bytes.

read_smf_stream

Reads a Standard MIDI File from path and opens it as a MIDI stream.

read_wav_stream

Reads a canonical PCM16 WAV file from path and opens it as a PCM stream.

smf_bytes_to_stream

Parses Standard MIDI File bytes and opens them as a MIDI stream.

smf_file_to_stream

Opens an already-parsed Standard MIDI File as a MIDI stream.

stream_file_read_capability

Returns the capability gating filesystem reads (fs/read).

stream_file_write_capability

Returns the capability gating filesystem writes (fs/write).

stream_to_cassette

Records a stream into a cassette using the given transport profile.

stream_to_cassette_expr

Records a stream into a cassette and encodes it as an expression.

stream_to_smf_bytes

Drains a MIDI stream and encodes it as Standard MIDI File bytes.

stream_to_smf_file

Drains a MIDI stream into a single-track SmfFile with tpq resolution.

stream_to_wav_bytes

Drains a PCM stream and encodes it as canonical PCM16 WAV bytes.

validate_cassette_fixture_path

Validates a cassette against a golden fixture file at path.

wav_bytes_to_stream

Decodes canonical PCM16 WAV bytes and opens them as a PCM stream.

write_smf_stream

Drains a MIDI stream and writes it to path as a Standard MIDI File.

write_wav_stream

Drains a PCM stream and writes it to path as a canonical PCM16 WAV file.
