Audio

Convert absolute amplitude to finite decibels with a silence floor.

Apply one stable zero-state biquad independently to every channel.

Clamp every sample to an inclusive finite interval.

Decode one WAV/PCM, FLAC, or MP3 file and upload planar FP32 samples. This is a synchronous CPU codec boundary followed by device upload. It does not introduce a decoder session or a hidden execution backend. Errors Returns an error for an empty path, file I/O failure, unsupported or malformed media, changing stream parameters, empty decoded audio, checked-size overflow, or device allocation/upload failure.

Decode one in-memory WAV/PCM, FLAC, or MP3 stream and upload planar FP32 samples. Errors Returns an error for empty, unsupported, malformed, or parameter-changing media, empty decoded audio, checked-size overflow, or device allocation/upload failure.

Encode non-empty interleaved FP32 frames as lossless IEEE-float WAV bytes. Errors Returns an error for a zero sample rate or channel count, incomplete frames, or values that exceed the RIFF/WAV 32-bit header limits.

Read planar device samples and encode lossless IEEE-float WAV bytes. This is an explicit blocking host-observation boundary. Errors Returns an error when readback fails or the resulting WAV exceeds checked allocation or RIFF header limits.

Apply linear fade-in and fade-out envelopes measured in samples.

Apply scalar gain in decibels.

Compute HTK triangular-filter mel features in [channels, mels, frames] layout.

Compute orthonormal DCT-II coefficients in [channels, coefficients, frames] layout.

Compute a weighted sum of matching Audio values.

Normalize global peak or RMS level to the configured decibel target.

Apply y[n] = x[n] - alpha*x[n-1] independently per channel.

Resample planar audio using the donor windowed-sinc gather kernel.

Render a finite zero-state Schroeder reverberation tail.

Apply tanh soft clipping with a dry/wet mix.

Encode and write one lossless IEEE-float WAV file. This is an explicit blocking host-observation and filesystem boundary. Errors Returns an error for an empty path, failed readback or encoding, or a host filesystem write failure.

Apply one to 64 stable biquad sections as a zero-state cascade.

Compute magnitude STFT features in [channels, frames, frequency_bins] layout.

Average all channels into one mono channel.

Reduce multichannel audio to [bins, 2] minimum/maximum pairs.
