resampy_resampler

Resampy-based audio resampler implementation.

This module provides an audio resampler that uses the resampy library for high-quality audio sample rate conversion.

class pipecat.audio.resamplers.resampy_resampler.ResampyResampler(**kwargs)

Bases: BaseAudioResampler

Audio resampler implementation using the resampy library.

This resampler uses the resampy library’s Kaiser windowing filter for high-quality audio resampling with good performance characteristics.

Deprecated since version 1.2.0: ResampyResampler is deprecated and will be removed in Pipecat 2.0. Use SOXRAudioResampler, create_file_resampler(), or create_stream_resampler() instead.

__init__(**kwargs)

Initialize the resampy resampler.

Parameters:

**kwargs – Additional keyword arguments (currently unused).

async resample(audio: bytes, in_rate: int, out_rate: int) → bytes

Resample audio data using resampy library.

Parameters:

• audio – Input audio data as raw bytes (16-bit signed integers).

• in_rate – Original sample rate in Hz.

• out_rate – Target sample rate in Hz.

Returns:

Resampled audio data as raw bytes (16-bit signed integers).
