medkit.audio.preprocessing.resampler#

This module needs extra-dependencies not installed as core dependencies of medkit. To install them, use pip install medkit-lib[resampler].

Classes:

Resampler(output_label, sample_rate[, fast, uid])

Resampling operation relying on the resampy package.

class Resampler(output_label, sample_rate, fast=False, uid=None)[source]#

Resampling operation relying on the resampy package.

Parameters

output_label (str) – Label of output resampled segments.
sample_rate (int) – Target sample rate to resample to, in samples per second.
fast (bool) – If True, prefer speed over quality and use resampy’s “kaiser_fast” filter instead of “kaiser_best”.
uid (str) – Identifier of the resampler.

Methods:

`run`(segments)	Return a resampled segment for each segment in segments.
`set_prov_tracer`(prov_tracer)	Enable provenance tracing.

Attributes:

description

Contains all the operation init parameters.

run(segments)[source]#

Return a resampled segment for each segment in segments.

Parameters: segments (List[Segment]) – Audio segments to resample.
Return type: List[Segment]
Returns: List[~medkit.core.audio.Segment] – Resampled segments, one per segment in segments.

Contains all the operation init parameters.

set_prov_tracer(prov_tracer)#

Enable provenance tracing.

Parameters: prov_tracer (ProvTracer) – The provenance tracer used to trace the provenance.
