medkit.audio.preprocessing.power_normalizer#

Classes:

PowerNormalizer(output_label[, ...])

Normalization operation setting the RMS power of each audio signal to a target value.
class PowerNormalizer(output_label, target_value=1.0, channel_wise=False, uid=None)[source]#

Normalization operation setting the RMS power of each audio signal to a target value.

Parameters

  • output_label (str) – Label of output normalized segments.

  • target_value (float) – Value to set the RMS power of each segment to.

  • channel_wise (bool) – If True, the normalization is performed per-channel, thus modifying the balance of multichannel signals.

  • uid (str) – Identifier of the normalizer.

Methods:

run(segments)

Return a normalized 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 normalized segment for each segment in segments.

Parameters

segments (List[Segment]) – Audio segments to normalize.

Return type

List[Segment]

Returns

List[~medkit.core.audio.Segment] – Power-normalized segments, one per segment in segments.

property description: medkit.core.operation_desc.OperationDescription#

Contains all the operation init parameters.

Return type

OperationDescription

set_prov_tracer(prov_tracer)#

Enable provenance tracing.

Parameters

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