Module Contents

class medkit.audio.preprocessing.power_normalizer.PowerNormalizer(output_label: str, target_value: float = 1.0, channel_wise: bool = False, uid: str | None = None)

Bases: medkit.core.audio.PreprocessingOperation

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

Parameters:

output_labelstr

Label of output normalized segments.

target_valuefloat, default=1.0

Value to set the RMS power of each segment to.

channel_wisebool, default=False

If True, the normalization is performed per-channel, thus modifying the balance of multichannel signals.

uidstr, optional

Identifier of the normalizer.

run(segments: list[medkit.core.audio.Segment]) → list[medkit.core.audio.Segment]

Return a normalized segment for each segment in segments.

Parameters:

segmentslist of Segment

Audio segments to normalize.

Returns:

list of Segment

Power-normalized segments, one per segment in segments.
