class data_juicer.ops.filter.audio_duration_filter.AudioDurationFilter(min_duration: int = 0, max_duration: int = 9223372036854775807, any_or_all: str = 'any', *args, **kwargs)

Bases: Filter

Keep data samples whose audios’ durations are within a specified range.

__init__(min_duration: int = 0, max_duration: int = 9223372036854775807, any_or_all: str = 'any', *args, **kwargs)

Initialization method.

Parameters:

• min_duration – The min audio duration to keep samples in seconds. It’s 0 by default.

• max_duration – The max audio duration to keep samples in seconds. It’s sys.maxsize by default.

• any_or_all – keep this sample with ‘any’ or ‘all’ strategy of all audios. ‘any’: keep this sample if any audios meet the condition. ‘all’: keep this sample only if all audios meet the condition.

• args – extra args

• kwargs – extra args

compute_stats_single(sample, context=False)

Compute stats for the sample which is used as a metric to decide whether to filter this sample.

Parameters:

• sample – input sample.

• context – whether to store context information of intermediate vars in the sample temporarily.

Returns:

sample with computed stats

process_single(sample)

For sample level, sample –> Boolean.

Parameters:

sample – sample to decide whether to filter

Returns:

true for keeping and false for filtering
