split returns a generator of AudioRegion objects

audio_regions = auditok.split( "humming.wav", min_dur=0.2, # minimum duration of a valid audio event in seconds max_dur=4, # maximum duration of an event max_silence=0.3, # maximum duration of tolerated continuous silence within an event energy_threshold=55 # threshold of detection )

for i, r in enumerate(audio_regions):

# Regions returned by `split` have 'start' and 'end' metadata fields
print("Region {i}: {r.meta.start:.3f}s -- {r.meta.end:.3f}s".format(i=i, r=r))

# play detection
# r.play(progress_bar=True)

# region's metadata can also be used with the `save` method
# (no need to explicitly specify region's object and `format` arguments)
filename = r.save("region_{meta.start:.3f}-{meta.end:.3f}.wav")
print("region saved as: {}".format(filename))

` humming.wav is a file bigger than 25 MB

Hi, There's apparently a problem with you audio file, standard wave module cannot load it:

wave.Error: unknown format: 3

Please make sure that this a valid wav file.

OK I will check whether this wave file is broken
