Sample 0 and ending at sample 44099 the second slice startsĪt sample 44100 and lasts until the end of the input file: Input file loop.wav and lasts exactly one second, starting at

create_first ( bool ( optional )) – always create the slice at the start of the fileĬreate two slices: the first slice starts at the beginning of the.

hopsize ( int ( optional )) – number of samples read from source per iteration.

samplerate ( int ( optional )) – samplerate to read the file at.

output_dir ( str ( optional )) – output directory to write the slices to.timestamps_end ( list of int (optional)) – time stamps at which to end the slices.timestamps ( list of int) – time stamps at which to slice, in samples.source_file ( str) – path of the resource to slice.If create_first is True and timestamps does not start with 0, theįirst slice from 0 to timestamps - 1 will be automatically added. Hopsize and does not change the output slices. The hopsize parameter simply tells source to use this Timestamps_end should be expressed in the re-sampled signal.

When using a sampling rateĭifferent to the one of the original files, timestamps and The default samplerate is 0, meaning the original sampling rate Will be written in output_dir, after creating the directory if If output_dir is unspecified, the new slices will be written in Otherwise, timestamps_end should be a list with the same lengthĪs timestamps containing the locations of the end of each slice. Timestamps_end = timestamps-1, or the end of file. If timestamps_end is unspecified, the slices will end at This function reads source_file and creates slices, new smallerįiles each starting at t in timestamps, a list of integerĬorresponding to time locations in source_file, in samples. slice_source_at_stamps ( source_file, timestamps, timestamps_end=None, output_dir=None, samplerate=0, hopsize=256, create_first=False ) ¶
