sndfileio 1.2.0

Common API for reading writing soundfiles

This package provides a simple and unified API to read and write sound-files to and from numpy arrays.

API

sndread

• reads all the samples (or a fragment) from a soundfile and returns a tuplet (data, samplerate)

• Data will always be as a numpy.float64, between -1 and 1, independently of bit-rate

sndread_chunked

• reads chunks of frames, avoiding the allocation of all the samples in memory

sndinfo

• returns SndInfo, a namedtuple with all the information of the sound-file

sndwrite

• writes the samples.

• samples need to be a numpy.float64 array with data between -1 and 1

sndwrite_chunked

• allows you to write to the file as samples become available

resample

Resample a numpy array to a new samplerate
