Common API for reading writing soundfiles
Project description
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
Installation
Make sure that you have libsamplerate installed.
