Common API for reading and writing soundfiles. * Uses installed packages if found (scikits.audiolab) * Implements reading uncompressed formats correctly in any format. * The data is independent of the encoding. All data is presented as float64 * Bitdepth is handled automatically depending on the the actual data

SNDFILE.IO
A simple module providing a unified API to read and write sound-files to and from numpy arrays. If no extra modules are installed, it uses only standard modules and numpy to read and write uncompressed formats (WAV, AIFF).
If other modules are installed (scikits.audiolab, for example), then they are used.
Even without third-party packages, it has certain advantages over the built-in modules wave and aifc
- support for
PCM16,PCM24,PCM32andFLOAT32 - unified output format, independent of encoding (always
float64) - unified API for all backends
API
sndread
- it will read ALL the samples and return a Sample (a tuplet data, samplerate)
- Data will always be as a
numpy.float64, between -1 and 1, independently of bit-rate
sndread_chunked
- will read chunks of frames, avoiding the allocation of all the samples in memory
sndinfo
- return
SndInfo, a namedtuple with all the information of the sound-file
sndwrite
- write 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
