libsndfile ( is a de-facto standard C library for reading and writing sampled sound data on *nix systems.

python-sndfile ports this functionality on several abstraction levels to the python programming language, hopefully replacing the build-in wave module.

development status

python-sndfile currently implements the libsndfile API. A more pythonic interface leaning towards the build-in wave module is part of the next release.

Just released v0.1.

This offers a (almost) 1:1 wrap from the C library to python.

Exceptions include that return values are returned as function return value and not by pointers to python objects in the function argument list.

data = sf_read_float(...)

instead of:
sf_read_float(..., data)

Next up:

  • HTML documentation on usage
  • complete wave module replacement
