That libsndfile supports, for example WAV,įLAC, OGG and MAT files (see Known Issues below about writing OGG files). The soundfile module can open all file formats Read/Write Functionsĭata can be written to the file using soundfile.write(), or read from Libsndfile error message in the LibsndfileError.error_string attribute. Provides the libsndfile internal error code in the de attribute and the raw Particularly, a LibsndfileError subclass of this exception is raised onĮrrors reported by the libsndfile library. In case of API usage errors the soundfile module raises the usual ValueError or TypeError.įor other errors SoundFileError is raised (used to be RuntimeError). Of the platforms we have precompiled libsndfiles for. To build binary wheels for all supported platforms, run python build_wheels.py, which will python setup.py bdist_wheel for each Of the wheel is around one megabyte, a matching libsndfile has beenīundled (without libsndfile, it’s around 25 KB). To build a binary wheel that contains libsndfile, make sure toĬheckout and update the _soundfile_data submodule, then run However, soundfile relies on libsndfile, and optionally ships its Soundfile itself does not contain any compiled code and can beīundled into a wheel with the usual python setup.py bdist_wheel. Version of Python, you might need to install NumPy and CFFI separately,įor example using the Anaconda package manager or the Unofficial Windowsīinaries for Python Extension Packages. If you are running on an unusual platform or if you are using an older Your distribution’s package manager, for example sudo apt install libsndfile1. You install the source module, you need to install libsndfile using This will also install a current version of the library libsndfile. On Windows (64/32) and OS X (Intel/ARM) and Linux 64, In a modern Python, you can use pip install soundfile to downloadĪnd install the latest release of the soundfile module and itsĭependencies. The soundfile module depends on the Python packages CFFI and NumPy, and the Package or source wheel instead of the platform-specific wheels. Prefer using the system-provided libsndfile, install the source The packaged libsndfile in the platform-specific wheels is triedīefore falling back to any system-provided libsndfile. In 0.12.0, we changed the load order of the libsndfile library. The oldĬtype arguments still work, but are now officially deprecated. Methods to dtype, using the Numpy dtype notation. In 0.9.0, we changed the ctype arguments of the buffer_* Also, the order of arguments of the write functionĬhanged from write(data, file. In 0.8.0, we changed the default value of always_2d from True Inconsistencies, particularly in the the ordering and naming ofįunction arguments and the removal of the indexing interface. Notably, we changed the import name from import pysoundfile to The soundfile module has evolved rapidly in the past.
