+'wavefile' python module to read and write audio files.
+It is a pythonic wrapper to the sndfile library featuring:
+* Attribute access to format, channels, length, sample rate...
+* Numpy interface using in place arrays (optimal for block processing)
+* Works as context manager
+* Different objects for reading and writing (no modes, consistent interface)
+* Shortened constants accessing for formats and the like
+* Matlab like whole file interface (not recommended but convenient)

+You can find the latest version at:
