+ Media source to read blocks of consecutive audio samples from file.
To write to file, use ::aubio_sink_t.
+ Depending on how aubio was compiled, the following sources will be available.
+
+ When creating a new source using ::new_aubio_source, the new function of each
+ of the compiled-in sources will be used, in the following order, until one of
+ them gets successfully created. If all sources returned NULL,
+ ::new_aubio_source will return NULL.
+
\b \p source_avcodec : libav
aubio can be optionally compiled with [libav](http://libav.org), which can
different network protocols such as HTTP.
\b \p source_apple_audio : ExtAudioFileRef
-
+
On Mac and iOS platforms, aubio should be compiled with CoreAudio [Extended
Audio File Services]
(https://developer.apple.com/library/mac/documentation/MusicAudio/Reference/ExtendedAudioFileServicesReference/Reference/reference.html).
[libsndfile](http://www.mega-nerd.com/libsndfile/), which can read [most
uncompressed formats](http://www.mega-nerd.com/libsndfile/#Features).
+ \b \p source_wavread : native WAV reader
+
+ A simple source to read from 16-bits PCM RIFF encoded WAV files.
