+<h1>vorbis_analysis_buffer</h1>
+
+<p><i>declared in "vorbis/codec.h";</i></p>
+
+<p>This fuction requests a buffer array for delivering audio to the
+encoder for compression.</p>
+
+<p>The Vorbis encoder expects the caller to write audio data as
+non-interleaved floating point samples into its internal buffers.
+</p>
+<p>
+The general procedure is to call this function with the number of samples
+you have available. The encoder will arrange for that much internal storage
+and return an array of buffer pointers, one for each channel of audio.
+The caller must then write the audio samples into those buffers, as
+float values, and finally call vorbis_analysis_wrote() to tell the
+encoder the data is available for analysis.

+<h3>Parameters</h3>
+<dl>
+<dt><i>v</i></dt>
+<dd>Pointer to the vorbis_dsp_state representing the encoder.</dd>
+<dt><i>vals</i></dt>
+<dd>Number of samples to provide space for in the returned buffer. 1024 is a reasonable choice.</dd>
+</dl>
+
+
+<h3>Return Values</h3>
+<p>Returns an array of floating point buffers which can accept data.
+A (**float) where the first index is the channel, and the second is
+the sample index.<p>
