This fuction requests a buffer array for delivering audio to the
|
|
Packit |
06404a |
encoder for compression.
|
|
Packit |
06404a |
|
|
Packit |
06404a |
The Vorbis encoder expects the caller to write audio data as
|
|
Packit |
06404a |
non-interleaved floating point samples into its internal buffers.
|
|
Packit |
06404a |
|
|
Packit |

|
|
Packit |
06404a |
The general procedure is to call this function with the number of samples
|
|
Packit |
06404a |
you have available. The encoder will arrange for that much internal storage
|
|
Packit |
06404a |
and return an array of buffer pointers, one for each channel of audio.
|
|
Packit |
06404a |
The caller must then write the audio samples into those buffers, as
|
|
Packit |
06404a |
float values, and finally call vorbis_analysis_wrote() to tell the
|
|
Packit |
06404a |
encoder the data is available for analysis.

Return Values
|
|
Packit |
06404a |
Returns an array of floating point buffers which can accept data.
|
|
Packit |
06404a |
A (**float) where the first index is the channel, and the second is
|
|
Packit |
06404a |
the sample index.
