1.1

what is libmusepack

libmusepack is a library that decodes musepack compressed audio data. Musepack is a free, high performance, high quality lossy audio compression codec. For more information on musepack visit http://www.musepack.net.

using libmusepack

Using libmusepack is very straightforward. There are typically four things you must do to use libmusepack in your application.

step 1: implement an mpc_reader to provide raw data to the decoder library

The role of the mpc_reader is to provide raw mpc stream data to the mpc decoding library. This data can come from a file, a network socket, or any other source you wish.

See the documentation of mpc_reader for more information.

step2: read the streaminfo properties structure from the stream

This is a simple matter of calling the streaminfo_init() and streaminfo_read() functions, supplying your mpc_reader as a source of raw data. This reads the stream properties header from the mpc stream. This information will be used to prime the decoder for decoding in the next step.

step 3: initialize an mpc_decoder with your mpc_reader source

This is just a matter of calling the mpc_decoder_setup() and mpc_decoder_initialize() functions with your mpc_decoder, mpc_reader data source and streaminfo information.

step 4: iteratively read raw sample data from the mpc decoder

Once you've initialized the decoding library you just iteratively call the mpc_decoder_decode routine until it indicates that the entire stream has been read.

For a simple example of all of these steps see the sample application distributed with libmusepack in src/sample.cpp.
