Convert iLBC compressed audio data wrapped in a CAF file to uncompressed linear PCM and store it into a WAV container.

Content

  1. iLBC

C# fork of the original iLBC source codes. These files have been created by Walking Cat (see copyright information below) These classes are actually used by the test application.

  1. iLBCConverter

Trying to pack the original iLBC C-Sources into a DLL to be imported by other projects. The Sourcefiles have been extracted from the iLBC specification file (rfc3951.txt). This project cannot be compiled by now due to a linker error. If somebody has a clue to fix this, please send a pull request!

  1. iLBCTest

The actual Testapplication. It includes Classes for a CAF reader, a class for a WAV writer and the main class where some sound is converted. You need a file "record_ilbc.caf" in the build folder (e.g. /bin/Debug). You can use the Samplefiles.

  1. Samplefiles

This folder provides an audio file recorded in iLBC (on iOS Device) as well as the same file reconverted to PCM with Apple Libraries on iOS. This can be used as a reference to compare the output on hexadecimal basis.
