Appendix B: Multichannel Audio Tool

The MCAudio sample application is a tool for creating multichannel files in WAV and AVI format. The application is located in the AVBook/bin directory. Although MCAudio isn t particularly sophisticated ” it s by no means a professional audio-editing tool ” it does give you a quick way to generate 5.1 and 6.1 audio files. And best of all, we give you the source code, in case you want to modify it.

Setup

The MCAudio tool requires two DLLs, MultiAudio.dll and Wavdest.ax, which are included with the executable in the binaries directory. Use the Regsvr32 utility to register these DLLs.

 regsvr32 multiaudio.dll  regsvr32 wavdest.ax 

(Yes, Wavdest.ax is a DLL despite the unusual file extension.)
