Audio Comperssion Manager

Just wondering if anyone is aware of any sources on the web where I could find info relating to the ACM API's or if anyone knows if I could use the ACM API's in VB to compress audio data. I am creating an app that records tel conversations in a multi media contact centre enviroment and have had no problems so far with creating the wave file and streaming the data into it using the wave apis and the multi media input output apis. The problem is that in a PCM format (8000hz,8bit,mono), a 10 second recording gives me a 81KB file, but using the DSP Group TrueSpeech CODEC should compress this to +-8KB. I don't no if I'm going about it the right way - If anyone has any ideas or if anyone knows where I could get some material on the ACM API's - PLEASE let me know.

Many thanks

I am facing the same thing myself.

I've looked everywhere and all I can find, which may be of use to you, is a vb program that interfaces with a C++ dll which interfaces with Lame_enc.dll which encodes/decodes mp3 files. This can be played through standard API, but cannot directly target soundcards, should you want to, without going through Audio Compression Manager first. This is the problem that I am facing!

If you want the code let me know, I'm it's not buried too deep within the computer.
