DSP and Audio

Hi guys. I've been programming for a long time but I'm stuck.

What i want to be able to do is have a program receive data from the microphone/line in port so that i can process it.

My boss wants this done in realbasic if possible, but is there an answer to this question, without going to any specific language? Any help at all would be great. Thanks for your time.

Mike

If you are using Windows you need to look into DirectShow probably (best solution) or you need to look into the Windows Media API functions though http://msdn.microsoft.com ... DirectX is the best route though in my opinion, but not required.

Of course I can not tell you how to do this through Real Basic... tell your BOSS that you need to use a more reliable language than BASIC

Computer instruction processing rates are much higher than audio signal rates. Complex real-time processing of such signals can require a LOT of power, however. You need to take advantage of the work put into libraries that accomplish the tasks in ways sweated over by experts. Your boss should realize and appreciate this; reinventing the wheel is rarely a good idea.

If the processing you need to do is trivial, forget I mentioned it .
