Hi all,
Thanks for your previous help Rob and others. So here's my situation. I've managed to get a working example of minimad going under MSVC6 which decodes very nicely... I was just doing this so I could have something to compare my other project to. My other project is a minimad example which I am trying to port to a SHARC DSP. In any case, after making some minor modification to the code (replacing some functions in minimad that were unavailable in my DSP's library's) I found that the output pcm was not correct. (I'm inputting a simple kHz sine wave and the output looks like a gradually expanding amplitude sine wave with some randomness..) I have set all the necessary pre-processor defines for my architecture... ex FPM_DEFAULT for now until I write my own asm routine.
What I would like to be able to do is see exactly how each individual input sample is being decoded and stored as pcm (pcm->samples[]). My problem is that I can't see where the code is outputting to the pcm->samples location. I'm a relatively inexperienced programmer, but would like to think I can manage to figure things out given time. What I imagine is happening is that these locations aren't being filled directly, but being passed an address somehow.
Sorry for this lame question, but I have spent hours stepping through the code and still cannot see how the pcm->samples are being filled. I believe the problem that I am having is related to some of the math which is performed on each sample. Seeing how each sample is being treated and comparing it with a working example should help me figure out a fix for this.
If anyone has any tips I would be extremely grateful.
Matt
