jperea Posted November 19, 2007 Share Posted November 19, 2007 Hi everybody, I would like to read the information contained in .GSM files using ACM. I can already convert GSM wrapped in WAV files (ex. http://www.nch.com.au/acm/8kgsm.wav) , but I can get nothing from, for example, http://www.nch.com.au/acm/sample.gsm The .GSM format seems to be unpacked (N blocks @ 33 bytes each) while ACM expects a packed format (N groups of 2 frames @ 65 bytes each). It should be quite easy, but the conversion algorithm it's not as trivial as it should be (at least for me, maybe it's Monday, but I promise I spent some time investigating last week, and found almost nothing). So the question is... can someone tell me the way to read each frame from .GSM files so that I can pack them in groups of two? Unfortunately, using Switch is not an option in this phase of the project. Thanks, Juan Perea Link to comment Share on other sites More sharing options...
