The MAS3507D is a Decoder only - the 3587F is an encoder. They've also got a GSM codec - audio quality probably good enough for a phone, and the data rate is more amenable to a PIC. What about just using a Voice / Data modem? -Randy Glenn Measure twice, cut once, curse, discard.

It can be controlled by the PIC, and then save the conversation in MP3 format. Lots of built-in features. Regards Chris A ----- Original Message ----- From: "Junque Male" To: Sent: Wednesday, 30 January, 2002 13:02 PM Subject: [OT] Telephone to Soundcard PC based I want to record telephone conversations on my PC. The control part is easily done with a pic. off hook and on hook control and even did a pad with an old transformer from the junkbox. Now that I have the hardware I am stuck on the proper software.- all that I have found is manual - I need something that I can tell to start/stop and that offers compression. AGC is another problem - the far voice gets buried in noise sometimes. I need a fast attack/release either done in software or.hardware Any links? Ideas?
