Hi All.
My task simplified can be displayed like this: I need to read voice from microphone using adc, encode it with some voice code, decode it, and put on the speaker using dac.
The controller is LPC2148
May be somebody know the voice codec wich can be compiled for this controller and can solve my task in the real time? May be somebody knows where I can download voice codec source adapted for such controllers?
Thank you.
What are your requirements for the CODEC?
Do you need a CODEC at all?
Have you looked at u-Law and A-Law?
How about the GSM specs?
My requirements is real time paralell encoding and decoding. I need the encoded bitrate to be not more then 4.5 kbps. I did not looked at the specifications you tell about - I am not very familiar with it, and honestly I need a code which I can compile for my controller and use in my application. I don't think I can write it by myself from specification
