Hi,

   

Is there any solution/algorithm available for encoding Speech/Audio input given to one of the ADC inputs in PCM format? My requirement is to record the analog speech or audio from a telephone in PCM G.711 encoded format. Here the sampling is required at 8K samples per second and each sample is of 8-bit length.

   

This requirement is similar to the application note (with algorithm) given for Microchip's dsPIC33F and PIC24 devices.

   

Thank you.
