Hello friends, Can i get the c code or assembly code for the AGC for simple voice gain control for c5510. I will be greatly thankful to you if anybody could help me out .The stuff could be simple . Regards |

You have to specify whether AGC algorithm is based on software (digital scaling) or hardware gain. If hardware, then which board and whic codec (for example, DSK 5510 with AIC23 codec). Normally an AGC that has access to true hardware controlled gain is more effective. -Jeff |

we've written some assembly code for agc here on the C5502. it is running on an 11.025Ksps and a 44.1Ksps channel. i wouldn't call it _simple_ however. due to pcb real estate considerations, we opted for a s/w vs. h/w solution.
