Other Parts Discussed in Thread: TLV320AIC3254

Really i need help from TI. My aim to capture live audio signal from mic,which should be connected to Audio compression chip, Which should convert to digital and compress it then give to microcontroller unit and again microcontroller will forward same to audio decompression chip, where the speaker is attached and that chip should again convert to analog signal with decompress and play via Speaker.

Hi, Suman,

tlv320aic3254 can do the a/d and d/a conversion that you are looking for.

Thanks for reply Dapkus. I have saw that chip earlier,but i don't think so it will compress digital data after converting from analog. It will just converter not a compressor, if am not wrong. I need to compress it. Because i can't run software CODEC(compress and Decompress) in microcontroller, it need some thin kernal to run. I can't port any kernal to controller due to lack of memory. So i am looking for hardware compression,which will compress the digital data and give to controller. And if controller gives that compress data to that chip.it should capable to decompress it.
