To perform sound source localization (20Hz - 20KHz), I am looking for an ADC which can take stereo i/p and sample data at the rate of 200Ksps with 24-bit resolution & data will be transferred to host using USB 2.0.
I found PCM2904 which can fairly good for voice frequency (16-bit with max 48KHz) - a subset of my original req. First off all can I get any information about EVM board build around PCM2904/06?
Next can I get a suggestion which TI Data converter will be best suited for my first req (20-20Khz) to digitize audio with 24-bit & 200ksps & supports USB transfer to host. In fact I need to estimate both azimuth & elevation. Hence 4 channel will be the best suit for me but if it is not feasible to get such a data converter, I can cope with two such 2-channel data converter & use it in a time multiplexing mode
Moreover it should support by either h/w or s/w lib
(1) AEC (Acoustic Echo Cancellation )
(2) Anti-aliasing
(3) noise suppression
