Hi,
I'm using c5545 booster pack to implement fir hamming window order 161 bandpass filter. Booster pack came inbuilt with aic3206 audio codec.
1) I would like to run my filters with different sampling rates. How do i set that in my code so that my codec start sampling at that rate? following attached is the code file
2) Also i tried running the fir filter hamming window 161 by getting coefficients from matlab and used the default codec setting of 48khz and played a audio file. but the audio output is not as intended(bandpass is not working as it should be). While calculating the filter coefficients in matlab I used 48000 as the sampling rate while calculating the cutoff frequencies of banpass as 2*30/48000 and 2*300/48000. I'm interested in 30hz-300hz bandpass. Why do you think my filter is not working as intended?. Thanks in advance(Please visit the site to view this file)
