Matlab Audio processing -
i've been assigned homework includes sound processing in matlab, got @ to the lowest degree 3 channels of different frequencies in song, , increment db output depending on channel. it's got work equalizer using 3 channels. biggest problem here getting frequency , magnitude values , save variables separated in channels (low, mid , high) frequencies.
read file using wavread specify filter using fdesign (fdesign help) need 3 filters lowpass, bandpass , high pass. (you may need decimate) use design design filter above specification. need specify & design thrice have 3 channels. can made function , wavread output can passed this. finally utilize filter command filter data. (again 3 filters) now have 3 outputs belong 3 frequencies. (use matlab help good)
ps: assume have signal processing toolbox.
