    Hi All I am a student working on TMS320C5510 DSK. I had read a audio file from the program ( using fopen and fread) and done processing and then had written back in a another file (using fwrite) . Now to confirm whether it is done the processing or not I plot the both file using MATLAB and verify...

    Kieran Yu
    In the VA5505's audio example, when you played your own audio signal to the codec, and then transfer it into DSP to do a lowpass filtering , you will hear some unexpected noise mixed in your filtered output audio signal if you use a earphone to hear it . The noise you hear is a result of the block...
