AIC3204 192Khz - PLAYBACK OF 8 KHZ WAV FILE

Expert 2730 points

on my c5505 eZdsp i have configured the codec AIC3204 at 192 Khz recording / playback frequency.

I'd like to reproduce a 8 Khz wav file, saved in 16 bit PCM format with Audacity.

I done this:

with Scilab, i have printed the values of the file.

then I have converted them in Q15 format.

In my DSP code, i created an array with these values.

The problem is that when i try to reproduce it, i hear only bad noise, not the sound.

What should I do?

Thanks in advance

Hi, Paolo,

Have you noticed this behavior with the 'AIC3204 and a different audio source?. I am not sure if this question is related to the 'AIC3204 audio codec as it seems related to the handling of your playback file within the DSP, not with the audio codec configuration. Maybe you could ask my colleagues of the C5000 Ultra Low Power DSP Forum could help you with the DSP data handling.
