Could 24 bit audio data be encoded on dm6467?

Hi,

  C6467 has C64x+ DSP, we can execute audio encoder on this DSP for 24 bit audio. We do not have any 24 but encoders from TI on C64x+ but couple of our decoders support 24 bit data.

Hi  Venkat,

I have successfully encoded 16bit audio data to aac file.
But, when I encoded 24bit audio data, I got a error message:
Failed to create aac audio encoder

So I debugged the program, and found that it was wrong:
...
dynamicParams.inputBitsPerSample     = 24;  //default 16
...
hAe = Aenc_create(hEngine, "aacenc", (AUDENC_Params *) &aacParams, &dynamicParams);
if (hAe == NULL) {
        ERR("Failed to create aac audio encoder\n");
        cleanup(THREAD_FAILURE);
}

Could you tell me how to encode 24 audio data?

Thanks.

Best regards.

Hi Armstrong,

TI's AACEncoder on C64x+ does support only 16bit PCM.  It won't support 24bit audio data.

Hi,

  I think we did not get your question right? My answer earlier was related to feasibility of implementing 24bit audio encoder on TI's DM6467. Our AAC encoder implementation on C64x+ supports only16 bit audio. As I mentioned on my previous post, we do not have 24bit encoders on C64x+.
