Can I use SigmaDSP to decode MP3/WAV/AAC?

Question:

I have read through SigmaDSP datasheet, and I find no related information on the MP3/WAV/AAC decoding engine for SigmaDSP.

 

Is there any available audio decoder for SigmaDSP like those modules for Blackfin?

 

Also, is there support for formats like Dolby AC3?

Answer:

The SigmaDSP's core is not capable of frequency domain processing, and therefore it cannot be used to decode/encode MP3/WAV/AAC like the Blackfin or Sharc. SigmaDSP simply takes linear PCM data in and processes it before outputting it as linear PCM data. It is therefore usually referred to as a "post-processor", since it is not involved in any tasks other than audio signal processing.
