I want to use my Pi3 as a portable mp3 player. Is there a way to implement a traditional style tone control ? Bass, treble, volume ? If it has to be done in DSP how would I go about it, or should it be done in hardware? Always wanted to get into DSP apart from the textbooks, this seems like a good place to start. Perhaps the Wolfson Audio card would do the job? Thanks in advance.
