When I asked about which you found to be better, OMAP or Blackfin, one of you (see wyonghao's question) asked about the application and if either are good for professional audio.
Now, ordinarily I'd say neither, as professional audio is typically served by floating-point DSPs such as ADI's TigerSharc, TI's 'C6000, or Freescale's Symphony or one from Cirrus Logic's higher-end lineup.
However, the question is still interesting as the application wyonghao is thinking of may not require the high-end performance (read: cost) these processors can offer. That being said, the performance of the OMAP and Blackfin lines continues to increase, though fixed-point processors still lack the floating-point's precision.
So, to help explore this a bit more and see where DSPs are going with regard to audio, I've started a new discussion in our Forum: Which DSP for audio?.
Take a look and if you have any suggestions, let them be heard. If you're interested in keeping tabs on the discussion, make sure to Track the Thread in your settings to get an email alert when someone posts a comment.
I'll be highlighting some of the better responses here on this blog spot, so feel free to also email me at firstname.lastname@example.org.
Finally, be sure to also sign up for the weekly DSPDesignline newsletter where I'll also be highlighting some of your feedback on these questions. Have a great weekend!
