Hi Roman, Dolby and DTS licensing is expensive.You need DTS and Dolby licenses to buy the parts. You are not going to be able purchase the ROM SHARC parts for just MP3. An MP3 decoder and encoder may be available that does not require the ROM version of the SHARC. You may still need to resolve licensing issues. We have a ADSP-21469 SHARC based high performance audio system (Danville dspMusik 2/8) that can support this kind of application. One of our customers is using it with Dolby Decoders. I suggest you contact Paul Beckmann of DSP Concepts (www.dspconcepts.com). He may have a solution. Al Clark www.danvillesignal.com
Hi Roman,

If you are not tied to the specific DSP family you can consider software
modules for Blackfin. The full list is here:
http://www.analog.com/en/embedded-processing-dsp/blackfin/content/blackfin_software_modules/fca.html

I read somewhere that some of these modules are available in the object
code format (with no source code provided) at no cost. Consult ADI about
licensing terms for MPEG codecs.

Thank you, Alexander. :-) This is interesting options, but we want SHARC and 24-bits audio, because have another project for SHARC. We probably shall port LAME C code , but it would be better to save time ... Kind regards Roman Rumian

You know about STA015, do you? Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com

yes, but we need multichannel encoder/decoder. Thank you. :-) Kind regards Roman Rumian
