which is best suited dsp for 2ch to 7.1ch, dolby atmos converter/decoder.

Hi,

Please look in to the below ezone thread,

In this he is showing of converting Dolby Atmos content from Blue Ray.

But I want to convert a 2ch input like from bluetooth/Usb etc to 7.1 ch output.

Hi,

Analog Devices' SHARC® processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. With multiple products variants and price points, SHARC brings real-time floating-point processing performance to many applications where dynamic range is key. Latest products provide leading performance/power efficiency and advanced connectivity with an integrated ARM® core.

The latest ADSP-SC5xx processors are Multicore SHARC+ARM® SOC Delivers 24GFLOPS Performance at Under 2W for Advanced Real-Time Audio and Industrial Applications. You would find more information about these processors in the below link.
