Smallest Computer Capable of Running HQP Embedded?

However... with no upsampling

 

You can run basic PCM upsampling and DSD up to DSD64 on it. But let's say if you use HIfiberry DAC HD on it, in the nice small steel case and run upsampling to HIfiberry's max 192k PCM, it works perfectly fine as one box network connected DAC.

 

Something a bit bigger, I today tested my new Fitlet2 with E3950 CPU and it can do normal PCM upsampling and up to DSD256 with non-EC modulators (using -2s filters). This one is much more feasible for HQPlayer Embedded. E3950 CPUs can be found in various formfactors, such as Pico-ITX. There's now also newer generation equivalent SoC coming, but no hardware available yet due to chip shortages.

 

P.S. These, including Fitlet2 are available in automotive temperature range and WiFi, so if you want something nice, small and cool to run HQPlayer Embedded in a car....
