Rockbox Ports are now being developed for various digital audio players!
The sound with the wma codec is great,it even has like surround sound,is it there a way to make better surround?
what if you output the bit stream through the regular headphone jack

but it is still possible to out put a "digital" signal through this analog output. the signal itself would still be output as analog but it would be a digital-ish signal thats being output. you'd just need to make/modify a decoder to decode this "digital" signal.

It's possible to output surround sound via headphones using just two channels. For example there's binaural recording, which records sound at the ears. Another example is some software which can downmix sound for headphones in a way which preserves 3D sense of direction. CyberLink PowerDVD and ffdshow can do this. It's not perfect but it's better than stereo. Ffdshow is open source and may have code which can be used in Rockbox.
