TinCan™ Audio

TinCan™ Audio aims to bring true, unfiltered, unprocessed audio to everyone, on any PC, or phone. How?
No DSP, No limits: Drivers provided here were carefully stripped of all DSPs, Limiters, and any sort of other sound processing.

Your device doesn't give out true audio. You probably use vendor drivers, which have many sound processing modules, that try to 'fix' sound of the internal speakers, while constantly modifying the audio waveform, thus what you hear out of your device is whatever manufacturer wants you to hear, not what the actual hardware is capable of.
Plus, they often limit the volume.. :0

Okay, well, what is the fix you give?? - Our drivers! They will be soon available.
