float WINAPI BASS_GetCPU();

Return value
The BASS CPU usage as a percentage of total CPU time.

Remarks
This includes the time taken to mix the MOD musics and sample streams (both file streams and user streams). It also includes the time taken by any user DSP functions. It does not include plain sample mixing which is done by the output device (hardware accelerated) or DirectSound (emulated). Audio CD playback requires no CPU usage.
