48aa1e10d6 Use the high-shelf filter in place of low-pass 
They effectively both work to lower (or raise) high frequencies. However, the
high-shelf performs better when gain=1.

563f16dc2a Fix overflow issues when converting float to int 
32-bit floats can only reach between -16777215...+16777215 (25 bits) before it
starts losing whole-number accuracy. Some compiler optimizations may break
trying to multiply a float by 2147483647.0 when the result is given right to a
float parameter, causing it instead to multiply by the nearest representable
float value, 2147483648.0.

bf54de4984 Use less math to clamp floats to -1...+1 
The previous code could have issues as precision lowers. This should hopefully
work better while only using one if check instead of two.

1fb9311d82 Lock the device before calling aluHandleDisconnect 
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.

e2368eb960 Use an array to specify the offset for each channel of the device buffer
