3894c580bf Use just the omnidirectional response for the compressor effect 
This is not the output compressor/limiter, but the EFX effect. Consequently, it
simply compresses the dynamic range around 1.0 (boosting samples below it by up
to double, reducing samples above it by as much as half). This is not intended
to prevent clipping on the output, but to instead reduce the range between
quiet sounds and loud sounds.

809f709ba6 Limit the normalized filter frequency to under half 
Nearing half, weird things can start happening with the filters' generated sine
and cosine values.

fd1458ce1b Always prepare the ALSA PCM handle before starting capture 
Draining the ALSA device via stopping puts it into a setup state, which
requires re-preparing before playback can start again. Preparing it prior to
the first start seems to cause no harm, so just always do it before starting.

35b78d55a4 Stop capture devices while closing 
In 'alcCaptureCloseDevice', check if the capture device is
running and stop it if necessary.
This fixes the case where the device data is deallocated while
a background thread is still running (Issue #199)
