Is it possible to reduce the bit depth lower than 8 bit?  Or how do I reduce the bitrate properly after resampling to a lower bit depth?  At the moment I'm just shifting the samples to the desired bit depth.  I'm using the free r8brain version to downsample the samples of Amiga Protracker Modules to get more samples into the tiny memory of the Commodore C64 Homecomputer.

Reducing bit depth lower is certainly possible, but r8brain is not designed to do this.  Simple bit shift is not very good since this will cause truncation.  A special noise-shaped bit depth reduction could be much better, but this requires special programming which I'm not interested in.
