If your soundcard supports stereo playback, RealSpectrum can work in stereo mode enabling some amazing effects. 256-steps stereo panning. Each channel can be panned independently to 256 positions ranging from extreme left to extreme right.

Beeper vs AY loudness balancement. RealSpectrum emulates Covox, Stereo Covox, Soundrive and Music Machine using a 4 x 8-bit stereo interpolated digital mixer for high quality. AY-LPT circuit support. The CPU emulation is ultra-accurate, fruit of our own investigations into the Z80 architecture. Our Z80 core is extremely stable and almost undistinguishable from the real chip.
