Appendix A: Per Wave Processing
Some examples of the Per-Wave processing of relectro.
Assumed input signal (not very realistic, but good to show the actual
processing):
The example input consists of a full level pulse wave, followed by a -6dB
(half level) triangular wave, a -6dB pulse wave and finally a full level
triangular wave.
Compression and expansion works on any wave which is below 0 dB:
Compression raises the signal level of the two mid wave cycles (see
above), while Expansion does further reduce them:
