This directory contains two example programs of using the
SPKitWaveShaper class.

wshape is an amplifier program simulating a one-stage vacuum tube
amplifier.

wshape2 mimics a two-stage tube amplifier. It also contains
a Butterworth low-pass filter.

Both programs  may be used with the tranfer function files
fdata2.snd through fdata5.snd (fdata2.aiff through fdata5.aiff
for SGI) to produce a tube-like harmonic non-linear distortion
and a smooth overdrive distortion.

The transfer function files were generated using the UNIX spline(1G)
command. The input data for spline is stored in the files fdata2
through fdata5. The mktrfile command may be used to generate new
transfer function files. mktrfile works only under NEXTSTEP.
The usage is:

mktrfile fdata2 fdata2.snd
