+# this is a script for generating a wavetable file 
+# a wavetable file consists of a one-dimensional array of samples representing one period of a waveform
+# metadata includes: 
+#    - file version (for program compatibility)
+#    - binary format (float, double, int32, etc.)
+#    - domain (normal is a phase from x=0 to x=2pi)
+#    - range (depending on datatypes, e.g. float=[-1,1], int32=[-2^15, 2^15-1])
+#    - waveform RMS (for loudness normalization)
+# the synth program uses the filename, not any metadata
+
+# this script uses the function defined in example_wavetable.py to calculate samples
+# if you want a custom wavetable, copy/edit/modify the example function (desmos is great for brainstorming)
