Hi all,

Today I implemented bandlimited wavetables in Pd vanilla using the idea behind mipmapping in OpenGL (ie, generate many filtered and downsampled versions of a source, use the most appropriate version(s) by a function of the derivative of the lookup index).

More info and full source (quick start tutorial: bl-example.pd):

https://gitorious.org/maximus/pd-bl

License: same as Pd vanilla.

Advantages over other implementations:

• Can generate wavetables from any waveform stored in a table.

Disadvantages:

• The higher harmonics are reduced compared to an optimal method.
