[chuck-users] Fwd: Automated batch conversion of ck files to WAV

[Leonard Ritter]

Thanks for the suggestions so far. These are interesting but they
require retrofitting scripts, so aren't universally compatible with
any ck ever written (which I hope you agree would be super super
helpful). Is there no solution that requires no change to the ck to be
converted?
