What is an easy way to generate sets of precise sine waves? I like to generate (currently, slowly) separate sets of sine waves each consisting of a fundamental and 2 - 3 pseudo harmonics (really only justly-tuned perfect fifths, octaves, and a third--major or minor, depending upon the type of drone I want). The goal is to produce examples of justly-tuned chords that are easy to practice and teach with. And, sine waves are the easiest waveform for brass instruments to play along with. (This is very useful for orchestral brass instruction, and brass chamber ensemble exercises.) My current toolchain is clunky: XMMS --> ToneGen[erator] plug-in --> Hard Disk playback --> Audacity (to add an envelope to the front of each set). I would like to find a way to make this process more streamlined. I would love to be able to write scripts to do the dirty work. What program is suggested for replacing this toolchain? I think Csound can accomplish this. (Can this be accomplished with Audacity+Nyquist, too? Is there a plug-in that will play multiple frequencies at once?) Are there any favourite command line applications that can be used to produce multiple sine waves at once? Csound seems overly complex for this application, but I do not know of alternatives. Is there anything other than Csound? I just want to make sure I'm not overlooking a great specialized program before digging into Csound. Thanks a lot, Douglas Ward
