Something to ponder over the holidays... I'm looking for some software to do octave-band analysis of a file with sampled audio data in it. Third- and twelfth-octave would be even better, but the immediate need is for whole octaves. I thought about trying to roll my own using FFT's, etc., but I'd rather not (he's going to say it) reinvent the wheel. Right now, the best way I have of doing this is playing the audio file back through a D/A into a Bruel & Kjaer real-time analyzer. So I can get the job done, but I sure would like to do it without the intermediate analog step. I'll take recommendations for freeware and payware. Send mail, I'll summarize unless I get flamed really bad. 8-) -- J. Porter Clark jpc@avdms8.msfc.nasa.gov or jpc@gaia.msfc.nasa.gov NASA/MSFC Flight Data Systems Branch
