[CM] /tmp full with SND files.

[e deleflie]

thanks Bill,

I've tried putting in a revert-sound after each re-sample ... but all
the temp files dont seem to be clearing themselves out any faster
(still fills up my hard drive).

I'm resampling a 4 channel file from 44100 to 48000 .... here's my
code .... maybe there's something wrong.... I dont remember what I was
thinking when I wrote it, but I seem to be re-sampling each channel
(of a 4 channel) independently ... could this be why I'm getting so
many tmp files?

                        ; resample
                        (display (format #f "Resampling from ~D to
48000 \n" (srate insound)))
                        (src-sound (/ (srate insound) 48000) 1.0 insound 0)
                        (revert-sound insound)
                        (src-sound (/ (srate insound) 48000) 1.0 insound 1)
                        (revert-sound insound)
                        (src-sound (/ (srate insound) 48000) 1.0 insound 2)
                        (revert-sound insound)
                        (if (= (channels insound) 4) (src-sound (/
(srate insound) 48000) 1.0 insound 3)
                                (revert-sound insound)
                        )

an 88MB 4 channel file writes these tmp files ... (which fill up my harddrive).
