Audio files with data values > 1.0?
Hi all-
I think a pretty simple question, but maddening difficult (for me at least) to search for on the Internet.
I am recording some audio rate envelopes ( to a file, and the data values range from, say, 0.0 to 50.0 rather than the usual -1.0 to 1.0.
So on playback, I'm getting clipping on values > 1.0. I'm having trouble locating exactly where my trouble is: [sfrecord~]? the AIFF file format? my audio editor?
Any hints, light shed, or suggestions (RTFM where?) would be greatly appreciated!
Thanks, Charles
As a small addendum: if I use the "open raw" message with [sfrecord~], the object will open a "Save..." dialog and the filename will be "snd.raw," but the "Format" drop-down menu at the bottom of the dialog is still set to "AIFF file." So it seems one inadvertently produces an AIFF file.
Not sure whether this is a bug in [sfrecord~] or something I'm missing about it's use...
its the bit depth/format.
you must export to 32 bit float.
float formats preserve the "over" values, integer formats clip.
-110
Thanks so much, Roman! That did the trick.
My next challenge is finding something that can visually edit an 8-channel file of this type. Looks like Amadeus and Audacity clip or normalize the resulting file to -1.0 to 1.0, and the MSP [buffer~] accommodates only 4 channels...
Best, Charles
