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!

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...

float formats preserve the "over" values, integer formats clip.

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...
