Ok, thus if it there's a clipping it is "after" Pd (or at the I/O API level). Thanks for the confirmation.

A simple test on Linux with JACK shows that Pd doesn't clip audio that exceeds -1 to 1: https://mathr.co.uk/tmp/jack-no-clip.png screenshot Other API may be different, and the driver may clip (or do other dynamics processing) before sending to the hardware. >> Von: "Nicolas Danet" <nicolas.da...@free.fr> >> In the "A02.amplitude.pd" example it is claimed that: >> >> "Amplitudes of audio signals can have any reasonable range, but when you >> output a signal via the dac~ object, the samples should range between -1 and >> +1.

I tested with a less current version: $ pd -version Pd-0.47.1 ("") compiled for Debian (0.47.1-3) on 2016/11/28 at 20:56:10 UTC Claude -- https://mathr.co.uk _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
