Audio levels inside jack can well be beyond [-1:1] without any clipping. Inside jack its all float-numbers, they don't clip anywhere in the range of typical audio usage. Only the conversion to integers for the sound-device is the place where clipping happens. And at that place the convention is to map the range [-1:1] to whatever integers the bit-depth of the device has. Ardour's red markers "only" inform you that the signal will most likely clip when you send it to the hardware like that. Once there is a gain-reduction from an amplifier/volume-control or a limiter in the signal-chain, the results can be different. (It can also clip when ardour doesn't show a red symbol and levels below 0dB.) Have fun, Arnold
