I have read that in pure data if you mess with audio signal it can destoy your audio hardware (and even your ears !!) because the signal is not bound to -1/+1 so I wonder if there is any simple tip, abstract, external that handle dac~ and protect from hardware damage ?
The physical dac in the soundcard is incapable of going beyond +-1, it just clips the sound. It might not sound nice but it's perfectly safe unless you have an amplifier that's too powerful for your speakers or your ears...
