I've managed to hurt my ears twice over the past two days when using PD w/ headphones. Even at lowest system volumes, it seems that Terrible Things can happen. Are there any precautions that I can take to make it feel less like I'm taking my life into my hands when I have to use headphones?
Try making a [noise~] connected directly to a [dac~] and set the headphone volume so you can live with that. Nothing will ever be louder than that.
Hmm, I don't think that's actually true in all cases. On a MacBook Pro running Mac OS X, I've had the volume set to one above mute, but had massive feedback from LPC patches that were very very loud. [noise~] would be very comfortable at that volume setting. I think some platforms do the output mixing in the digital domain, so my min volume would be [*~ 0.01], so that this would still make a very loud sound:
[noise~] | [*~ 999999] | [*~ 0.01] (i.e. the Apple output mixing) |
In this particular case, the sound output actually gets shutdown entirely, so you have to reboot to get sound output again.
That make no sense. How can you have two sounds at the same level going into a mixer that come out at different levels? Or do you mean that a squealing sound is perceived to be louder than white noise? Maybe you could demonstrate with a patch?
