Audition track clipping/peaking in Multitrack

[patrickj85776599]

Hi.

I'm having sudden issues with my Audition in multitrack view.

When adding a edited clip which is limited to -0.1dB to Multitrack, it is clipping above 0.0dB.

This is despite this tracking running alone (no musicbeds etc underneath).

Why is this?

I've searched the forums etc, and found that it could be because the 'Preferences - Multitrack' settings was set to CUT on the left/right channel, but it is set to -3dB center and it only just started happening after this weekend. No issues before the weekend.

I hope you are able to assist in this matter.

Best regards,

Patrick

Problem number one here is that multi track can't clip at that level! Assuming that you are using it in its native 32-bit Floating Point mode, then it has a massive dynamic range - around about 1500dB (no that's not a misprint), and that any file put into it can be increased to that sort of level and then decreased again - without loss. Yes it sounds like magic, but in fact that's what Floating Point systems do inherently; they have a built-in scaling system, which is what the extra 8 bits are for (except that actually, it's 24 bits of signal information - the mantissa - and 7 bits of scaling - the exponent - and one sign bit).

That said, if you try to play back any sounds that go above 0dB in multi track, then yes they may sound clipped. The reason for that is that your sound device is inherently an integer-based system, so the Floating Point signals have to be converted to something 'finite' in order for you to hear them - and that of course can clip. But simply reducing the level of the signal with prevent you from hearing it.

I suspect that what you need to do is look carefully at the track controls and the mixer, and make sure that no additional gain either from trims or faders has made it into your settings; if I insert 0dB tone into multitrack with the panning set to -3dB center mode, then this comes back at exactly -3dB, as it should.

Hello SteveG.

I use 16bit, however, this issue suddently occured over the weekend without using the software.

AFter a chat with support, we reset the preferences etc and it's now back to normal.

When using multitrack it would 'lower' the volume to -3dB using a file that is 0.0dB or below that is.

So what made the crazy clipping before, I have no clue of.

Perhaps you would have an idea?

AFter resetting i unfortunately lost all favorites etc which took weeks to setup and alter to my needs. It's a bit of a shame to be honest.

You should have backed up all your customised settings before resetting Audition's Preferences. Perhaps add your voice for a Feature request to be easily able to back up Audition's settings.

I did rename the "adobe" folder to "adobe_old" and then had the program create a new "Adobe" folder afterwards. I have now moved all the shortcuts, favorites.xml files etc. to the new "Adobe - Audtition - 11.0" folder and it all seems to be working now.

Something in the old Preferences was messing up the multitrack audio levels for some reason, but with the new reset preferences it is now working.

What the issue was, again... I have no clue, but perhaps some of you may have an idea of it.

However, an easy backup tool would be fantastic... Goes for all Adobe software... How/where can I 'add my voice' to said feature?
