decibels

In a previous post, i talked about the problems i have with clipping audio and levels.

In the attached image you now see, levels above 0dB of a 'normalised' audio, which is clipping on track and master level.

But it doesn't clip in an decent audio editor like izotope RX7.

No plugins used anywhere.

Some one an idea what is going on or what i'm doing wrong?

grtz

I think a bit more information is needed. For instance, is your project set for stereo or surround mode?

Note to self (everyone else please look away -- the note that follows is a reminder for mine eyes only): Figure out a clever, kick-booty signature that suggests I'm completely aware of how to properly and exhaustively party on and that I, in fact, engage in said act on a frequent and spontaneous basis.

Hi Turd. Thnx

Stereo.

Many DAWs and audio editing apps internally uses a 32 bit floating point architecture so clipping is typically not possible internally. The final output stage render still must be below 0.0 dBFS. Lossy file types often need a few more dB of headroom than a PCM file, and should be re-checked after encoding. AFAIK, Sound Forge, Acid and Vegas have always used 32 bit (floating) where as, other audio apps (Slo-tools) were non-floating 24 and in some cases16 bit.

Any chance you could make your raw files accessible?

May be inter-sample peaks?

Project sample rate and the sample rate of the file itself - do they match?
