Why do I need a Clipper for Mastering?

[Hermetech Mastering]

So what can I achieve with a Mastering clipper?

I use one on most client projects to get a completely transparent gain lift, before hitting the final limiter. How much gain you can achieve is completely track dependent. You can clip very short, high frequency transients a fair bit before it becomes audible, whilst extended bass tones may not like any clipping at all, it's immediately audible.

On beat driven projects I can usually shave the top 1-2dB off of hats and/or snares transparently. I look at it like a little bit of free gain. If it ever becomes audible, I back it off.

I use StandardCLIP in Hard Clip mode with the highest quality settings and masses of oversampling, FWIW. I never use clipping as an effect.

I never clip the Capture DAC after the analogue chain, unless the client wants things very loud, as I prefer to capture a completely unclipped HD version for future-proofing/archival purposes.

Are you 'mastering' in the first place?

Use a clipper when you are not slamming a limiter with 6+ dB of gain reduction - IOW when you're preserving the dynamic range. The clipper will shave the highest peaks, depending on settings, then you can turn up the volume and have a track that is both loud and has dynamic range preserved.

Clippers have realtime waveform displays where you can see what you are doing. Of course, this can also be done in an audio editor, where you'll first use the stats tool to tell you what the highest peaks are, and then cut them off with the clipper. Then normalize to -0.3 dB or whatever value you want.

Of course any clipping should be 'invisible'. If you're introducing audible distortion, this is not 'mastering'.

This is for sources with sharp, fast peaks, of course. Not for something that stays at roughly the same level.

[excuse me please]

There's distortion and useful distortion.

You don't want either when you're at the mastering stage.

I'd argue that sometimes a little harmonic distortion is exactly what you need at the mastering stage.

Coming from a clipper? A clipper is static, you'd want to use dynamic harmonic distortion, no? There are dedicated tools for that.

BTW, correct me if I'm wrong, but a clipper is not introducing harmonic distortion at all.

I never said coming from a clipper, and I already stated I never use clipping as an effect. The subject was distortion and useful distortion, you said neither have a place in mastering, I said harmonic distortion is just what's needed in mastering sometimes. I get mine from the analogue chain. I have mastered thousands of tracks with a little extra harmonic distortion over the past decade or so. I stand by my previous statement.

Many people do use clipping as an effect, it's usually not hard clipping but a soft knee style. That can add various types of distortion, harmonic and inharmonic.

Any nonlinear modification of a waveform introduces harmonics. Some of it may be so brief or high-pitched as to be essentially inaudible, but it's there.
