DANGEROUS BUG - Reafir shift boosts bands when shift-clicking (FIXED)

Robert Randolph · 10-22-2018, 04:23 PM

I thank you for reading my not-sensationalist title, as my ears are now ringing and I can't do any more work tonight.

Shift-clicking a point in ReaFIR causes the point, and connected point, to jump up or down in value.

In the .gif, I am shift-left-clicking points. Nothing more.

I just got blasted with +24db of 2khz because of this.

macOS 10.14, Retina screen if it matters.

(I still don't regret having auto-mute off)

One must be careful with sine waves.

Hah I was gonna say.

For future protection, always have a brickwall limiter running just above 0 db (like 3db or so) in your monitoring FX (save with default project for convenience).

Hmm not sure what that would accomplish, there's an implicit brickwall limiter at +0dBFS when you send to the hardware anyway?

It doesn't accomplish anything of course...

Only thing that'd work would be a limiter with a complex ratio that's negative (for the non-expanding variation of the term 'negative ratio') above 0dBFS...

AKA soft auto-mute.

(but you knew this already)

Perfect use for General Dynamics on the monitoring FX, I suppose. Normal playback:

And after adding a really loud sine wave:

The benefit is it stops the harmonic distortion when it hits the hardware. The 3db is to allow a little intentional overs (which can be pleasant). I think I misused the term brickwall, the kind of limiter I'm talking about is something more transparent and has a look-ahead possibly.

That's where the pain comes from, in my experience anyway, from all that saturation. There's loud and then there's loud+harsh.
