Just want to kick this around before calling it a bug.
 
So.... some of the vocalists I record are less good at dynamic control than others. And for a few years now, I've been in the habit of using clip gain envelopes to control level before the vocal hits any compressors downstream. I don't like using compressors as the only level control; I prefer using them for what they do tonally, in the main.
 
Now, of course, volume envelopes happen after any effects, so switching to volume envelopes won't solve my problem.
 
In a recent project, I recorded a generally very good singer, but there was a lot of work to be done controlling her dynamics. I did this with clip gain envelopes as usual, and noticed, for the first time, a lot of zipper noise at each envelope change.
 
Is this a new bug in Platinum, or have I inadvertently done something I don't usually do?

I've got a workaround for now, which is to use volume automation, then send to a bus, and put the compressor on the bus, but that's a horribly convoluted solution to something that has always seemed to just work in the past.

It might be handy if you posted the zipper sound.

I did this fade using the clip gain envelope in SPLAT.3.

A better workaround would be to use a gain plugin and automate that instead. I use Blue Cat Audio's free gain suite for this, for exactly the same reason you use gain envelopes: so that the compressor has less to do. One advantage of a gain plugin is that you can change where it sits in the fx chain; it doesn't have to be at the top.

A blank FX chain would work too for adjusting volume before effects or populate an FX chain with the plug-ins for the track if using regular plug-ins instead of the ProChannel.

Do you slope the envelope changes, or are they abrupt changes where you drop 6dB immediately?

While I appreciate workarounds (I use VocalRider myself) that doesn't really answer the question. I haven't noticed it myself, I'll say that, but I never use clip envelopes as intensively as the OP seems to.

 I did this with clip gain envelopes as usual, and noticed, for the first time, a lot of zipper noise at each envelope change.

If there's a drastic level change within a clip, you won't get zipper noise but may get a click. Zipper noise is a series of clicks that happens during a linear change over time between values. I think we need a better idea of exactly what you're experiencing.

I was looking for a setting like StudioOne has, regarding resolution on automation sync - but did not find for Sonar.
 
Closest I found was AUD.INI settings

MixDezipperUsec=50
GapDezipperUsec=500
 
It's about fade ins for any changes in gain due to envelopes in project.
 
Did Cake forget to implement this for clip envelopes maybe?
 
Also looked for a node recuction thing for envelopes - but did not find any.
I remember seeing such operations in other daws at least.
But it might be there.

The problem isn't to do with the steepness of the automation slope; exactly the same slopes on volume don't cause the same problem.
 
I need to try to find some time to export examples and do screen shots, I think.
