Stereo Tool

I also noticed a bug in the VST version. Apparently, the zoom of the goniometer is not passed to the host. As soon as you open the plugin again, the zoom is reset. It's just a visual thing. With the waveform, saving the zoom already works. Perhaps this could then also be made available here.

If that's the case, then this is a problem for people using Stereo Tool VST in a "batch" situation where it is called as a new instance for every track. (For example, Foobar's "Convert").

Surely there must be some way for the VST to "self prime" with white noise or test tones or something set to -11 or -12 db?

I checked and this leveling issue at the start of tracks is present in Stereo Tool 8.54 final as well!

It is NOT present in Stereo Tool 8.34 final!

Strange I never noticed this before from 8.54 onwards.

Settings file export for version 34 final -> User_Default_f34.sts
Settings file export for version 54 final -> User_Default_f54.sts

If you load the User_Default_f34.sts into the latest beta 61, the problem is not present!

From Beta 61, I exported the settings which were imported from 8.34 Final, and compared the differences. Here they are:

[The other issue with the settings changing in Audacity are present in both 8.54 final and 8.34 final. Still not sure if this is something that can or should be fixed by Stereo Tool or by Audacity. (I'm guessing Audacity, as Foobar + foo_vst 0.9.0.3 have no problem recalling Stereo Tool's state.)]

I tried manually entering settings in Beta 61 to replicate the imported settings from 8.34, and was able to get the same result (no differences at start of track from first run of Stereo Tool).

Basically, the differences from User_Default_b61.sts are that both AutoEQ's are turned off, Low Level Boost is turned off, and Basstadizer is set to Legacy (i.e., Bass Boost instead of Basstadizer).

Turning on Basstadizer has no effect on the issue, so that should be eliminated.

Turning on Low Level Boost WITH or WITHOUT enabling Legacy mode results in the issue happening.

The issue also happens with ONE or BOTH of the AutoEQ's turned on, WITH or WITHOUT Legacy mode.

So this problem is tied to those three modules. If all three (AutoEQ, BassEQ, & Low Level Boost) are off, then the problem doesn't happen.

So what I am doing for now, and I guess will continue to do if this issue can't be fixed, is to use sox via batch file to append 30 seconds of "priming audio" at the beginning of tracks that I want to batch process with Stereo Tool. Then trim that off when done. A pain but if that's what it takes...

Just FYI, Hans is on his way back from NAB and will probably take a few days off.

Yup, I've slept in the plane, but by the time I arrived at home last night I hadn't seen an actual bed in over 53 hours. So I'm taking 2 days off back on Wednesday.

Hope NAB went great for you guys.

Welcome back.

I re-ran a bunch of tracks that I processed previously through Stereo Tool with the same settings, except that ~30 seconds (1,360,000 samples) of "priming audio" was appended to the beginning of each track, then removed after processing through Stereo Tool.

While in some cases the differences are minimal, in other cases the audible changes are quite night and day.

Here's a MasVis analysis:



The "not primed" tracks were from an older beta so some of the track differences past the first 20-25% are likely due to that (different peaks and such).

Sorry if I'm talking too much about this. Just want to give you as much info as I can.

Good morning to all,

Hans the French translation is available and if you wish, be integrated within the software itself instead of the old French translation.

Note: I have no feedback about my translation , but it is of good quality for those who are allergic to Shakespeare's language.
