Stereo Tool

Does't happen always.. i am tweaking preset, eu4ria, and reaload it via 'recent' when i want do discard settings... and it happens once out of 20-30 loading times. Preset uses 0.67 singleband thresh.

It needs about 3-5 seconds to settle down.

Yes it does, thanks for the fix.

I posted an update to Cobalt in the share section. It has declipper enabled.

Outstanding - thank you!

I have some funny stuff going on in BS412. Whatever I feed it, it slowly oscillates.

Playing ABBA's Gimme, gimme, gimme in 6.32:


Playing the same tune through 7.01 beta 3 with all settings the same:


A pure 440 Hz sine wave in 6.32, flat-line as expected:


But the sine wave too oscillates slowly in 7.01B3:


Thoughts?

Found it. I'll try to fix it asap, will give you a workaround for now.

The problem occurs in the following situation:
- Pre-emphasis enabled, but pre-emphasize output disabled
- Using FM sound card

What you can do for now:
- Use Normal output (or if you use Stereo Tool as a plugin, the audio coming through the host program)
- Enable pre-emhpasize output. But I suppose there is a reason why you don't.

Edit: BS412 issue should be fixed now. Problem was that the filter expected audio at 44.1 kHz but because 'direct sound card access' was enabled it got 176.4 kHz instead - 4 times as much data. Meaning that adjustments seemed to work at 1/4th of the actual response times.

Uh-ow. I just discovered that my VST version fix may have other unwanted effects. I'll have to restore some 'bad' code for performance reasons. I just hope that things will keep working... (If not I need to use a different implementation for VST and other interfaces).

Edit: Looking good. Tested in Winamp, Reaper, VST_Scanner, VST Host DSP, dBpoweramp, Sound Forge Pro.

Thanks for the swift response!
I'm running Stereo Tool standalone. The transmitter I run these settings on does pre-emphasize and stereo encoding on it's own.
But it doesn't handle strong highs too well, so I want to protect it from clipping. That's why I have enabled the FM processing.

Btw - you're in Sweden right? (Saw the URL in the RDS text... ) - I didn't know they are using BS412 there? (Actually I'm pretty sure they are not...)

I'm going to build a new version now, should be ready in about 1-2 hours.
