Stereo Tool

This would be awesome!

what does Steepness do ???..

thank you.

BETA601-011:
- Channels OK again
- Multiband 'steepness' behavior was completely wrong, fixed
- Multiband steepness effect displayed in Multiband output bars
- Multiband band 3 clipping disabled at latency 512 (caused very bad distortion)
- Flashes in output fixed (was indeed not a problem with the output itself, only in the display)
- New phase rotation and Multiband steepness settings saved to disk (both VST and INI)
- Quality and Latency are now part of preset files.

What remains:

* Multiband: Question: Is Steepness behavior ok?
* Loudness: QUESTION: The changed Punch behavior, is that good or bad?
- And I need to check how much the performance is impacted by the latency improvements.

Performance is 4% worse for 44.1 kHz input, 12% for 176.4 kHz input.
So I think I have some work to do before I release this...

Possible causes:
- More downsampling and upsampling overlap --> Can be fixed
- More difficult code for each sample --> have to look into this
So first I'll try to figure out which of these is causing it, then I'll try to fix it.

Yay no more artifacts in 4096

I'm getting a lot of artifacts when playing audio from the NLE, Sony Vegas 10.
Only at the settings 4096 though, at 2048 there is no problem at all. This only started with the new betas, 008 and on.
Right now my computer is being taxed a lot since I have sony vegas with over 10Gb of HD footage on the track and Adobe Lightroom open. Even so my idle cpu usage is around 25% (this is normal since I have folding@home running in the background, but its an idle process). The cpu usage barely goes above 35% when editing yet the audio stutters a lot and there are a lot of pops and clicks. Never had this issue before.

Question - is Stereo tool a mutli threaded application? Would changing the CPU affinity of the program through task manager affect it, I was thinking I'd force it to only run on the 3rd and 4th cores since sony vegas only uses cores 1 and 2 by default. (its only able to use more threads when rendering.)


-----FIXED
I had the BA live input settings too HQ. The input was set at 192 samples (the highest one) not 44.1khz.
Changed it back and put the buffers to default values, running smoothly now

Is that at all latencies? At 4096, I find beta 11 way better than ver 6.00. Or you comparing with a prior beta of 6.01?

BTW, I am not sure if I can see that...using VST.

1. Yes, measured at 4096... Way better = using less CPU? That's odd, because I also expected an increase (I just hoped it wouldn't be so much).
2. For normal output, at latency 4096, it should have no or very little effect. If you set it to 5% (the lowest possible setting), and/or reduce the latency or increase the input volume of Multiband, you should see it.

This has been asked, by dubstep, but I'll add my question in about what exactly is steepness doing?

I see a significant shading at the lowest band at 4096 when playing "Hot Tottie". Is this effect good, bad, or indifferent?

Edit: Switching to 1024 shows a similar effect with the 3rd band.

I've done a test and it should be possible to reduce the extra CPU load for high frequency content from +12% to below +5.5% (probably to around +4%). But I need to rewrite some things a bit.
