Stereo Tool

Sorry for not writing the last weeks but am very busy . The 64 bit version is faster than the 32 bit and both are faster than the last release.

Question to people who had crashes. Can you please try the following?
1. Enable Extreme Tweaker mode
2. Under "Configuration", press the "TEST ERROR (CRASH)" button
3. Then please post the address that's reported.

Reason: I'm looking at the locations of reported errors and they make no sense. I think there may be an offset that might be different on different pc's. (have seen that before). But I need to know the offset so I can calculate the address of the error.

Edit: Confirmed, I see completely different addresses on different systems. I'll see if I can add something in future versions to automatically include some offset value. But I can't do it before I have fixed the reported crashes - any change in the code makes the addresses invalid.

Test made ST 7.50 ​​(I'm not using ASIO, not if it has to do with the problem)
The latest beta is inutlizable here. from the moment it opens starts generating the exceptions previously attached. (and does not play any sound)

Exception in: GUI Event Handler (Exception 0xc0000005 at address 0x5f8a8a, read/write=0, r/w location=0x1)
Restarting: NO

Hm, wow. Turns out that with the code generated with the new compiler the addresses move every time you start Stereo Tool! With the old one you always get the same address... This makes it nearly impossible to find the location of the crash based on an address

I think I did find the cause of Nelson c's FFFFFFFF errors though. At the very least I found something that could cause this. And solved it. More later today...

On older pc's there's no performance gain - so that's still useful. Please don't kill me!

Crashes in stand alone version reported by Powersound and nelson_c should be fixed now. Will now check the DSP errors. Build will follow later today.

BETA018:

Hopefully the crashes are fixed now. Also the CPU load of the Stokkemask filter is reduced a bit more (in Faster mode). At least on my pc... might be different on pc's with less CPU cache.

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 51-018.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 51-018.exe

Windows 64 bit:
http://www.stereotool.com/download/ster ... 51-018.exe (NOTE: NOT AN INSTALLER - this is the executable).

CHANGES:

TO DO:
- Improve web interface further.
- Fix RDS clock on 64 bit
- Add presets


OLDER:
- Added faster processing paths for SSE3, SSE4.1/2, AXV and AVX2.
- Optimized Stokkemask filter (so far only in Faster mode, will optimize the other modes later). Filtering is slightly less good, although I don't see it in the measurement results.
- Changed band steepness minimum values for multiband from 6 to 3 dB/octave. (Ooh. I hope i changed MB and not ND...).
- Added a bunch of new presets. Some need to be updated again. And the Jeroen Platenkamp HvZ mod version is currently identical to the original.
- Web interface drawing of equalizer fixed
- Crash when loading some presets fixed
- Bug fix: Prelimiter acted up at certain latency settings.
- Web interface dragging fixed.
- Bug that caused sliders and top menu to stop working fixed.
- Calculation of FM MPX left/right peaks was wrong when using Composite LIMITER, fixed.
- Made left/right display green (with above 100% yellow) as suggested by mpex2006km.
- Improved web interface a lot more ("1000" is gone, more displays are working, right part of display auto-scales to device width)
- Fix MPX Power calculator
- Fix resetting of tilt calibration when loading a preset
- Add volume meters which show > 100% modulation for IBC demo
- Bug fix: Single-channel file in plugin version caused crashes when using the composite clipper.
- Compressor/limiters: Moved limiter before compressor. This slows down the attack speed when limiting occurs, which gives a more stable sound.
- Improved web interface. (Not yet finished).
- There's some weird sound audible when you enable 'DIFFERENCE' mode. Even if nothing happens. This means that the audio is somehow damaged. It's worse at lower latency settings. FIXED
- Make highs clipping level configurable. DONE
- Fix composite clipper mode. DONE
- See a few posts up. I've now added 2 sliders that can be used to reduce the effect when there's not clearly a tone present. Tones only reduces the effect when there isn't a single tone that clearly sticks out - basically it checks how loud the strongest band is vs. the total of all bands, and adjusts the effect based on the result of that calculation. Since there are almost always also other tones present, setting this too high will even reduce tones that do clearly stick out. Tones threshold can be used to turn the filter off completely if there isn't a single tone that clearly sticks out (it makes the slope of the Tones only effect steeper).
- Changed some things back to how they were in version 005 - Bojcha reported (and I confirmed) some weird artifacts in version 006. If you enable METHOD2 you get the 006 behavior, that's for my own tests and I will remove METHOD2 later.
- Added Smother filter. The higher you set it, the more it will ONLY affect the loudest sounds. If you have multiple loud tones (for example a bass and a loud voice), setting this very high might cause only one of the two to be effected - setting it very low will affect everything though.
- Added multiband pre-limiter/phase optimizer to the Advanced Clipper.
- Trying a different multiband limiter in the Advanced Clipper. This time without phase optimizer. I'm very curious which version you guys prefer!

Using lower limiting levels lowers the loudest sounds in the mix. Since bass is often the loudest sound it tends to reduce bass more than other sounds.

GUI bug with the MPX power level meter is still there.
Disabling FM transmitter from the checkbox and enabling the AM transmitter from the checkbox is causing the meter to appear in strange condition. I don`t know if this meter must appear at all in this condition.

Hmm... this stand alone version don't start with my win7 64bit i5..
Error windows message box "ST stop working.." , I can't show all screen because language is not English.

But you can always translate it right? Pozdrowienia

I will try to test it on my "new" system today, which is also i5 (2-nd gen) and Win7 x64.
I did some clean up recently and I no longer have my E2220 system. So when I get home and have some time, I will test it on Athlon II also.
