BETA016:
It's been a while. I've been doing lots of things (following up things from the IBC, testing hardware), but I've also been busy optimizing the performance. This new version should behave roughly the same on older systems, but run much faster on newer (i3/5/7) systems. Stokkemask filter (when Faster is enabled, default settings) is a lot more efficient.
Windows 32 bit:

Winamp DSP: http://www.stereotool.com/download/dsp_ ... 51-016.exe
CHANGES:
- 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...).
TO DO:
- Improve web interface further.
- Fix RDS clock on 64 bit
- Add presets
OLDER:
- 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.
