Stereo Tool

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 52-004.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 52-004.exe

CHANGES:
- Added Multiband compressor Band Coupling matrix. You can use this to overrule the standard band coupling settings. Only available in Extreme Tweaker mode, awaiting responses to see how useful it it (if it is useful I'll move it to Expert mode).

TODO:
- Display FM lowpass frequency at bottom when FM output is used.
- Show warning when PNR is disabled due to changed settings.

PREVIOUS:
- Advanced Clipper: Advanced Bass Distortion Protection (ABDP): Drop in output when strongly clipping around 2600-4000 Hz is reduced.
- Advanced Clipper: ABDP: "Smooth Slide" slider added to make transition between deep bass (clipped) and less deep bass smoother. There used to be a drop upto the 2nd configured bass frequency, with this switch enabled the drop is smoothed (maximum at 1st configured bass freq, gone at 2nd). Result: Warmer, more open, less 'restrained' sound. But probably also a bit more intermodulation distortion. (which might be fixable by changing the frequencies a bit). (*)
- Added PNR Noise & Hum
- PNR analysis data is saved now

(*) If you don't hear the difference, try this: In ABDP, set the 2 bass frequency sliders both to 0. This will completely kill the bass. Now, turn the Smooth Slope setting on and off. The same effect is also present at normal settings, just less extreme.


Note: If you change the Latency or Quality setting or the number of audio channels, the PNR filter is turned off! Analysis is specific to those settings.

I'm very interested in the coupling feature. Could we get more of an explanation of that UI. Since the rows and columns aren't labeled, it's a tad tough for me to decipher. I'm guessing the idea is that you can couple any band to any other band, but the direction of that coupling also remains unclear.

There's not enough room.. I hoped it would be clear from how other pages work. Anyway...

Horizontally you see the settings that affect a single band. And you can indeed specify how strongly a band reacts to other bands. So, you can for example make the first 2 bands identical by setting the 4 sliders in the top left corner all to 100%.

You can also do other special things, for example you can make the highs respond to the lows to avoid intermodulation distortion (highs would be lowered in case of loud bass). I'm not sure how useful this is though.

Auto means that the values are filled in automatically, based on the Band Coupling and Highs and Lows freedom sliders.

Norm means that the values get normalized; if the total is > 100% then all values will be reduced to make the total 100%. If you turn Norm off you can get pretty extreme effects...

That helps a bit, but I need to know more. As you go from left to right on a particular row, are you setting the coupling for the next highest band? I think that makes sense as the very most upper-left control is already set at 100%, indicating that it is 100% coupled with itself (of course). So if I adjust the second from the left in the top row, I'm setting the coupling between band 1 and band 2, right? But which direction? Am I forcing band 2 to have as much gain as band 1, or vice versa. Obviously, the latter is more useful for most cases.

Also, I feel a bit challenged at the moment. I cannot locate the new advanced bass distortion control called "Smooth Slide". I'm sure I'm looking right past it, but a pointer to the screen it's on would be helpful.

Ok coupling in main windows need to be atleast 1% for matrix coupling to work.

Thanks! That would explain a lot.

is there a 64bit version standalone to hans?

Great thing this matrix!


Thanks Hans!

The sliders that adjust a band are located side-to-side, horizontally. So if you change any slider in the top row, you change the sound (volume) of band 1.
