Stereo Tool

Yeah, the problem was my firewall it blocked the download.

BETA 761-015

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-015.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 61-015.exe
VST 32bit: http://www.stereotool.com/download/vst_ ... 61-015.dll

CHANGES:
- Made new Traditional Peak mode which behaves more like normal Peak.
- Added Lookahead, removes huge spikes at start of attack for fast attack times and reduces IMD.

The compressor should be complete now. Maybe some fine-tuning can still be done (esp. wrt Oil Temperature rise and fall speeds and Shape). Of course I still need to add feedback mode, ratio and side chains.

Oil temperature slider will make the time to reach the target level on attack roughly constant regardless of how big the jump in level is. Basically it will make the speed 'stay constant', similar to 'inertia' in the current SB and MB compressors. (But inertia has never worked on Attack and now it does). Note: I still need to make some changes (currently the oil can heat up instantly and that's not good, especially for release, so please don't use it for release; also the cooling down of the oil will affect the attack and release shape and I haven't implemented that yet in my model).


OLD CHANGES:
- Added lowpass filter to control signal to smooth out bad effects and remove distortion
- Added ITU-1770 mode to reduce pumping and improve level control
- Added Channel separation
- Rewrote all code
- Fixed Ratio
- Channels are not processed separately (wasn't the case before, and that was a bug)
- Fixed attenuation display
- Attack and Release times must be set to half the numbers of the previous beta's. Oil change speed must be doubled.
- Restored old Shape behavior from version 009
- Replaced 'Nonlinear Release' by 'Exponential Release', which works better and only needs 1 parameter. Use this to go up FASTER if you're down DEEPER.
- Added Ratio
- Added Feedback mode
- Fixed out-of-control behavior for certain extreme settings
- Fixed some more weird behavior things if the difference between Attack and Release is REALLY huge (behavior was bumpy and caused clicking sounds).
- Known issue: both Shape On settings must be enabled. I will probably remove them in the next build anyway so I'm not going to fix it.
Fixed a lot of bugs, will type the details here later. Oil Temperature is now in % and didn't work properly before. PLEASE LOAD THE DEFAULT SETTINGS for the new compressor or it will sound horrible.
Changed Attack Time, Release Time, Attack Speed Threshold, Release Speed Threshold to understandable values. Made 1.0 the 'standard' behavior for Shape.
- Added smoothing to oil temperature behavior for both attack and release.
Added Oil temperature behavior which was missing from my automatic (hydraulic) door model. Will explain below...
- Added another Peak mode slider in "New Singleband". The old one (from yesterday) works mainly on release, but in some cases the volume didn't go down fast enough on a loud sound. The new one works mainly on attack (higher value makes attack continue AFTER a peak.
- Changed Peak mode behavior in "New Singleband".
- New Singleband: Split Speed into Attack and Release Speed
- New Singleband: Made Attack and Release Speed Threshold relative to Speed - so you don't need to adjust it to change the shape.
- Added new Dequantizer filter to increase the bit depth of recordings.

TO DO:
Fix RDS time issue! viewtopic.php?f=6&t=5941&p=28209#p28209
Fix MB frequency band shift (10%, since 7.51 or 7.60)
Add RDS control via VST typedef VstIntPtr (VSTCALLBACK *AEffectDispatcherProc) (AEffect* effect, VstInt32 opcode, VstInt32 index, VstIntPtr value, void* ptr, float opt); for Bernd N
Clipper issues Leif / Wolf Stahl (probably the same thing)

Ok, I just found the cause of the multiband frequency shifting that started in version 7.51. I have 2 values in my software, one that indicates the maximum number of samples in a block of audio (4096), and another that indicates how much memory to allocate for each channel. That latter value used to be 4096+32, but I changed that (and I don't remember why, probably as a performance optimization) to 4096+512. And in this specific calculation I'm using the bigger value. So, the frequencies used to be 0.8% higher than they should be in versions upto 7.51, and since 7.51, they are 12.5% too high.

The good news is: The problem is solved. But, what do I do with existing presets? For the built-in ones, I can adjust the frequencies of the presets that were added or modified since version 7.51. But what about external presets? My current suggestion is to just load them as they are, because there are probably far more presets out there that were made with the 0.8% offset than with the 12.5% offset...

Yes, load as they are . If someone want to make them as before the change - he will makae it.
Because if you ajust them for this last thing , thay will change them and things will again shift on some side ... So
Leave them " as is". Everybody will make corrections.

As i understand right , with the fixed version the frequencies bands will shift -10% when loaded and user must readjust them if want the values before the last change now . right ?
If so, yes this is the right thing.

Hi Hans,

forums have been a bit dead lately so I thought I'd just suggest something. how do you think you'll go with adding some sort of punch filter? I understand there's burst protection and such, but do you think you could try something a little more advanced? like, it actually detects the punch and transients in all of the bands so you're not compressing the overall sound, rather just taking out the punch/transient in it? (not completely of course, just reducing it a lot)

Congratulations on your partnership with Telos Alliance btw. :^)

@face: This also compresses but what do you think? With a higher Threshold it would only affect the loudest sounds. (Sorry for the example music - but at least it's punchy)

Ohhhh, that sounds awesome! Was this done with your new compressor or something?
and the sample music is fine, haha.

Sounds great indeed For this sample it's maybe a bit too much, but it can sound more subtile I guess

Yup this is the new compressor. Used (faked) in multiband mode. Indeed a but much, among others because I had to process the bands separately so I had no idea what it would sound like until I combined them in CoolEdit.

Hmm.. The "uninst.exe" gets caught as Trojan.Generic.12891617 by F-Secure SAFE..
