Stereo Tool

By the way, please load the new default settings for some of the sliders or it may work very strangely...

The "New Compressor" works on peaks, but by design (because it follows natural behavior) it controls on RMS level instead of peak level. Some people don't like this (it causes pumping on loud bass for example)... So I have just added a PEAK mode. Which kinda breaks the natural behavior design............. Building now.

BETA 761-003!

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-003.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 61-003.exe

CHANGES:
- Added Peak mode to "New Singleband".

OLD CHANGES:
- 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.

Problem with the lock-up the new singleband is not when using the Attack Speed itself only .
It`s represented when you set the Release Speed to the max and try to set Attack Speed to max - result is the singleband stops working. You cannot turn it back to work with set the default settings or to move them arround.

Any prediction for a Linux beta?

Yeah, the magic balls says: Install windows and try

BETA 761-004

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-004.exe

CHANGES:
- Changed Peak mode behavior in "New Singleband".

The "New Singleband" compressor by design functions as an RMS-level controller, rather than peak level. That's probably good for many things (the level at which it settles sounds much more constant than for peak mode). However, RMS-mode compression also tends to have some very annoying effects, mainly that bass sounds push the level down much further than other sounds, which causes pumping.

Now, this is actually the correct behavior. If you don't consider the fact that to our ears bass does not sound as loud as other sounds, in many cases bass is much louder than any other sound in a mix. Just look at a spectrum and you'll very often see that the bass is dozens of dB's louder than other sounds. The reason that you don't see it in the waveform is that bass usually has the shape of a sine wave, or even a flattened sine wave, while other sounds are moving in all directions (think of voices with asymmetry etc.).

Due to this, using RMS based compression causes severe pumping on loud bass sounds. Also, in many cases a mix on CD has been mixed to maintain a constant peak level, if you feed that through a peak based compressor almost nothing will happen, but an RMS based one will cause the volume to go up and down a lot.

To make a constant sound without pumping, I think using an RMS-based compressor with frequency weighing (basically, ignoring most of the bass) is the ideal solution. This may not keep the peak level constant though, which is also often needed.

So, I've now made a new slider that makes the compressor behave more peak-based. If you change the slider setting on a square wave, nothing will happen; if you use it on a sine wave, the level will drop by several dB when you increase the value of this new slider. For music which goes all over the place the effect is even bigger.

I will add a side chain soon.

OLD CHANGES:
- 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.

Building it takes too much time (because I need to perform a lot of manual actions to copy everything that's needed to a Linux VMware environment). I will have to look into it soon though because some issues have been reported in Ubuntu 13/14.

I confirm that latest linux gui version sometimes not works, but command line every time is ok (Debian, Ubuntu)

BETA 761-005

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-005.exe

CHANGES:
- 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.

Note: Initial results: For peak based behavior I'm now using 5.0 and 0.9800. These values can also affect attack and release behavior, espeically at very high settings (10.0+, 0.99+).
