Stereo Tool 6.31 is released! See the download page. Changes: AGC: Added a slider to protect against volume drops for loud voices. Loudness: Improved overall filtering (removed post ringing) at latency 4096, sound is cleaner in many ways (especially bass). Added some new controls for configuring it ("Time Spread") Loudness: Advanced Bass Distortion Protection: Improved bass clipper. Bass is now louder and clipped tighter Loudness: Added bass shaping. Adds harmonics to very low frequencies to make them sound louder Loudness: Allow turning highs intermodulation distortion off Loudness: Added "highs priority" slider, increasing this reduces high frequency intermodulation distortion but may cause some drops in other frequencies Loudness: Asymmetric bass reduction should not go below dynamic threshold Loudness: Reduced strictness, the high precision wasn't really useful Loudness: Split 'sensitivity' for bass clipper: Can now be configured separately for mids and highs. Result: more constant and higher bass level Loudness: Turned off old bass protection mechanisms in default settings. Caused artifacts, no longer needed Loudness: Reduced clipping strictness for mid-bass frequencies (lower CPU load) Loudness: Increased de-esser range, and it can be turned off now Loudness: Simplified clipping algorithm Stereo Boost disabled for lowest frequencies (below approx. 140 Hz) BS412 limiter: Show a warning and info when BS412 is enabled BS412 limiter: Fixed drops issue. Very brief drops can still occur but they are usually hardly noticeable BS412 limiter: Changed default values for more constant sound level Added and updated many presets Split values for Singleband, Singleband AGC style and BS412 Bug fix: Stereo Image was broken for latency 512 Bug fix: Icon now visible in stand alone version |

Congrats Hans, you are amazing. It's great you listen to the members with so many different listening preferences and are able to mold a product that gives such excellent quality for all.  [Bug in this final version?] I am getting a windows "Program Compatibility Assistant [If this program didn't install correctly, try reinstalling using settings that are compatible with this version of windows.]" error after installing and then closing either the standalone or the dsp (winamp). I downloaded the new installs several times to insure I had a clean copy and tried reinstalling different beta copies (non of which give me an error) but I still get the error every time with the final release version. I also tried rebooting my system and trying again. My system is: Windows x64 Ultimate, 12GB mem, Intel i7 970, DX58S0 MoBo, NVIDIA GTX 470 |

, i also got that message when I installed it, but I get it occasionally on Win 7 anyway so I didn't really pay attention. But if it doesn't occur with beta versions there must be something weird in this installer... Installation is ok though! Small and simple possible improvement: split sensitivity calculation for miss and highs. That way, if hoi have both the bass level won't drop further. Calf levels for mids and for mid/highs and use respective send settings. ( |

I like it. Nice improvement on high frequencies from version 6.21. |

Ok, I typed this on my phone, but I've been thinking about this a bit more and the following should really help with the bass (and take very little effort, a few hours max);- Instead of calculating the sensitivity based on mids + attenuated highs, I should probably calculate it based on mids and highs separately, and take the minimum of the two. That way, when both occur at the same time, the drop will be less bit than it currently is (and it doesn't need to be that big in that case). - I'm calculating sensitivity over a 4096 samples block. The calculation itself seems to be ok, but I can - after determining the level - check where I need to apply it, and where I don't. For example, if there are no mid/highs in half of the 4096 samples block, I can apply the protection only on the other half, leaving more bass in the end result. Simple calculation would be: 1. Calculate level as I do now (but without bottom limitation). 2. For each 256-sample block, calculate the RMS level. 3. Match these 256-sample RMS levels such that the reduction for the highest one is equal to the calculated level in step 1. 4. Smoothing filter on top of this which makes sure that each block that needs reduction gets reduced. 5. Later addition: Ignore start of a reduction block so the bass gets more punch. An additional advantage of this method is that if in a 4096-sample block there is only a brief moment where more bass clipping is required, the reduction at that brief moment will be less strong - which is good since you wouldn't be able to hear distortion in this case anyway. (Note to self: To keep in mind: I could also measure the amount of actual mid/highs distortion caused by bass instead of just the level ...). |

This release is, to me, perfect. I have tried a number os songs that used to be a problem, but now, they are sounding great. Hans, you and your suppport group have done a great job, AGAIN. What will you do next to improve on this? Thanks Al |

Wait a few hours and you'll see a new beta in which I made the bass sensitivity much better aware of when exactly the bass needs to be dropped - and it doesn't drop as much as it does in 6.31 if you have *both* mids and high.
