Guys .. I agree that due to the settings you can straighten out the problem. But until it comes out only at the expense of narrowing the dynamic range of sound. It sounds flat and thin ... Not really .. but there is a flat sound. While the best quality is from Betta 28 May
I checked the updates since the May 28th version to see if I could explain this, but I would expect the opposite of what you're describing!
BETA
28 may version!
BETA2:
I just found a bug in the AGC that's both causing a mid/high frequency volume drop in the "Beyonce - Video Phone" track, and causing the volume to go down more for loud vocals in the Celine Dion song
Improvement!
- AGC behavior is changed around the place where the AGC started to reduce the volume before. Now it starts a lot earlier, but the effect grows smoothly. This does mean that input tracks around the configured target output level will come out a lot softer now! But at least all tracks at the same input level should now come out at the same output level. This also impacts the output RMS volumes: They are now about slightly more apart if the input level is different. (But I think the benefits outweigh this small disadvantage).
Should not change much. Around where compression starts it lowers the volume. But instead of suddenly starting to compress it now starts gradually
Changes are:
- No more bass added to band 2 (so it can now more easily separate from the lock to the band 1 level, Beyonce track is much better;
- level smoothing for input level near target output level (tracks around this input level with much dynamics came out far too soft before, now that has been greatly reduced).
BETA3:
I've uploaded a new version where you can control the stereo separation - at 100% it's identical to the previous version, at 0% the two channels are identical in volume (except when the difference gets too big and 'remove remaining peaks' starts to kick in).
Improvement!
BETA3A:
Bojcha has sent me a PM a few days ago about reducing the up speed when the current level and target level are close to each other.
Until now, the volume increment was very fast if the volume was very low, changing with an asymptote to 100%.
I've now changed this; instead of an asymptote that ends at 100%, the asymptote now ends at the new target volume level at the current position (so if the level doesn't change much, the volume stays almost the same).
Big improvement; sounds like Up Speed is lowered
Result:
- Volume of already compressed tracks is far more stable than before.
- Between voices, if there's not really a lot volume difference, the volume doesn't climb much, so it doesn't drop much when a new voice starts either.
- Relatively silent parts of tracks are not boosted as much as before.
- Big volume differences are handled similarly to before, which is good.
- And for the same track, the up speed is now identical regardless of the input volume (unless it's really low of course).
- For the same 'up speed' behavior, you might need to set 'up speed' slightly higher than before. (But I don't know if that's really necessary)
- Difference in dB ITU-1770 is a big higher now (unless you set 'up speed' slightly higher), but not that much (for the worst case situation, "Gimme Gimme Gimme" vs. very strongly compressed song, 1 channel, at default settings the difference increased from 2.1 to 2.8 dB; if you use 2 channels the difference is about 0.7 dB).
BETA004:
Fixed Loudness bug
BETA005:
Changed displaying up/down speed values
BETA006:
- Settings of 2nd AGC saved to disk
- Improved performance
BETA007:
- Replaced the slider. Set it to '1.00' equals setting 'target output level' for the 2nd AGC to the same level as the first in previous versions. (Setting it to 0.5 corresponds to setting it to half the target output level of the 1st, etc.)
- Previously, turning on 2 AGC's reduced the output level. Now there's a correction factor used, such that the COMBINED effect of both AGC's leads to the selected 'target output level'.
So, the 2nd AGC doesn't change the output level anymore, just the type of gain control that takes place.
Hm... Edit:
I just realized that the volume smoothing means, at low AGC output volume levels (strong attenuation), that the behavior is close to that of TWICE the input volume of before I switched to volume smoothing. Which means that the Up Speed works stronger, giving more compression-like effects.
NOT TRUE
But... The other change (smoothly going to the new target volume instead of going to volume '1') should fix that, and make it even better than before.
That would mean that it gets WORSE in BETA2, and then BETTER in BETA3A.
So this is also not true
This may also depend on the AGC input level - if there's not much attenuation taking place, and you have songs with much dynamics, I can imagine that they come out slightly flattened, even with the
