A great need of a feature - AGC !

I'm using foobar2000 as an only music player on my PC. I'm really happy with it.
Replay Gain is a feature that I like very much, but it would be great if someday i could use in foobar AGC - Automatic Gain Control. This is a thing that controls volume of music in the realtime, increasing and decreasing the output singal strenght. You can find AGC in Alcatech BPM Studio or (even better) - OtsDJ, plus - you can hear AGC in action on every radio station... they are using it all the time.

So, for example, the newest LOTR soundtrack - Annie Lenox's "Into the west" is very silent at the beginning and then quite loud... yes i know that it should be like that, BUT i would like to have opportunity to make it more even without manually using mouse + sliders

Pleaaaaseeeee that would be great feature in Foobar
Looking for any comments (especially: "yeah, AGC will be in foobar 0.7.6 next week"

PS.
sorry, english isn't my native language... as you probably know already...

Hmm, I (think I) am currently doing something similar by replaygaining all my files, setting the replaygain preamp by +9 dB, and checking replaygain peak limiting. There's also the Advanced Limiter and Preamp DSPs; see if you can achieve something similar by playing around. As for true AGC itself, you gotta get someone more technical

The dynamics compressor included in the special package does what you want to do. You can download it seperately here.

gday...


just a wildshoot..

i think maybe Gabrys.. is thinking more like the ARC calculation
of waves L2.. (ozone also got it.. author: alexey lukin
the same man behind megamaxbit prosessor.)

if replaygain do "real" realtime.. i think i maybe have missed it.
when it regards the dynamics compressor..

to have a realy good "realtime" peak controller
in foobar should be a priorety.
the dynamic compressor do function alike..
but ain`t a 100% correct..

I'm afraid you're doing something quite different: you are 'normalizing' your tracks to a peak value of 1.0. No dynamics compression here.

What do you mean 'aint 100% correct'?

gday..

@garf..

thus. it works very precise on a constant
basis.. regardless of "tuning".. it do have some glitches of the
signal.. aka. some slip true.

I do not understand what you mean.

gday..

it seems to me that.. when using dynamics
and both internal peak VU. & a external peak meter ..
show some signals are bypassed..
it simply don`t "calculate" fast enough..

PS. don`t slapp me with a stick.. these are my findings only..
