Are the current version links in the first page updated?

No, sorry, will fix immediately!

edit: fixed

I have been trying this compresssor out and so far think it is quit good.

The look ahead seems to make it work smoothly.

I think I notice a slight bit of saturation type distortion even with saturation turned off.

The output volume and make up slider could be lessened in their effect. I think they are too sensitive and have too great of a range. There's some good potential for hearing and speaker damage here with an accidental twist of a knob.

The meters could be a bit more active and show a larger range.
I would prefer a graphic display of the wave and movable lines showing the threshold but that is a design decision and also may take up more cpu. I like the way GComp and some others handle this type of display and show a grayed area on the wave where the comp has cut back the level.

Are seperate controls(threshold etc) for the 2 bands a possability in the future, or are you planning to keep it simpler?

But I'm getting too picky/greedy.

The opto looks interesting. I haven't worked with it too much yet but it definitly has a different character.
On the solo clean guitar track I tried it on it seemed to be "bouncier" than the VCA.

Nice work so far. Thank you for this.

Thank you!

I seriously doubt that, unless you have very short attack/release times, because then the compressor itself starts behaving in a waveshapey fashion. When the saturation is turned off, it really shouldn't start saturating until you reach the +140dB area or something like that.

I agree upon reducing the range for the output knob, but not the make up slider. The make-up slider is meant for bringing the compressed signal into a normal dB range again, and the main reason that it can get "dangerous" atm is probably the out knobs range, not the make up ones.

More active as in faster / more responsive? The range I can easily change, what would be a suitable range in your opinion? I don't think I want to add the waveform thingy though

Maybe an "advanced" version later on

Hi Stefan!

I just tried the compressor: good work

I have a few suggestions: the first thing I noticed was the ratio control, which could use a log scale IMO. Anything over about 8:1 is normally considered limiting, so at the moment it is hard to dial up anything else! I would prefer it to have a scale in which 12 o-clock was approx 4:1 and, I don't actually think it needs to go any higher than about 20:1 .. a ratio of infinty:1 is only really needed for last-in-the-chain brick-wall mastering limters IMO.

I think the cross-over frequency should also have a log scale..

And how about a bypass button on the front panel that bypasses the gain stage but not the delay to avoid glitching?

And.. how about an oversampled gain stage?

Actually, I would really like to see an oversampled stream multiply module in SM, for high quality ring modulation as well as this type of thing..

Ok, I agree upon almost everything. I will keep the range all the way to inf:1 though, but a log scale will make it way easier to handle

Oversampling will most likely have to wait until we have a generalized way of doing it.

Not too long I hope

I'm known as "platinumears" on the SM forum btw, in case you hadn't realised!

I already knew

The new compressor has more features but takes more cpu...

stefancrs · Post by **stefancrs** » Mon May 15, 2006 4:30 pm

How much more and what CPU/host? Here it uses about 0.5% more (Athlon 64) or less (both show a 5% CPU usage in Podium)

sinkmusic · Post by **sinkmusic** » Mon May 15, 2006 5:16 pm

7-8% in Live on a laptop, asus l5c, p4 2,6ghz, 512 ram.
If i remembe well, previous version was 3 or 4%

stefancrs · Post by **stefancrs** » Mon May 15, 2006 5:19 pm

That doesn't seem about right...

Do you get the same CPU readout in both VCA and opto mode?

Has anyone mentioned sidechaining yet? I'm sure they have. Let me mention it again: Sidechaining!!

It's so great.

stefancrs · Post by **stefancrs** » Tue May 16, 2006 7:09 pm

Lalo did back in the old days... I'll try and see if I can incorporate it in some decent manner, it will probably be a third mode then (VCA/opto/sidechain). Don't expect it in the next release though

bengeorge · Post by **bengeorge** » Tue May 16, 2006 7:21 pm

I don't think it would be that hard, just have the extra input and a switch to select sidechain mode.

Awesome compressor by the way, lots of character.
