Look-ahead compressor using StereoEnhancer

Using the chorus to delay the signal isn't perfect because the dry signal still exists. So I used StereoEnhancers instead. The StereoEnhancer works by delaying either the left or the right channel. Using two StereoEnhancers at equal "stereo width" and a minimixer, I created both delayed left and delayed right channels and mixed them together. Then I had to set the attack time of the compressor equal to the delays of the StereoEnhancers. The problem with that is that the Mono/Stereo knob is in percentages. So I used a very clicky sample of mine and recorded it as it went through the StereoEnhancer at different settings. These were my findings:   mono/stereo %   | offset (samples) | offset (ms) 0+             | 220           | 5.0 10             | 220           | 5.0 20             | 220           | 5.0 30             | 220           | 5.0 40             | 221           | 5.0 50             | 226           | 5.1 60             | 244           | 5.5 70             | 292           | 6.6 80             | 404           | 9.1 90             | 641           | 14.5 100            | 1102          | 25.0   Using a regression calculator at xuru.org, I fitted an equation to the data, where Y is the delay in ms and X is the Mono/Stereo %: Y=((2.741·10^(-2)X - 5.580·10^(-2))^6.865 + 220)/44100 If not divided by 44100, then the sample offset would be off by no more than 2 for each of the recorded values. This example is at 90% "stereo" with the observed 14.535 ms offset. For the first 16 bars, it alternates between look-ahead/non-look-ahead per 2 bars. Every 4 bars the compressor threshold is set to 70%, 60%, 50%, 40%, respectively. I tried to set the make-up gain so that each setting is at about the same perceived volume. Last 8 bars are uncompressed. Notice that the look-ahead doesn't have the transient at the kick drum. I set the volume so that the output clips at some of the peaks. Notice that the transient causes the non-look-ahead to clip much more. Template: http://www.audiotool.com/track/ohld56vpkxu3rj9vyvzgt2dodyh1kk/

Hey @Inavon , how did you make the table in this description? I remember Audiotool stripping space and stuffs

Can't believe it took you two years to reply

But it was some character that Audiotool doesn't treat as a space.

If you don't understand, then long story short: I found out how much the StereoEnhancer delays sound so that I could match that delay with the attack of the compressor to make it "look ahead."

Hehe. It's too hard for me indeed. Even I can't trust W|A on the graph
