I can't leave this site without writing a comment here... This has been BY FAR the BEST tutorial I've ever seen and the only one which has helped me to understand clearly the different parameters a compressor has. You explained it technically but so clear and without mistake. Thanks a lot for it, you did an excellent work!Too bad I couldn't hear the samples (maybe because it's from 2010 and the server took them down), but with the text it's been perfect already. :)
Absolutely incredible. I have been using compressors for a while - especially in live reinforcement. My experience and 'ear" training have taught me to use them in the various contexts your have explained and I have figured out which settings work best in each circumstance - but now I have a better understanding of WHY and that will help me greatly!Thanks so much!
Good Tutorial . A couple of questions :
1. When the signal goes above the threshold , the compressor acts and the compressed signal is still above the threshold . Am I correct ?2. When the first signal is above the threshold and the second signal is below the threshold . Release time is the time taken for the compressor to disengage when going from the first signal to the 2nd signal ?
1) yes. its is a compressor, not a limiter. Limiters will create a 'roof-ing' effect where no sound can go above the threshold, whereas a compresser will reduce the amount that the sound goes OVER the threshold2) yes again! it creates a flowing effect, so the sounds don't sound boxy
In the above Image , what does the line just below the threshold represent ?And what does the lowest line represent ?
That is a little bit of a confusing question vVgnesh!
There are 4 solid black horizontal lines, and 1 dotted red line:
- the dotted red line represents the threshold (a given dB measurement)
- the 4 black lines all represent 4 differing levels of signals from the input, which can be instruments or vocals or anything you are working with (also dB measurements)
- 1st signal = quiet
- 2nd signal = loud
- 3rd signal = moderate
- 4th signal = quiet
The vertical lines between each horizontal line are merely the change in signal volume.
The top graph represents no compression.
The bottom graph represents compression with 0 attack and 0 release.There are no dB measurements in the graph to reduce confusion.
Hi. Great explanation! Can you clarify something for me though please?If the attack is set to trigger with a longer response time than the actual length of the peak which is above the threshold, will the compressor simply miss that part out because by the time it is set to trigger the signal has already passed back to below the threshold and therefore it has nothing to compress? Thanks!
OMG this is the tutorial i was looking for!! Very concise and straight to the point.Thank you so so much for this <3
Hey! Do you mind if I use some of your knowledge and graphs in an upcoming e-book on mixing? I would credit you or your website.Thanks!
