Sound Advice

Roger’s Rules of Compression by Roger Nichols

1: Don’t. I would rather spend the time to ride the solo or vocal to get a cleaner sound with no compression artifacts. I also prefer to manually remove pops and sibilance. You can use the volume automation in a DAW to eliminate vocal pops and sibilance problems by drawing a V-shaped notch at the center of the pop or ess. It does not have to be very wide, and it will work better than any automated de-esser or pop filter.

2: For the most transparent compression, use a ratio between 2:1 and 3:1. This will increase the apparent loudness of your vocal, but will not have that annoying pumping sound of badly adjusted compressor settings.

3: Don’t compress more than 4dB. Watch the gain reduction meter on the compressor. Adjust the input gain or threshold level until the reduction reads between 3 and 4dB, no more.

4: Use multiple compressors connected in a series if you need more than 4dB of compression. Set the attack and release settings differently and you will have more compression without sounding like you’re killing the vocalist.

5: Parallel compression works in some circumstances. You have the dry signal and the compressed signal – mix them together to get the sound you want. Make sure you compensate for any delay in the compressor to avoid phasing.
