Mastering is a specialized skill; but if you want to be able to master your own material, the only way you’ll get good at it is to do it as much as possible. While we’d need a book to truly cover desktop mastering (I like Steve Turnidge’s Desktop Mastering book so much I endorsed it), these five essential tips will make your life a lot easier, regardless of your level of expertise.
Save all of a song’s plug-in processor settings as presets.After listening to the mastered version for a while, if you decide to make “just one more” slight tweak—and the odds are you will—it will be a lot easier if you can return to where you left off. (For analog processors, take a photo of the panel knob positions.)
Saving successive presets makes it easy to return to earlier version.
With loudness maximizers, never set the “ceiling” (maximum level) to 0dB. Some CD pressing plants will reject CDs if they consistently hit 0dB for more than a certain number of consecutive samples, as it’s assumed that indicates clipping. Furthermore, any additional editing—even just crossfading the song with another during the assembly process—could increase the level above 0. Don’t go above -0.1dB; -0.3dB is safer.
Setting an output ceiling (i.e., maximum output level) below 0dB will ensure that a CD duplicator doesn't think you've created a master with distortion. Typical values are 0.1dB to 0.5dB.
Halve that change. Even small changes can have a major impact—add one dB of boost to a stereo mix, and you’ve effectively added one dB of boost to every single track in that mix. If you’re fairly new to mastering, after making a change that sounds right, cut it in half. For example, if you boost 3dB at 5kHz, change it to 1.5dB. Live with the setting for a while to determine if you actually need more—you probably don’t.
Bass management for the vinyl revival. With vinyl, low frequencies must be centered and mono. iZotope Ozone has a multiband image widener, but pulling the bass range width fully negative collapses it to mono. Another option is to use a crossover to split off the bass range, convert it to mono, then mix it back with the other split.
Narrowing the bass frequencies can make a more "vinyl-friendly" recording. Here, the bass region (Band 1) has been narrowed to mono with a setting of -100.0\%.
The “magic” EQ frequencies. While there are no rules, problems involving the following frequencies crop up fairly regularly.
