Bobby,

I trained my ears using a set of CD's called Golden Ears, produced by Moulton Labs. Highly recommended! They are simple audio drills that you just listen to and test yourself with. The more you do it, the better you get at it. They're available from:

First, the audio spectrum is split into ten octaves, centered around 31 HZ, 63 HZ, 125 HZ, 250 HZ, 500 HZ, 1 KHZ, 2 KHZ, 4 KHZ, 8 KHZ and 16 KHZ. Pink noise is played, and one of those octaves is boosted or cut by 12dB, a substantial difference.

On subsequent drills and CD's you learn to detect those changes using music, then smaller 6dB changes, then the octaves are broken into thirds so you learn to focus in more closely etc. It's all very gradual and of course you just work at your own pace, do each drill set as many times as you want etc.

It also covers things like gradual volume changes over time, detecting distortion, compression, reverb, phasing etc.

Anyway, back to your comments about mixing versus mastering.
Yes, if done wrong or if the person mastering isn't careful, his processing can affect the overall mix balance of what he's working on. For example, compression might make quiet reverbs or delays in the mix more audible in the final master. That's definitely something to guard against.

You're right that the mind set for mixing is to make sure the various parts of the song blend well together, in terms of frequency balance, intelligibility of the lyrics, power of the drums, etc. but also things like timing (reverbs and delays), left to right stereo spread between the speakers, and perceived front to back depth.

Mastering is a more holistic mind set, where you are listening to the piece as a whole. You have to stop worrying about that perfect snare drum or guitar sound you were after, and just go for an overall pleasing spread of frequencies, making sure one song isn't markedly louder or softer than the one after or before it, etc.

Ideally, you want different people mixing and mastering, so the mastering guy can be objective and bring fresh ears to the project. But that isn't always possible, with everybody on such a tight budget nowadays. Usually one person is writing, recording, mixing, mastering, burning CDR's etc. *grin* and those are a lot of roles to fill.

If I were both mixing then mastering something, I would at least take a day or two off between the two steps, listen to other things to clean out my ears etc.
