I'm having trouble figuring out which of the two is better for me to create a vinyl recording at the highest volume without clipping.

I capture a record via my preamp into Audacity, and I get what seem to be relatively low levels even though I make sure the levels are right when I record (Peak: -6.4db, RMS -24.6db). Am I doing something wrong? Or are those levels right? These recordings don't seem as loud as mastered CDs.

Anyway, to get the most accurate sound possible, should I use normalize or just increase the volume? If normalizing makes everything sound the same at a peak level, doesn't that completely screw with the dynamic range of the music?

Thanks!

Record with Audacity.
Go to Normalize, and check ONLY remove DC offset (or DC offset correction). Uncheck normalize track to ____dB

Then after that, Amplify. It'll automatically find the right amount to amplify to get your highest peak to 0dB.

If you use normalize, then all the tracks (if you record each track separately) will lose the intentional volume differences and they will appear/sound as if they're the same loudness.

As will also occur as a result of your suggestion to amplify to 0 dB, the only difference being that this option is free of the otherís idiosyncrasy whereby it treats both channels separately (as I noted in the past and as is still the case according to DVDDoug).

??

If you have multiple tracks (and you select all of them) and amplify them all at the same time, it will raise all of the tracks by the same amount until the highest peak in any one of the tracks meets 0dB.

Not sure what you mean. Normalize raises all of the tracks by different amounts so that the highest peak in each individual track meets 0dB.

I'm using Audacity 1.3.13
