Indeed, but on a general note you can say to watch your Vu-meters (in your recording program) as closely as possible. You should stay the closest possible to 0 dB as possible, without crossing it.
If you go over the 0 dB level, you'll have clipping. Clipping is not wanted
But if you record too low, the sound level of the sample will not be high enough (!). If you wanna get it at the right level, you'll have to adjust the gain. But the problem is, if you increase volume of the sample, you'll also increase the background noises (hiss or hum most of the time). This reduces the quality dramatically.
So be sure you record in the best possible conditions. It's useless cleaning samples that have been badly recorded.
PS : a little habit of mine, and that you should do also. If you're software (like SF, DC adjust -> Calibrate in record window) has DC adjust, use it before starting any recording (with the source already plugged in, but not playing. For example if you record from the line input, be sure the line in is ready for recording, but nothing is playing through it. Adjust DC, and then you can start recording).
The DC adjust will correct any DC mismatches between your source(s) and soundcard. If there should be an offset, this can cause pops at the beginning and end of the sample. You can correct it afterwards, but like always, correcting the problem at the source is better than to correct it later.
