Best Way To Increase Recorded Level? 2007-08-05 01:53:44 When doing digital recording, if your analog input level is very low, it makes sense to increase it. But this increase in volume in the analog domain must also increase the noise level. Alternatively, I guess you could simply record the very low analog signal and then normalize the recording digitally to 0 db after the fact. Has anyone actually compared these two approaches scientifically? Does one method introduce less noise than the other?
