Full Version: Determine Peak level in recording
Hydrogenaudio Forums > Hydrogenaudio Forum > General Audio

I'm trying to record some cassettes and I want to be able to determine the peak level on each side of the cassette so I can adjust the recording level.

I know EAC can determine the peak level but I would like to determine where that peak level is so I do not have to record the entire cassette side again.

Anyone know a program that will determine peak level and its location in the recording?

Isn't there maybe a possibility to do such adjustmets by EAC itself with its 'normalize' function (press F9, 'normalize')?
Something like: if minumum is lower than 50% or higher 95% set it to 80% ...!?

Perhaps wavegain makes You happier. It examines your wav-track for the maximum peak level ('wavegain.exe -c track.wav'). Of course wavegain has also frontend(s) and is able to apply certain changes too.

hello,

Why not record your source (cassettes) using 64 bits, then normalize / resample to 16 bits??

SoundForge 4.5 did it. It gave both the level and the position of the maximum sample. New versions should still do it.

@be026161, the first source of clipping is the ADC (analog input of the soundcard), it doesn't matter how much bits you use after.

Maybe I'm missing something, but, recording at low volume with a high bitdeph (then resample/normalize) is'nt the same as recording at max possible volume without clipping? (without having to find wether or not there is clipping?)

Ciao!

Yes, but as Pio2001 said, you will be limited by the weakest link. In this case this will be the ADC (in the soundcard). If the soundcard is 24bit it can be a solution, but finding the correct signal strength in advance is still better.

I think it was maybe overkill but I transferred it over to a machine with adobe audition which has a statistic function which seems to determine levels.
However each time I record the few seconds of audio where presumably that has the highest levels audition records a different level each time - one time it will be -1.67dB next it will be -.57dB, then recording it in EAC will result in -6dB!, So I can't figure out why the level should fluctuate that much, and obviously there is a big discrepancy between EAC & Audition.

If anyone has an explantion I would like to know

Yes, sorry, I didn't understand.
However, most soundcard clip first, and lower the volume after. Or if they don't clip, when you record at 24 bits, with the peak at -10 db, the ADC records at 24 bits with the peaks around 0 db, then the mixer applies the volume correction that you choose as recording level.
