Hi guys !!!

i jus shoot 3 tapes in Mini DV and the sound is too low !!!!!

i am editing in FCP, and i guess i can just raise the sound level on the timeline... but i don t want to lose quality or at list not too much !!
How can i fix it ?? or how much tolerance will have the sound before it saturate???
Thanks agains !!

Try duplicating the audio on multiple tracks... layering them will help increase the sound.

In theory isn't this the same as simply rasing the level of one track? Layering the same audio track over itself will double everything, including the signal noise.

You might want to try making a copy of your audio track(s) and running noise reduction filters on them before layering on top of the original sound.
 
True... but here's where it works great and where it doesn't... I might have assumed the wrong case:

Works Great: -- you forgot to set your audio dials on the camera and didn't monitor the meters. So the audio is very soft.

Works LESS than Great: -- Your subject is beyond the range of the microphone. THe mics were set at a normal recording level and you're trying to bring up the voice in the background.

Yes -- that would suck to do it to. I was just thinking we're talking about low gain.

we'll see...

duplicating a track can lead to phase issues. a good way to make a track louder when full volume isn't loud enough is to use the dynamics processor. it's in your audio filters. crank up the slider called master gain. this is a compressor so if you only want to use the gain feature with any compression, set the threshold and compression amount to 0.
 
Every method described here is just increasing the amplitude of the whole waveform.

You probably don't want to do that because you will be increasing signal and background noise as much as whatever you were trying to record.

FCP is not for audio editing, so I'm not sure if it has any kind of dynamic expander filter (it should if it has a compressor), but that is what you want to use.

It does the opposite of what a compressor does to the dynamic range of your sound. It will amplify the loudest parts and attenuate the softest.

However, if the recording is so bad that the noise level is close to the level of everything else, this will not work either, and I would suggest dubbing everything and hiring a foley artist ;)
