    question about audio recording volume

    Hi,

    I have a question regarding the volume of the tracks I record.
    I use ubuntu 10.04, Jack and ardour to record songs on my acoustic guitar.

    Everything works well, but the volume of my tracks is a bit low.
    It should somehow be amplified.
    My question:
    should I do this by setting the output volume of my preamplifier to maximum,
    or should I amplify the audio data afterwards on my pc using specific software (I believe ardour has some functionality for it).

    Thanks in advance for any reply!

    Re: question about audio recording volume

    You should always try to get the level set appropriately going *into* the recording software. If you adjust it afterword, you will be adding noise into the resulting audio file.

    I would check that:
    1) Your input signal to the computer isn't too low (try just turning this up. Listen to the recording though-- if it gets "crunchy" sounding at loud moments you're probably overloading the computer's sound card, or "clipping", and should turn it back down a bit.)
    2) If you tried #1 and starting getting bad sounds, find the recording level of that input on the computer and turning it up. You don't want the level to be >= 100%, and you don't want it to be 1%. Try and get to a place where you can leave that control at 30-60% (or if the control goes above 100% -- say, to 400%-- set it at 100%).

    Have a look here for more information about how to set your levels:
    http://www.recordingreview.com/artic...ure/Page1.html
    I found that page with a quick google search, but at a glance it seems to explain the basics, and even specifically mentions acoustic guitars.

    Hope this helps,
    Matt
