One of the several variables that I need to get right is the audio level. I
understand I need to get this within a few dB of -20db or so relative to the
overload point of my sound card.
The question is how do I find that point?
On my old computer, I had 'meters' associated with the volume controls
comprising a bar graph which was green up to a point when it became red. At
least this showed what may be the overload point. My present computer does
not have these graphs.
I make the recordings using Cool Edit, and although this has a dB scale, it is
difficult to determine what this is relative to.
Is there an easy way to set the audio level to optimum? Some software
perhaps?
Another related question. The last few recordings I made of Valerio, had very
strong QRN and intermittent local electrical noise peaks, several tens of dB
above his signal. Should I ignore these when setting the level?
