Hi Brad,
to find the peak amplitude in a track, you can use the amplify effect dialog.
1. Select the audio in the track. (select the track, and then press j followed
by shift+k).
2. Open the amplify effect on the effect menu.
3. When this opens, then the value in the amplitude (db) edit box show the
amount of amplification needed so that the peak value would be maximum (0 db).
So if it was 15, then the peak in the track is 15db below maximum.
4. press esc to close the dialog without applying the effect.
Reading the timeline:
you can read the position of the cursor/selection start by pressing left
bracket when there's no playback. A dialog opens which give the time.
Similarly you can read the end of a selection by pressing right bracket when
there's no playback.
You appear to be using an old version of audacity, that is 1.3.14 alpha. Is
there any reason why you're not using the current version (2.0.5)?. As far as
I'm aware this should be ok on a mac.
David.

Hello all again,
does anyone know if it is possible for us blinkers, :-)
Visually impaired or blind people, to know the peak
amplitude for an existing track. Also is there a way to read
the time line. I believe Audacity shows these things
visually.
I am using Audacity 1.3.14
alpha on a macintosh system running OS X
lion.
TTFN,
Brad
