Hello Judi:
We have done the kind of batch editing you describe in your post. We're
using CoolEdit to do this. Note that CoolEdit was bought up by Adobe
awhile ago and is now marketed as "Audition." Folks tell me it looks
and performs very much the same, so I'll guess it will still have this
ability.
Below are instructions from the Help file. I include my own notes on
setting the Silence values but you would most likely have to experiment
a bit to find the values that work best for your audio file -
_Settings For Batch Auto Cue_
* Define Silence as less than -50dB, more than 140 msec
* Define Valid as more than -50dB, more than 5 msec
_Cue List
_A cue list is a list of time offsets, or locations defined within an
audio file or session. A cue can be either a point, specifying a cursor
position, or a range, specifying a selection. The Cue List is a floating
window, meaning you can click in the waveform on the main Cool Edit 2000
window (to define your cues) while leaving the Cue List window open. You
can also jump to a cue position in a waveform by double-clicking on the
cue in the list. Cue ranges can later be arranged in the Play List to be
played back in any order, with any number of loops. Cool Edit 2000
display Cues in temporal order, with the earliest cue position at the
top of the list.
To Add Cue press F8
_Batch_
Batch is used to separate or segment cues using one of two methods. You
can insert a specified amount of silence both before and after cues to
set them apart, or you can save the selected cues out to separate files.
First, in order to enable the Batch button, you will need to have one or
more Cues selected in the Cue List. After doing so, pressing the Batch
button will bring up a dialog allowing you to choose between Set Amount
Of Silence, or Save to Files.
_Set Amount Of Silence
_
Enter the number of seconds (see my notes) to enter silence before and
after each selected Cue. You may enter fractions, as in .52.
_Save to Files_
With this option, all Cues that were selected upon pressing Batch will
be saved out to separate files on your hard drive. Each file will be
named with the Filename Prefix you specify and an appended number, as in
Drum01, Drum02, etc. You can choose the directory to write the files to,
as well as the format they will be saved in.
With best wishes,
Mark

I have a faculty member who is trying to find software that will
automatically parse long audio files into shorter ones. What he wants
is to be able to somehow mark the audio file at certain "break
points" throughout, and then have the software divide that one file
into as many smaller files as he has marked, rename them and save
them automatically.
Any leads will be greatly appreciated - and (of course) the cheaper,
the better!
Thanks,
Judi

I do this with the $30 sharware Amadeus II (I think it is Macintosh only).
I suspect that many other programs can do it too. The free, cross-platform
Audacity might be worth a look.

Two pieces of software come to mind with this feature:
Amadeus II by HairerSoft (I have version 3.7.1 for the Mac, but Martin
Hairer is up to version 3.8.5 with it) will do this very easily. You just
click to insert "markers" along the file, then select "Split according to
Marks" from the Selection menu. You're prompted to name a folder to keep
the pieces in, and it names them consecutively and saves them there.
http://www.hairersoft.com/Amadeus.html
The price is $30 -- not free, but very reasonably priced for the number of
features it has, formats it reads (even AAC, mp4 and m4a) and writes, etc.
It also has some nice audio cleaning tools if you are transfering audio
from analog to digital.
I hightly recommend it!
If you have to have free, go with Audacity, which is made for all
platforms.
http://audacity.sourceforce.net
There's an extra step: you must add a "Label Track" to the project, then
insert "labels" at the points in the audio where you want them. Then you
can "Export Multiple" to save the pieces. You have options about what to
call the pieces, including track names or just sequential numbering with a
user-determined prefix.
If you get Audacity, make sure to get the LameLib so you can save as MP3.
You won't get quite the muscle you get with Amadeus, but Audacity has a
terrifi feature allowing you to record a track while listening to an
existing one, making it VERY helpful for languages.
Cheers,
Margo

Bias Peak (Mac only) does this (First create the regions, then Export
Regions). wwww.bias-inc.com It's not free or super cheap, but the last
time I checked they have a good educational discount.

Hi Judi,
For OSX, I use Freeverse (nee FeltTip Software)'s SoundStudio to do just this.
http://www.freeverse.com/soundstudio/
Use the M key to place split markers; then when done marking, use the Edit |
Split at Markers menu item to break up the file into pieces. Be sure to check
the box 'add file number before each new file name' or you loose the relative
order of the
files. If you're recording in AIFF (native) the files will be very large, so do
consider HD resources.
Looks like the price has gone up... it used to be $30; now the site says it's
$79 for v3.x. Version.2.4 works fine on Panther systems. You might be able to
find that one with a 15 day trial.

The program Audacity has a feature that will do what you are looking to
do.
if you import an audio file into Audacity, it will allow you set track
labels throughout the initial big audio file. Then it will allow you to
"export as multiple" and it will export the one large file into several
smaller files based on the track labels you set previously.
Audacity is also open source, so it's free. Just Google "audacity" and
you will get there website where you can download it and read the
instruction manual (which includes more detailed instructions on the
above process).
