(1) 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.

I suspect that many other programs can do it too. The free, cross-platform Audacity might be worth a look.

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.

Bob Majors Language Learning Center University of Washington (6) 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.

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).
