Splicing Audio on Mac OS/X - Using iTunes

I have this 4 hour Audio and the most instructive segment is a 3 minutes slice that is located at the end of the Audio file.

And, so to allow easy and quick rendition, I am trying to splice that little segment.

There are a couple of avenues for doing so on Microsoft PC. But, at this very time, the most available computer I have is this Mac laptop.

So Goggled for help. And, picked up some good tips.

Help came in terms of toolsets and steps. The Toolsets are:

Apple – iTune
Apple – GarageBand

Apple – iTune

The steps are from https://discussions.apple.com/docs/DOC-3762

In iTune, listen to the song and note down the starting and ending time of the clip you will like to preserve
In the Library window, select the Audio and click on the menu items File / “Get Info”
Go to the “Options” tab, set the “Start Time” and “Stop Time” to match the start and stop marker you recorded earlier
Exit the “Get Info” window
Right-click on the track again in the main library window and select “Create new version/Create <> Version…”
Choose from the abridged output type
A new audio file is created.

iTunes / Library / Get Info / Options

General Preferences / Import Settings

As said earlier, an abridged output type is offered. To choose a different output type, one has to follow this path:

Menu Item – iTunes / Preferences
From the “General Preferences” window, click on the “Import Settings…” button
In the “Import Settings” window, in the “Import Using” drop-down , choose from these choices “AAC Encoder” / “AIFF Encoder” / “Apple Lossless Encoder” / “WAV Encoder” / “MP3 Encoder”.
A well written description of available Import types is available @ iTunes 10 for Mac: Choose import settings (http://support.apple.com/kb/PH1131?viewlocale=en_US)

Library / View Options

As we played with different output types, it became important to know which format we had saved a file. Towards that end, add File attributes as new columns to your Library view.

The steps are:
