Hi Tim, it's fairly straightforward to apply an effect to just part of the audio. To select some audio you have to select one or more tracks, and then the time range you want. When a track is the focus, pressing enter toggles whether the track is selected. To select a time range, you first move the cursor to either the start or the end of the range you want to select, and then you set the other end of the time range. There are several ways both of moving the cursor, and setting to other end of the time range. For example, during playback, you can press the left bracket key to move the cursor to where you want the time range to start, and then right bracket to set the end of the selected time range. If you need more info just post some more questions. In addition, there's more relevant info in the playback, moving the cursor, and selecting audio sections of this guide: http://vip.chowo.co.uk/wp-content/uploads/jaws/Audacity-2.0.6-Guide.html David.

The file is several hours long, and I just want to change certain portions of that file. Is there an easy way to do this in Audacity, or should I try Sound Forge, Sound Studio or GoldWave, or some other program? Thanks in advance for your help.
