I know of a training manager who runs a radio course for adults and prefers Audition over Audacity for many reasons, including ease of use and more powerful features. Because Audacity is free, it is sometimes preferable for teaching purposes. However, whenever she gets the chance, she teaches them Audition while she gets to moan about the shortcomings of Audacity. The radio station crew always use Audition NEVER Audacity.
She sometimes gets frustrated when:
1). the main window cannot be resized vertically (i.e. zoomed in and out vertically, not just horizontally) so that more tracks can be seen at once (essential for large projects which have a large number of tracks)
2). creating a track from an .mp3 file is not intuitive
3). adding and removing tracks is not intuitive
4). difficult to do crossfades without seeing where the crossfade occurs (by way of curves), like you can in Audition
5). difficult to remove background hisses and hum completely when using the “noise removal” tool. Though one student suggested the use of the “vocal removal” tool instead so that the noise in a stereo track (which is the same in both channels) disappears.
6). when deleting a part of a track, Audacity does not allow one to bring back a part of it back (but not the whole thing, as you can do by an “undo”). For example in Audition, if you delete a section of audio, you can click and drag to reveal a part of the deleted audio.
7). the playback cursor can get very confusing. For instance, if you position the cursor, then playback a few seconds of audio, then stop, then decide to select a bit of audio from this stopped position, it is very difficult to do this because the selected audio will occur from where the cursor was positioned before the playback.
8). backing up a project file is definitely not intuitive, as you need to copy the “data” folder over as well as the .aup file
9). sometimes vertical red lines are seen throughout the audio tracks and it takes a while to work out that they are actually indicators of where the waveform has been clipped
Incorporate the above improvements into v2.0.6 of Audacity and she’ll be happy!
