Working in the Timeline
To transpose a tagged audio clip, do one of the following:
m
Select the clip, choose Clip > Transpose, then choose the number of semitones by
which you want to transpose the clip up or down.
m
Control-click the clip in the Timeline, choose Transpose from the shortcut menu, then
choose the number of semitones by which you want to transpose the clip up or down.
When Soundtrack matches audio clips to the project key, it transposes the clips using
the smallest appropriate interval. For instance, when matching a clip recorded in the
key of D with a project in the key of A, the clip is transposed down five semitones (–5)
rather than being transposed up seven semitones (+7), although either transposition
would put the clip in the project key.
Transposing clips can lead to undesirable results, such as when the sound of the
instrument recorded in the clip is moved outside its natural range. If the sound of a clip
changes in an unsatisfactory way, you can try transposing the clip up or down by an
octave (12 semitones) and see if you like the result better.
The following table shows the correspondence between semitones and musical
intervals for transposing clips:
