Synchronizing audio and the project tempo
AudioSnap (Producer and Studio only)
How does it work?
Each audio clip has an internal tempo map, which makes it possible to synchronize the audio clip
with the project’s global tempo map (see “Editing a clip’s tempo map” on page 613).
SONAR automatically creates a tempo map for each audio clip. In some cases, SONAR can detect
the wrong tempo. For example, SONAR might detect a tempo of 120 BPM when the actual tempo is
240 BPM, or a beat may be mapped to the wrong transient. You can easily remap the tempo map, if
necessary.
You should make sure a clip’s internal tempo map is correct before using any of the tempo-related
commands in the AudioSnap palette. For details, see “Editing a clip’s tempo map” on page 613.
To sync the project tempo to an audio clip
1. Select the audio clip(s) that has the desired tempo map.
2. Press A to open the AudioSnap palette.
3. Click the Set Project Tempo From Clip button on the AudioSnap palette.
The clip tempo map is copied to the project tempo map so the tempo maps are identical.
If you need to align the project tempo with freely played MIDI notes, see “To sync the project
tempo to freely played MIDI” on page 728.
To sync an audio clip to the project tempo
1. Select the audio clip(s) that you want to follow the project tempo.
2. Press A to open the AudioSnap palette.
3. Click the Clip Follows Project Tempo button on the AudioSnap palette.
The clip is synchronized to the project’s tempo map.
Note 1: The Set Project Tempo From Clip drop-down list lets you specify at which resolution
the clip’s tempo map should be copied to the project tempo. The options are as follows:
• Beats
• Measures (default)
• Clip
Note 2: If multiple audio clips have their Clip Timebase property set to Musical, changing the
project tempo will affect the relative positions of the audio clips. When using the Set Project
Tempo from Clip command, SONAR will offer to convert the timebase to Absolute.
Note: If the audio clip does not play back at the expected tempo, the clip might not have an
accurate internal tempo map. For details about editing a clip’s tempo map, see “Editing a clip’s
tempo map” on page 613.
