Remix Agent - Tempo and Beat Detection

This is a deprecated program function. The tempo of an audio object can be determined faster and more accurately in the object editor in the section Time/Pitch!

Remix Agent allows you to perform an analysis of the tempo of longer audio files, typically complete pieces of music from which a remix is to be created. There is an automatic detection of tempo and measure beginnings, which you can then edit manually. At the end you can split the object into individual objects of the length of a bar, match project tempo and object tempo, and write the tempo information to the audio file.

The audio material can have a length between 15 seconds and 10 minutes and should be rhythmic.

Start the Remix Agent via menu Object > Remix Agent… or from the context menu of objects.

Now follow the instructions in the dialog!

On the last page of the wizard, you decide what to do with the result of the beat analysis:

• Create remix objects: This option cuts the song bar by bar into individual objects that you can then reuse in the virtual project.

  Audio quantization: Objects are adjusted to a fixed project tempo, slight tempo fluctuations are corrected by object timestretching. With the option Use resampling for small corrections resampling is used instead for small corrections. Optionally, the loop mode can be activated for the objects.

  Note: If you subsequently change the tempo of the project, clearly audible pitch changes occur in the remix objects.

  Apply object tempo to arrangement: The project takes over the found BPM value.

  With the option Use crossfades the remix objects will get default crossfades. If Grouping is active, the remix objects are grouped. Optionally, you can save the tempo and bar information to the audio file and assign a new background colorto the objects.

• Adapt tempo: You can either apply the tempo of the analyzed audio to the project tempo or apply the project tempo to the tempo of the analyzed audio.

  • Apply arrangement tempo to object tempo: The object gets the tempo of the project. There are three options for this:

    • Use timestretching: With timestretching, the pitch remains constant, but sound changes occur due to timestretching.

    • Use resampling: Resampling changes the pitch but preserves the sound quality.

      Note: If you subsequently change the tempo of the project, clearly audible pitch changes occur.

    • Use audio quantization: Audio quantization applies tempo adjustments to the audio file.

    Save tempo & bar information: Also here you can additionally write the tempo and beat information into the audio file

  • Apply object tempo to arrangement tempo: As with the option Create remix objects the project takes over the determined tempo.

    • Change global settings: Use this option to set the project tempo to the determined value.

    • Adjust tempo map: Tempo markers are placed at the beat boundaries, with Use quarters at each beat. With Use bar pos. instead of tempo markers grid position markers are set instead of tempo markers.

• Save tempo and bar info: If this option is active, the tempo and bar information are saved in the audio file. The objects in the virtual project remain unchanged. Optionally, bar position markers can be set in the project at the bar beginnings (Create bar markers within current range or on each bar beat (Create quarter markers within current range).
