Tempo/Time Stretch

Top  Previous  Next

You can adjust the tempo or time stretch sounds.


Tempo settings on the Sound tab


hmtoggle_arrow1 Changing The Detected Tempo Of A Sound


You must be in "Adjust To Project Tempo" mode to change the detected tempo of a sound.  Click on the "Sound" tab on the bottom.




If the sound's detected tempo is wrong, you can adjust it via the "Detected Tempo" drop down control.


The original detected tempo will show up with an * next to it in case you need to restore it to the original detected tempo.



hmtoggle_arrow1 Detecting Tempo ( audio clips only )


The following information is for audio clips only.  If "Auto Beat Match" is on, all sounds longer than 30 seconds will be parsed and analyzed for a tempo.


Sounds longer than 30 seconds will show the actual beats in the Loop Editor.  This can be extremely useful as each beat will show a tempo at that beat point.  Most songs do not keep a constant beat and drift, in addition to having varying tempos, keys and time signatures.





Double or Halve the current tempo.  In some cases, the detected tempo is off by a factor of two.   To quickly adjust the tempo by two, click the "Double Or Half Tempo" button!

Average tempo button

Use the detected average tempo.  You can set the detected tempo to the average tempo within the active loop by clicking the "Use Average Tempo In Active Loop" button!


hmtoggle_arrow1 Setting A Specific Time Stretch


If you don't care about adhering to a tempo, you can adjust the length of a sound.  On the "Sound" tab, click the option to "Time Stretch By".  Now choose a value from 25% to 400%.


This can be useful for the following operations:


Fitting a sound effect in a longer or shorter time.

Syncing a sound to fit a video

Shortening a liability narration at the end of an audio ad. ;)

Lengthening a sound to hide any silence gaps.


You can visually time stretch a sound by using FlexAudio ™.
