Speed Multiplier
This sets how many times faster or slower the audio will play. For example, setting this to "2.000" will double the speed (and raise the pitch by one octave), or setting this to "0.500" will halve the playback speed (and lower the pitch by one octave).
Values between 0.010 (1/100th of the original speed) and 50.000 (50 times faster) are permitted. Values outside of this range will gray out the and buttons and cannot be applied.
Percent Change
If you know how much you want to change the speed of the audio in percent, enter that value here. You can also drag the slider to choose a Percent Change - the input box and the Speed Multiplier will update as you drag the slider.
Values between -99.000 % (equivalent to 1/100th of the original speed) and 4900.000 % (equivalent to 50 times faster) are permitted. Values outside of this range will gray out the and buttons and cannot be applied.
Examples:
- A change of +100 % (double speed) is the same as multiplying the speed (Speed Multiplier setting) by 2.
- A change of -50 % (half speed) is the same as multiplying the speed by 0.5.
- A change of +20 % is the same as multiplying the speed by 1.2.
- A change of -20 % is the same as multiplying the speed by 0.8
