Audio Delay Time Calculator
Calculate precise delay times and reverb settings synchronized to musical tempo
About this calculator
The Audio Delay Time Calculator helps musicians, producers, and sound engineers calculate precise delay times and reverb settings that perfectly sync with their musical tempo. By inputting your track's BPM (beats per minute), this tool automatically generates delay values in milliseconds for common note divisions like quarter notes, eighth notes, and dotted rhythms. This ensures your audio effects complement the music's natural groove rather than fighting against it, creating professional-sounding mixes with rhythmically coherent spatial effects.
How to use
Enter your song's BPM (beats per minute) into the calculator. The tool will instantly display delay times in milliseconds for various note divisions including whole notes, half notes, quarter notes, eighth notes, and their dotted and triplet variations. Simply copy the appropriate delay time value and input it into your DAW's delay plugin or reverb pre-delay setting.
Frequently asked questions
What BPM should I use if my song changes tempo?
Use the predominant tempo of your song, typically the chorus or main section BPM. For dramatic tempo changes, calculate delays for each section separately.
Which note division should I choose for delay effects?
Eighth note and dotted eighth note delays are most popular for vocals and leads. Quarter notes work well for rhythmic instruments and creating groove.
Can I use these values for reverb pre-delay settings?
Yes, these calculated delay times work perfectly for reverb pre-delay, helping create separation between the dry signal and reverb tail while maintaining tempo sync.
