The calculator computes these times from the tempo; it does not play them.
A reverb calculator that works from your tempo
A reverb time is a musical length, not a number pulled from a preset. Set the tempo once and the calculator turns every note value into milliseconds, so a pre-delay or a decay can be chosen by ear and written down exactly.
Every note length in milliseconds
At one tempo the calculator lists a whole note down to a 1/128, so a reverb time can be set to a musical value instead of a round number.
Straight, dotted and triplet readings
Each note value is shown three ways, so a dotted delay or a triplet tail is read off the table rather than worked out by hand.
Pre-delay, decay and their total
Pick the two note values you want and the calculator adds them up, which is the figure to enter as a total reverb time.
How it works
Set a reverb time in three steps
Enter the tempo
Type the tempo of the track, and every note value on the page is recalculated at that tempo.
Choose a pre-delay and a decay
Pick a note value for each one. Short values keep the reverb clear of the words; longer values let the tail bloom.
Copy the number you need
Read the pre-delay, the decay and the sum in milliseconds, and copy whichever one your reverb asks for.
Tempo, note values and milliseconds
The tempo range the calculator accepts, stepped one beat per minute at a time.
From a whole note down to a 1/128, each one listed at the tempo you set.
Every note value is shown straight, dotted and as a triplet, so no reading has to be estimated.
Times are given to a tenth of a millisecond, which is finer than any reverb field accepts.
Who reaches for a reverb calculator
Mixers setting a reverb time
Work out a pre-delay and a decay that sit inside the tempo of the track instead of guessing at the numbers.
Producers matching a delay to the beat
A delay that follows a note value stays in time with the music, and the table gives that value for every note length at your tempo.
Students learning what note values are worth
Read a dotted note or a triplet in milliseconds to see how the note values relate to one another at a single tempo.

Take the pre-delay and decay you settled on into the editor, or slow a track down and hear the space change.
