The Delay Time Calculator (DTC) calculates both delay times in milliseconds and frequency modulation values in Hertz for either a song tempo in 'beats per minute', for a frequency value, or for a measure duration and signature.

There are many uses for this utility, including calculation of

• Pre-delay times for reverbs.
• Delay times for generic delay effects without tempo sync.
• Fequency modulation values that match a song tempo, which are especially useful when used with low-frequency oscillators (LFOs), for example on synths or filters, or on modulation effects like chorus, flanger, phaser, vibrato, tremolo, etc.
