Delay Time Calculator
Delay Time calculator can be used to sync your reverb and delay times to the tempo of your song. Some people also use it to time their percussion instruments to begin and end (ring out) in time with their song.
Use the delay calculator to make a subtle delay mixed just under a reverb (using a delay calculator derived time). Mute the delay – Notice a difference?
I like to mix and match sometimes triplets with regular note times, sometimes using reverb for one and delay for the other. Try applying 3 different times from the delay calculator to a LCR delay.
Delay calculator time – Applied Usage
I also suggest using the time calculated from the delay calculator to be used as the entire time… Say you use the delay calculator and calculate a time of 600ms from a BPM of 100. You decide to apply this to a reverb, and use a predelay of 15ms. You got 15ms from taking 600ms derived from your delay calculator and divide by 40 or you notice that 1/16 note is 150ms and reduce by a factor of 10. I would now subtract 15 from 600 resulting in 585. Predelay is 15ms, reverb time is 585ms, and total reverb time including predelay is 600ms. Most of all, the delay calculator is a tool, and you should use your ears.
Reverb Time Calculator
I primarily use this tool for reverb to get a tighter rhythmic affect. Generally, I use shorter time on percussive sounds (I tend to like punchier drums) and longer times on other instruments (with the exception of lowers frequencies.) It's often a good idea to roll off lower frequencies, but always use your ears in context with the mix.
Reverberation and delay/echo are actually the same thing. It just depends on the space and time that it happens within. Reverberation time is the amount of time required for the sound to "fade away" after the source of the sound has stopped. Keep that in mind when designing your reverb. Imagine the space for your sound if it helps. According to Wikipedia, "Reverberation, in psychoacoustics and acoustics, is a persistence of sound after the sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached."
Basically, I just like to use this to find times that will sync up with the tempo of my song.
