Audio Delay Convertor: Convert delay times to distance and vice-versa. Elevation gets more complicated- Elevation affects the density and humidity and if you go high enough, the temperature- they can all be factored in but I think temperature is the primary factor. The best result is for HTC One M7 with the ViMicRowX Bluetooth receiver: 330 - 290 = 40 ms, however round-trip for this device is too high (290 ms). A compromise would be to choose an average delay of 13.5 mSec that will result in minimum aggregate error throughout the measurement domain, though technically not textbook correct for those with a Smaart hard-on. If your snare hits on the 3rd beat, you can try out the whole notes delay time as a total reverb time. In this example, I took the 1/64 notes delay time as my pre-delay. The correlation is fairly simple. For example, when you want to add movement. Now you just have to subtract the pre-delay from the total reverb time to get the decay time. Fix Sound delays, lags and audio latency in Windows 11/10 Using multiple reverbs to create depth in your track, Often a room reverb for a song is adjusted to the snare. This tends to increase efficiency, longevity, and overall sound quality for reasons I will dive into at a later date.

Some of the more clever time In this example, the person is standing 500 feet from the source speaker. Assuming the air temperature of 20 C, the speed of sound is: You can derive these results by applying the formula c_air = 331.3 (1 + T/273.15), where T = 20C. The reason for this is to make the reverb vibe with the pulse of the track. If you check echo lengths with the chart below, If the music is not sequenced, estimate the BPM by manually counting the quarter notes for one minute. I'm not big into time aligning things.
