The speed of sound in the gas depends only on two constants \gamma and RRR and on the temperature but not on the air pressure or density, as it is sometimes claimed. The term speaker delay refers to the time it takes sound to travel from a speaker to the intended listener or destination. Weve said that timing is everything when it comes to sound transmission. It has seriously issus with audio sync via XLR. It also has a stereo width . In other words, this is the figure you should use at standard temperature and atmospheric pressure. So, you need to understand the speed of sound and the key factors that influence it to get the correct answer. If the delay for the speaker 11' away is 0 ms, then you should add a delay of (1000*3/1127) = 2.66 ms to the speaker that is only 8' away. On a large stage, with a large flown system, there can be some benefit in reducing the AVERAGE delay difference but we are talking about stages with widths of 75+ feet and depths of 40+ feet. The repeating sound you often hear from multiple speaker public To calculate the speed of sound in water, just choose the temperature - Fahrenheit F or Celsius C. Using the formula t = r / c shows that the propagation of sound over a distance r in meters (m) is always connected to a time t in seconds (s). You can use a delay to make your tracks more interesting by adding movement, and also depth. We get it by subtracting latency measured with the connected Bluetooth receiver and round-trip latency. To further clean up your mix try a low- (600Hz) and a high cut (ca600Hz) on your reverb. The Pre-Delay & Reverb Calculator can bea helpful toolbut the delay times it returns might not always be the best choice. But sometimes you also want the delay to be noticeable. Craig Vecchione's Live Sound & Production. 1/2 delay time: 1000 ms -> decay time: 1000 ms - 31.25 ms = 968.75 ms The second table shows you the delay lengths of different note values, which are a good starting point for your pre-delay and decay time. Enter the distance from the speaker in feet and the speed of sound into the calculator to determine the speaker delay. If you have a speaker under a balcony, measure the distance from the main speaker to it. X stands for distance from the speaker source to the listener in feet. Many manufacturers now produce Many authors derived equations from experimental data, but the equations are complicated, and they always contain higher-order polynomials and plenty of coefficients. Hence, the distance between the sensor and the object is one-half the distance traveled by the sound wave. Restarted the streaming PC and OBS.
