Adjust the volume levels of each channel until they sound similar in volume. The results of the experiment determined that the average audio leading threshold for a/v sync detection was 185.19 ms, with a standard deviation of 42.32 ms The ATSC says At first glance it seems loose: +90 ms to -185 ms as a "Window of Acceptability" and Undetectable from -100 ms to +25 ms Detectable at -125 ms & +45 ms In real life it is extremely rare to use a long software delay in an embedded application as the processor cant do anything else for the duration of the delay and cant even end it early from an ISR. I'm not big into time aligning things. If you have a digital or analog watch, begin timing as soon as you see the lightning and stop as soon as you hear the thunder. A common delay would be 5 milliseconds. By plugging in our variables we can easily find the correct delay time to align our tower with our P.A. D = X / S * 1000 Where D is the delay (ms) X is the distance from the source (ft) S is the speed of sound (ft/s) This is equal to 1126 feet/second at sea level and standard temperature To calculate the speaker delay, divide the distance from the sound source by the speed of sound. Of course, with tiered stadium seating you have a third dimension to consider when calculating the average delay as distance does not vary as much for a flown system which tends to track the change in elevation more evenly naturally. D=44 milliseconds (ms) delay between the two speakers below. For example this correlation is important when calculating a delay line and using the Haas effect. Audio Delay Convertor: Convert delay times to distance and vice-versa. This helps to understand which parts of the website you find most interesting and useful. So, if you divide the distance from the speaker by the sound speed, you get the exact time it takes the sound to travel from the source to the right location. .

Sounds good. Thus, synching these two things is imperative to getting a strong mix. Remember that you can always change the units of speed of sound: mph, ft/s, m/s, km/h, even to knots if you wish to. So, your speaker delay calculator is an effective tool for troubleshooting the speaker delay. I have a DRZ 9255 and I was under the impression you only had to measure the distance you are from each speaker and convert it over to cm's Actually, I think this should be my question instead of a response to this thread. The reason for this is to make the reverb vibe with the pulse of the track. Time difference per sound path distance ms per meter or. Time: However, adjusting the delay too short may result in a flat 2-dimensional sound field between the front and rear speakers. Frankly, I have not heard enough of a difference over the average listening area (on a smaller stage) to justify the effort. The speed of sound is (roughly) one foot per millisecond.
