Hold the unit so that the microphone is pointed at the ceiling and position the microphone as closely to ear level as possible (at the sweet spot listening position) when running this test. A great way to create movement is by adding multiple delays, with different timings. However, if you still feel the stage is skewed so that the center is toward the right some distance. Use the right speaker delay formula. When it comes to sound, individuals can't perceive latency below 20ms and many struggle to discern a delay between 40 to 80ms either, although this varies from person to person. It is more easily for sound to bounce back from a flat surface than light. "Late Replies" (Blue Cat Audio): A delay plugin that allows you to create complex delay patterns with multiple delay lines. 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. of the adjustments are done in milliseconds. To calculate speaker delay, simply divide the distance from the source of the sound to the listener by the speed of sound. For example: Some recordings may boost the rear channels 1-3db higher than nominal due to poor mixing methods or deliberate wow factor. Loudspeaker time delay DATA SHEET Speed of Sound - Introduction You may be surprised to learn just how slowly sound travels in air. Technical Advances Update: Most receivers/processors built since 2003-2004 enable you to merely configure the distance from each speaker to the listening position. Next, we want to adjust the decay time to fill the gap between the pre-delay and the total reverb time. The standard method for improving system synchronisation and I recommend acquiring a multi-channel set-up disc such as the one from Avia, Sound & Vision, or DTS. According to Microsoft Low Latency delay is a routine in Windows 11/10, but it should not be noticeable. The goal is that the reverb of one snare hit dies just before the next snare hit.
