You can see that sound travels exceptionally slowly in the air from this. Time: How about the speed of sound in solids? For an example lets say the stage is 16' deep, and the amps and drum set are side by side 12' from the front of the stage. If this is the case, you can use the same room reverb on all instruments to create the feeling that all instruments are playing in the same place. Calculate the time (in ms) or distance (in feet or meters) of flight from the front sub & LCR locations to the listening position as well as that from the rear sub to the listening position. Installation / Delay Calculations for 100ms @20Mhz with Prescalar as 8: RegValue = 65536-(Delay * Fosc)/(Prescalar*4)) = 65536-((100ms * 20Mhz)/(8*4)) = 3036 = 0x0BDC. While your Bluetooth signal broadcasts, it can only maintain its coherence and quality for a certain distance. But we're not quite done. S stands for the speed of the sound in feet per second at standard temperature and sea level. The slow speed of sound is responsible for the high frequency of echoes. the speed of sound is roughly 1100 ft/second (depends on temperature and elevation) . I'm not big into time aligning things. Ds is the delay in milliseconds. X is the distance from the main speakers in feet. Mono and stereo units are common but are often overlooked because they can be a bit fiddly At 0 C, the rate is around 331 meters per second. Can't hurt to see what happens. There are a few ways you can reduce Bluetooth latency. alignment units can be set up by punching in the distance between the delay speakers and Power. Awesome, thanks for posting.
