The FOH speakers are to the sides of the stage which is 24' wide. For the time-alighment is a must guys, the math just doesn't support your argument and the difference is not a clear improvement at all. "D" stands for the delay in milliseconds. so 17 feet/1100 = 0..015 . Some audiophiles opt for mono and stereo units. I recommend acquiring a multi-channel set-up disc such as the one from Avia, Sound & Vision, or DTS. google speed of sound and you can get the correction factors for your temp and elevation. Also any time spent in an ISR isn't counted by the delay routine so it makes the delay time inaccurate by extending it. View the calculated delay & reverb times. Adjust the master volume of your Receiver/Preamp to a common listening level you are accustomed to (say 75dB). Requires iOS 5.0 or later. 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. 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. Beats/minute msecs/beat Beats-per-minute: 120 BPM Beats-per-second: 2 Hz Length of 1 beat: 0.5 second = 500 msec Length of 1 bar (4 beats): 2 second Fraction msecs Delay = 3 / 4 of a beat = Dotted 1/2 note Optimising The Latency Of Your PC Audio Interface - Sound On Sound Whatever that table goes with may be doing internal processing so that you give it the distance to all of your speakers and it figures out the appropriate delay, or something, no way for me to tell. But, 1 ms per foot is the general standard. Contact. distance = speed of light * time. If the music is not sequenced, estimate the BPM by manually counting the quarter notes for one minute. You dont have to calculate this. How to use __delay_ms()? | Microchip If you are using a sequencer, the BPM corresponds to the tempo of the sequence.
