Which, BTW, still sounds like crap. It is preferable to use an SPL meter (C-weighing, Slow Response) for greater accuracy. To calculate the speaker delay, divide the distance from the sound source by the speed of sound. If your snare hits on the 3rd beat, you can try out the whole notes delay time as a total reverb time. All direct, indirect, special, incidental, consequential or punitive damages arising from any use of this application or data contained herein are disclaimed and excluded. 2. Especially if you only have instruments that would normally play in the same room. Set the Presaclar bits in T1CON as per the delay calculations. You play the files back and point the device at the screen and it measures the offset between the audio and the video delay in either quarter frames or milliseconds. . Multiply the distance times 1.1 milliseconds. I'll have to see where my delays are currently at compared to the calcs. If you check echo lengths with the chart below, Dividing this number by your BPM will, thus, give you the value of a quarter note in milliseconds. Loudspeaker time delay DATA SHEET Speed of Sound - Introduction You may be surprised to learn just how slowly sound travels in air. To calculate speaker delay, simply divide the distance from the source of the sound to the listener by the speed of sound. You can open multiple calculators at the same time in resizable windows on the desktop and switch between Standard, Scientific, Programmer, Date calculation, and Converter modes. DISCLAIMER: Strings, for example, can sound amazing with a long reverb tail while the kick drum maybe should stay up front (it all depends on what you want to create). If you know another musicianthat the calculator could help, feel free to share it with him. Manually Calculating Delay. Stay Within Range and Avoid Obstacles. Please remember that these levels will need to be tweaked depending on the source recording and/or surround scheme. Get the Audioholics AV Gear Guide Ebook FREE! However, adjusting the delay too short may result in a flat 2-dimensional sound field between the front and rear speakers. Mono and stereo units are common but are often overlooked because they can be a bit fiddly Steve's explaination parallels mine exactly. But a 45 minutes to an hour later sound was out of sync. Pt10.0.1 syncheck. contact support@powersoundaudio.com or call 330-349-0943. 2. Weve said that timing is everything when it comes to sound transmission.
