Time: For reasons of public safety, Performance Indicators are [1] 2 Count the number of seconds until you hear thunder. To calculate delay times (in milliseconds) for your digital delay, first enter the beats per minute, or BPM. Pick the temperature unit. This means that the 2.9 ms of latency you set for your 44.1 kHz recording has become 8.7 ms. Add in the latency for the analog-to-digital and digital-to-analog converters, as well as their buffers, and our 128-sample example setting easily exceeds the 10 ms threshold. So if you can play an electric guitar 12 feet from your amp, you can easily cope with a 12ms . The importance of setting tempo-based delay times Delay & reverb time in milliseconds is directly correlated with BPM. To make it easier, here is a small example of how you can calculate the pre-delay of your reverb. Music is all about time. S stands for the speed of the sound in feet per second at standard temperature and sea level. Setting the delay too long may result in an echoed, unnatural surround field, or cause imaging shifts in the soundfield. The result is in m/s, and then, if needed, you have to convert it to other speed units. Then you take those numbers and use them to delay the audio to match the video delay. In the next section, we focus on all that you need to have in mind to understand the speed of sound in your current location. 1/64 delay time:31.25 ms > pre-delay time: 31.25 ms, 1/2 delay time: 1000 ms > decay time: 1000 ms 31.25 ms = 968.75 ms. CAR AUDIO CALCULATORS | Apex Customs Luckily, Bluetooth devices aren't doomed to latency and lag. Adjust the master volume of your Receiver/Preamp to a common listening level you are accustomed to (say 75dB).

Delaying Audio in OBS (Open Broadcaster Software) - StreamShark The speed of sound is (roughly) one foot per millisecond. It is more easily for sound to bounce back from a flat surface than light. DISCLAIMER: 31.25 ms (pre-delay time) 1/2 delay time: 1000 ms (decay time = total reverb time - pre-delay time = 1000 ms - 31.25 ms = 968.75 ms) . Guitars: Electric guitarists generally play a few feet from their stacks, and since the speed of sound in air is roughly a thousand feet per second, each millisecond of delay is equivalent to listening to the sound from a point one foot further away. There are a few ways you can reduce Bluetooth latency. For example, the Vizio SB36512-F6 has an ARC latency of 56 ms. Having the correct delay will prevent noticable echo on your sound system.
