About this app

[What is earbuds delay?]

1. The time when sound playback starts on the device (smartphone, etc.)

2. The time when the sound actually comes out of the earbuds.

The time difference between 1. and 2. is the delay of the earbuds.

YouTube or video player apps show the video as late as the delay time of the audio in order to eliminate this delay. So users feel there is no delay.
However, since this app does not perform such manipulations, you can experience the delay of your earbuds devices.

In general, devices connected wirelessly, such as Bluetooth, have a longer delay than devices connected by wire.


[How to test the delay]

When the clock hand pass 0ms(milliseconds), the device starts playing 'tick' sound. The delay is where the clock hand is located when the earbuds actually make a 'tick' sound.


I hope this app is useful to you.
Thank you.

Ratings and reviews

It works superbly! Im not kidding, i used it for many Wireless headphone devices and they gave a different result each, a very good app idea. (If i could i would. Add better Ui, and better app design! Sure it may not be much, but this is a good way to actually measure a sound delay with devices without using a sound amplifier.)

Useful app for seeing the realtime lag for audio. I use to gauge how different settings and Bluetooth modes have different amounts of lag. tip for using the app: press play, and watch the dial. when you hear the sound, look at the dial pointer to see what the delay is. don't try to click pause to time the delay. FYI, my bt headphones have 200ms delay via LDAC, 300ms delay using SBC.

Easy, plain, simple: test the audio latency of a digital sound device. (Note to creator: you mention in the description that bluetooth devices tend to have more latency than other types. But analog speakers and headphones have NO latency at all, as dictated by laws of nature! Electricity in wires travels with near-light speed).
