在Android上检测或估计蓝牙延迟(音频播放) [英] Detect or Approximate Bluetooth Latency on Android (Audio Playback)

问题描述

我目前正在使用连接的智能家居设备(例如Philips色相)在Android音频可视化器上工作，以可视化音乐.我无法补偿蓝牙扬声器引起的延迟.

I am currently working on an Android audio visualizer using connected smart home devices (such as Philips hue) to visualize music. I have trouble compensating the delay caused by bluetooth speakers.

我注意到，与许多其他视频流应用程序不同，Youtube应用程序在使用蓝牙扬声器时在音频和视频之间几乎没有延迟. 我认为，它们必须通过调整(延迟)视频信号来补偿蓝牙延迟.

I have noticed, that the Youtube app, in difference to many other video streaming apps, has almost no delay between audio and video, when using bluetooth speakers. I figure, that they must compensate for the bluetooth latency by adjusting (delaying) the video signal.

是否存在一种合理的方法来检测或近似蓝牙扬声器的延迟/延迟?

非常感谢您的帮助！

最好， 斯蒂芬

推荐答案

这不适用于蓝牙扬声器.但是，我已经能够使用Google的博士来测量蓝牙加密狗的音频延迟.使用 Glenn Kasten测试应用程序.

This would not work for Bluetooth speakers. However, I have been able to measure the audio latency of a Bluetooth dongle using Google's Dr. Rick O'Rang loopback dongle, using Glenn Kasten test app.
