蓝牙是否足够快以在两个Android手机之间以原始字节数组的形式传输音频数据流？

Question

So the idea is to use AudioRecord to get a stream of audio from the microphone and send this stream over bluetooth to another device in the form of a raw byte array, just like I get it from AudioRecord, and at the same time over bluetooth receive the stream of audio from the other device and play it with AudioTrack . Is Bluetooth fast enough to do this between two phones while keeping a descent audio quality? If not, is there a way to do this?

Answer 1

It's fast enough for your wireless cell and music headphones. It's fast enough for audio and video streaming.

Answer 2

以电话麦克风记录的质量，应该没问题。

Answer 3

Required bandwidth is ~700 kbit/s for 44.1kHz/16bit MONO stream. Stereo stream doubles that (~1.4 kbit/s).
