You can select your favorite device from a wide variety of candidates, and you can customize it, which is the attraction and strength of Android.However, on the other hand, it is often pointed out that it is difficult to understand.In this corner, I will explain such "I do not know this of Android" in an easy -to -understand manner.This time, answer the question, "Can you find out which codec the Bluetooth earphone is connected?"
***
Yes, Bluetooth audio devices such as earphones/headphones and speakers are easy to use with Android terminals and paired.You can check it.
On Android devices, there are optional codecs such as AAC and APTX in addition to the "SBC", which is essential for Bluetooth audio standards (A2DP profiles).Which codec corresponds are left to the discretion of the terminal manufacturer, but in order to meet the needs of high -resolution playback (sampling rate 48kHz or more/bit depth 24bit or more), it is possible to play high -resolution equivalent with irreversible compression.The number of terminals corresponding to APTX HD (up to 48kHz/24bit) and LDAC (up to 96kHz/24bit) is increasing.
Since the sound quality changes depending on the codec used in the same audio device, it is said that "codec is compatible with" ○○○ "", but if you are worried that it may be connected with other codecs, check it out.You should try it.
In some devices, dialogs are displayed such as "Use ○○○ codec" when pairing or connecting is started, but many terminals do not display anything.In that case, you will have to check the function of the "Developer Options" in the "Settings" app.
Android 8.0 To enable developer mode on the terminal, tap the build number seven times in the terminal information.If "This is now a developer", the "Settings" → "System" screen will see a "Options for Developer".Let's check it out.That is the codec used in Bluetooth audio playback.
