In my app, I need to take input voice(surrounding noise)from the headset and at the same time need to play some tone as output sound in the headset.

However, during the search, I found that it is not possible to input the noise and send the output as sound/music. But with voice calls, When using Bluetooth SCO the input (microphone) and output (speaker) audio are managed separately by the system. During a phone call, Android's telephony stack handles this functionality, enabling both the microphone input and speaker output through the Bluetooth SCO connection.

I have used below to use the headset mic.

audiomanager.setBluetoothScoOn(true);

is there any way to take input from the headset and send output some music) at the same time?

  • Please provide enough code so others can better understand or reproduce the problem. – Community Aug 01 '23 at 15:31
  • You've given us some statements. But, you didn't actually ask something. Please edit the question, and explicitly tell us what you want to do. – Old Dog Programmer Aug 01 '23 at 17:39
  • What kind of headset exactly? And what type of audio are you trying to play? IIRC, SCO is limited to 8 or 16 kHz. – Michael Aug 03 '23 at 10:58
  • Yes, I'll play sound tones from 125 Hz to 12.5kHz (some targeted tones in this range). It is BLE and BRD type headphone, and for android we are using BRD. – Mayank Kansal Aug 03 '23 at 14:49
