recording and recording sound playing by VS1003B

Post by dklee »

Dear all~

I try to make a heartbeat recording and playing at the same time by VS1003B.

But I don't know how can do this.

Is it possible by VS1003B?

Please guide me.

Thank you in advance.

Hi,
What do you mean by "playing at the same time"?

If you mean to monitor the encoded audio, then that's possible with the normal encoding mode of vs1003b.

If you mean to play a different audio stream, then that's not possible with vs1003b, you'll probably want vs1063a/vs1163a, which has a codec mode (simultaneous encoding and decoding of a few simple formats).

Even then your microcontroller needs to perform the saving of encoded data and sending of the audio to play.

Hi pasi~

Thank you for your reply.

I want to listen with earphones while receiving sound input through the microphone and make a sound file.
