在Android中将声音录制到字节流中

Question

I want create an app which records a sound into bytestream and it can be listened again. It will not save the recorded audio into a file, rather it will save it into a hardware memory. And a play option will be there by which the recorded file can be played. Recorded system will be like talking tom: record the audio and play it instantly

Can anyone provide me a sample code for this functions ?

Answer 1

Without saving the audio into a file, you can use the AudioRecord class which lets you read the recorded audio into a byte array.

An easier option to code and use would be the MediaRecorder , although it will come with a loss in performance as it does save the audio into a file every time.
