Improve Android Audio Recording quality?

android, audio-recording

Solution

For recording and monitoring: You can use the sound recorder activity. Here's a snippet of code:

Intent recordIntent = new Intent(
                MediaStore.Audio.Media.RECORD_SOUND_ACTION);
            startActivityForResult(recordIntent, REQUEST_CODE_RECORD);

For a perfect working example of how to record audio which includes an input monitor, download the open source Ringdroid project: https://github.com/google/ringdroid

Look at the screenshots and you'll see the monitor.

For making the audio higher quality, you'd need a better mic. The built in mic can only capture so much (which is not that good). Again, look at the ringdroid project, glean some info from there. At that point you could implement some normalization and amplification routines to improve the sound.

Problem

Is there any way to record audio in high quality? And how can I read information that user is saying something? In Audio Recording application you can see such indicator (I don't know the right name for it).
