title: About Sound Cracking on Android
body: <p>We are developing an Android application that records input voice from a microphone and performs voice analysis on Android  and Chromebook.
  　However, when recording, perhaps because of the input level of the voice remains at MAX, the input level is too high and sound cracking occurs, resulting in audio data that is not suitable  for voice analysis.</p>
  <p>So, my question is, when recording input audio from the microphone with the above Android application, can you tell us an API that lowers the voice input level to prevent sound cracking? You can use any of the classes you use: MediaRecorder, AudioRecord, or any other available class.
  　We could not find anything, so we would like to consult with you.</p>
