As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread: http://groups.google.com/group/android-developers/browse_thread/thread/860b5f346c59f2ca/b94fa1131077321f?lnk=gst&q=microphone+emulator#b94fa1131077321f
It is working; however, the audio is extremely poor -- too staticy for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR: http://developer.android.com/reference/android/media/MediaRecorder.html According to wikipedia, AMR encoding is only 8hz. Is there a better option available.. perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options.. we defined the sdcard in the avd manager). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
