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: http://juzzam.org:9090/myAudioFile.3gpp http://juzzam.org:9090/myAudioFile.mpeg http://juzzam.org:9090/myAudioFile.amr As a comparison, here is a similar audio file captured with audacity on a PC: http://juzzam.org:9090/myAudioFile_onPC.mp3 Has anyone been able to record high quality audio with the emulator? If not, is it any better on 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 Here is the Activity source: http://juzzam.org:9090/RecordMicrophone.java.txt 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.
