MediaRecorder.AudioSource

• public static final int DEFAULT  /  Constant Value: 0 (0x00000000)
• Default audio source
• public static final int MIC / Constant Value: 1 (0x00000001)
• Microphone audio source
• public static final int VOICE_UPLINK  / Constant Value: 2 (0x00000002)
• Voice call uplink (Tx) audio source
• public static final int VOICE_DOWNLINK / Constant Value: 3 (0x00000003)
• Voice call downlink (Rx) audio source
• public static final int VOICE_CALL  / Constant Value: 4 (0x00000004)
• Voice call uplink + downlink audio source
• public static final int CAMCORDER  / Constant Value: 5 (0x00000005)
• Microphone audio source with same orientation as camera if available, the main device microphone otherwise
• public static final int VOICE_RECOGNITION / Constant Value: 6 (0x00000006)
• Microphone audio source tuned for voice recognition if available, behaves like DEFAULT otherwise.
• public static final int VOICE_COMMUNICATION / Constant Value: 7 (0x00000007)
• icrophone audio source tuned for voice communications such as VoIP.
• It will for instance take advantage of echo cancellation or automatic gain control if available. It otherwise behaves like DEFAULT if no voice processing is applied.

• MPEG4 media file format
• public static final int AMR_NB / Constant Value: 3 (0x00000003)
• AMR NB file format
• public static final int RAW_AMR / Constant Value: 3 (0x00000003)
• Deprecated in favor of MediaRecorder.OutputFormat.AMR_NB
• AMR NB file format
• public static final int AMR_WB / Constant Value: 4 (0x00000004)
• AMR WB file format
• public static final int AAC_ADTS / Constant Value: 6 (0x00000006)
