Default audio source
Microphone audio source
Audio source for a submix of audio streams to be presented remotely.
An application can use this audio source to capture a mix of audio streams that should be transmitted to a remote receiver such as a Wifi display. While recording is active, these audio streams are redirected to the remote submix instead of being played on the device speaker or headset.
Certain streams are excluded from the remote submix, including
STREAM_RING
,
STREAM_ALARM
,
and
STREAM_NOTIFICATION
. These streams will continue
to be presented locally as usual.
Capturing the remote submix audio requires the
CAPTURE_AUDIO_OUTPUT
permission.
This permission is reserved for use by system components and is not available to
third-party applications.
Voice call uplink + downlink audio source
Microphone 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.
Voice call downlink (Rx) audio source
Microphone audio source tuned for voice recognition if available, behaves like
DEFAULT
otherwise.
Voice call uplink (Tx) audio source
