<string name="systraceHelp">
To use this feature it is necessary to launch a shell script on the Android device using ADB
shell. This script is responsible for launching an asynchronous Systrace and writing its
buffer to file when signaled by the Loopback App.
\n\n
At the completion of the audio glitch/buffer test the Loopback App will signal the script to
exit so the script must be started before each test.
\n\n
The Loopback App places this script on the Android device when launched at
\n
/sdcard/Loopback/loopback_listener
\n\n
Trace Categories: The loopback_listener script takes as arguments the categories to be
tracked in the Systrace. By default the sched and audio categories are included. For a list
of available categories see\n
developer.android.com/tools/help/systrace.html
\n\n
Example invocation:\n
adb shell \"sh /sdcard/Loopback/loopback_listener load am\"
</string>
<string name="calibrateSoundLevelHelp">
This feature is highly experimental. It will try various volume levels until it picks one
that it thinks is optimal. It has only been tested with the loopback plug and may fail
completely in open air.
