| 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 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. |
