-Audio Processing Per 10ms Analysis
+Following are the specific tests in Chrome that attempt to measure audio performance.
-Test Code: process_test.c
+====Audio Processing Per 10ms Analysis====
-Details:
+This test instruments WebRTC's AudioProcessing Module under various configurations to measure mic to render audio processing for a 10ms audio frames.
-. Uses WebRTC AudioProcessingModule to simulate mic to             render audio processing.
+APM can be configured on the following
-. AudioEngine Configuration touch points : Sample Rate, Input        and Output Channels, Reverse Channels, Echo Cancellation,        Gain Control, Noise Suppression, Voice Activity Detection,              Level Metrics, Delay, Drift Compensation,Echo Metrics
+ Sample Rate, Input and Output Channels, Reverse Channels, Echo Cancellation,   Gain Control, Noise Suppression, Voice Activity Detection,  Level Metrics, Delay, Drift compensation, Echo Metrics
 Logic:
     For every Input AudioFrame
