  "message": "audio: android.audio data source support (trace_processor + UI)\n\nAdd support for the android.audio data source, which captures the device\noutput mix as a per-stream encoded elementary stream (AAC-LC access units\nplus a one-time codec_config) in top-level TracePacket.audio_frame /\naudio_frame_error packets (extension fields 1002/1003).\n\ntrace_processor: a new audio_frame_importer plugin parses AudioFrame into\n__intrinsic_audio_frames (ts, stream_id, stream_name, codec_string,\nframe_number, codec, pts_us, is_config, sample_rate, channels, peak), with\nthe raw au_data kept in a parallel side-vector exposed via the\n__intrinsic_audio_frame_au_data(id) SQL function. An encoded frame with no\npeak field reads as 0 (a zero amplitude is dropped on the wire), so silence\nis a flat zero rather than a NULL gap. A per-stream byte cap and\nAudioFrameError reasons are surfaced as stats.\n\nUI: the dev.perfetto.Audio plugin renders each stream as an amplitude\n(waveform) counter track from the per-frame peak, one track per stream under\nan Audio group (as VideoFrames does per display). Each track has its own\nplay/pause button on the shell (play/resume the whole stream) and draws its\nown playhead, so streams play independently; selecting a range plays just\nthat part; playback speed is adjustable (0.5x-2x). Playback reconstructs an\nADTS stream from the AAC access units and decodes it with\nAudioContext.decodeAudioData.\n\nChange-Id: I0000000000000000000000000000000000000000\n",
