	Name	Description	Size	Coverage
	AlignedTArray.h	E: element type, must be a POD type. N: N bytes alignment for the first element, defaults to 32 S: S bytes of inline storage	3805	100 %
	AlignmentUtils.h		762	-
	AnalyserNode.cpp	static	12223	92 %
	AnalyserNode.h		2807	100 %
	AudioBlock.cpp	Heap-allocated buffer of channels of 128-sample float arrays, with threadsafe refcounting. Typically you would allocate one of these, fill it in, and then treat it as immutable while it's shared. Downstream references are accounted specially so that the creator of the buffer can reuse and modify its contents next iteration if other references are all downstream temporary references held by AudioBlock. We guarantee 16 byte alignment of the channel data.	5587	94 %
	AudioBlock.h	An AudioChunk whose buffer contents need to be valid only for one processing block iteration, after which contents can be overwritten if the buffer has not been passed to longer term storage or to another thread, which may happen though AsAudioChunk() or AsMutableChunk(). Use on graph thread only.	4480	100 %
	AudioBuffer.cpp	AudioBuffers can be shared between AudioContexts, so we need a separate mechanism to track their memory usage. This thread-safe class keeps track of all the AudioBuffers, and gets called back by the memory reporting system when a memory report is needed, reporting how much memory is used by the buffers backing AudioBuffer objects.	17671	95 %
	AudioBuffer.h	An AudioBuffer keeps its data either in the mJSChannels objects, which are Float32Arrays, or in mSharedChannels if the mJSChannels objects' buffers are detached.	4766	100 %
	AudioBufferSourceNode.cpp	Media-thread playback engine for AudioBufferSourceNode. Nothing is played until a non-null buffer has been set (via AudioNodeTrack::SetBuffer) and a non-zero mBufferSampleRate has been set (via AudioNodeTrack::SetInt32Parameter)	31897	93 %

	AudioContext.cpp		49870	92 %
	AudioContext.h	This runnable allows the MTG to notify the main thread when audio is actually flowing	18225	100 %
	AudioDestinationNode.cpp		29110	90 %
	AudioDestinationNode.h		4715	100 %
	AudioEventTimeline.cpp		19271	99 %
	AudioEventTimeline.h	Converts an AudioTimelineEvent's floating point time members to tick values with respect to a destination AudioNodeTrack. This needs to be called for each AudioTimelineEvent that gets sent to an AudioNodeEngine, on the engine side where the AudioTimlineEvent is received. This means that such engines need to be aware of their destination tracks as well.	12187	96 %
	AudioListener.cpp		3767	94 %
	AudioListener.h		2254	100 %
	AudioNode.cpp		20170	93 %
	AudioNode.h	The DOM object representing a Web Audio AudioNode. Each AudioNode has a MediaTrack representing the actual real-time processing and output of this AudioNode. We track the incoming and outgoing connections to other AudioNodes. Outgoing connections have strong ownership. Also, AudioNodes that will produce sound on their output even when they have silent or no input ask the AudioContext to keep playing or tail-time references to keep them alive until the context is finished. Explicit disconnections will only remove references from output nodes after the graph is notified and the main thread receives a reply. Similarly, nodes with playing or tail-time references release these references only after receiving notification from their engine on the graph thread that playing has stopped. Engines notifying the main thread that they have finished do so strictly after producing and returning their last block. In this way, an engine that receives non-null input knows that the input comes from nodes that are still alive and will keep their output nodes alive for at least as long as it takes to process messages from the graph thread. i.e. the engine receiving non-null input knows that its node is still alive, and will still be alive when it receives a message from the engine.	11277	96 %
	AudioNodeEngine.cpp		13078	62 %
	AudioNodeEngine.h	This class holds onto a set of immutable channel buffers. The storage for the buffers must be malloced, but the buffer pointers and the malloc pointers can be different (e.g. if the buffers are contained inside some malloced object).	13452	65 %

	AudioNodeExternalInputTrack.cpp	static	8520	97 %
	AudioNodeExternalInputTrack.h	This is a MediaTrack implementation that acts for a Web Audio node but unlike other AudioNodeTracks, supports any kind of MediaTrack as an input --- handling any number of audio tracks and handling blocking of the input MediaTrack.	1653	100 %
	AudioNodeTrack.cpp	An AudioNodeTrack produces a single audio track with ID AUDIO_TRACK. This track has rate AudioContext::sIdealAudioRate for regular audio contexts, and the rate requested by the web content for offline audio contexts. Each chunk in the track is a single block of WEBAUDIO_BLOCK_SIZE samples. Note: This must be a different value than MEDIA_STREAM_DEST_TRACK_ID	20373	98 %
	AudioNodeTrack.h	An AudioNodeTrack produces one audio track with ID AUDIO_TRACK. The start time of the AudioTrack is aligned to the start time of the AudioContext's destination node track, plus some multiple of BLOCK_SIZE samples. An AudioNodeTrack has an AudioNodeEngine plugged into it that does the actual audio processing. AudioNodeTrack contains the glue code that integrates audio processing with the MediaTrackGraph.	8925	88 %
