99eb27b196 Bug 865256 - Part 3a: Add AudioBufferPeakValue utility. r=ehsan 
From 6c057c02970c79d620527d08bc3755491c99b1d3 Mon Sep 17 00:00:00 2001
This is an equivalent, C-only implementation of blink's
VectorMath::maxmgv or Apple's vDSP_maxmgv. It finds the
maximum absolute value of the elements in a float buffer.
Used by blink's PeriodicWave implementation for normalization.

82519eedaf Bug 815643 - Part 2: Refactor our Web Audio FFT code into the FFTBlock class; r=roc 
This is useful in order for us to be able to borrow code from Blink with
fewer changes, and also to explore faster platform dependent FFT
implementations in the future if needed.

cea007a9a4 Bug 865247 - Part 3: Add a ProduceAudioBlock overload to handle simultaneous processing of multiple input and output ports; r=roc 
The ObtainInputBlock API is also changed to create an input block for one input
block at a time.  An array of these input blocks is then sent to
ProduceAudioBlock for processing, which generates an array of AudioChunks as
output.

Backwards compatibilty with existing engines is achieved by keeping the
existing ProduceAudioBlock API for use with engines with only a maximum of one
input and output port.

e0262ff6ca Bug 866434 - Part 3: Mix in the value generated by AudioNode inputs to AudioParams when getting their values during audio processing; r=roc 2013-05-01 23:12:59 -04:00

670b091738 Bug 866434 - Part 2: Give each AudioParam that is connected to an AudioNode an AudioNodeStream; r=roc 
These MediaStreams are used as a way to down-mix the input AudioChunks, and
also as a way to get proper stream processing ordering.  The MediaStream for
the source AudioNode is an input to these streams, and these streams in turn
are inputs to the MediaStream that the AudioNode that owns the AudioParam owns.
This way, the Media Streams Graph processing code will order the streams so
that by the time that the MediaStream for a given node is processed, all of the
MediaStreams belonging to the AudioNode(s) feeding into the AudioParam have
been processed.

This has a tricky side-effect that those streams also being considered when
determining the input block for the AudioNodeStream belonging to the
AudioParam's owner AudioNode.  In order to fix that, we simply special case
those streams and make AudioNodeStream::ObtainInputBlock ignore them.
