An individual who has actual knowledge of a patent which the individual believes contains Essential Claim s must disclose the information in accordance with section 6 of the W3C Patent Policy.
Audio on the web has been fairly primitive up to this point and until very recently has had to be delivered through plugins such as Flash and QuickTime. The introduction of the audio element in HTML5 is very important, allowing for basic streaming audio playback. But, it is not powerful enough to handle more complex audio applications.
For sophisticated web-based games or interactive applications, another solution is required. It is a goal of this specification to include the capabilities found in modern game audio engines as well as some of the mixing, processing, and filtering tasks that are found in modern desktop audio production applications.
The APIs have been designed with a wide variety of use cases [webaudio-usecases] in mind. That said, modern desktop audio software can have very advanced capabilities, some of which would be difficult or impossible to build with this system. Nevertheless, the proposed system will be quite capable of supporting a large range of reasonably complex games and interactive applications, including musical ones.
And it can be a very good complement to the more advanced graphics features offered by WebGL. The API has been designed so that more advanced capabilities can be added at a later time.
Sample-accurate scheduled sound playback with low latency for musical applications requiring a very high degree of rhythmic precision such as drum machines and sequencers.
This also includes the possibility of dynamic creation of effects. Processing of audio sources from an audio or video media element. Processing live audio input using a MediaStream from getUserMedia. Sending a generated or processed audio stream to a remote peer using a MediaStreamAudioDestinationNode and [webrtc]. Audio stream synthesis and processing directly using scripts. Spatialized audio supporting a wide range of 3D games and immersive environments:.
A convolution engine for a wide range of linear effects, especially very high-quality room effects. Here are some examples of possible effects:. Modular routing allows arbitrary connections between different AudioNode objects. A source node has no inputs and a single output. A destination node has one input and no outputs. Other nodes such as filters can be placed between the source and destination nodes.
For example, if a mono audio stream is connected to a stereo input it should just mix to left and right channels appropriately. In the simplest case, a single source can be routed directly to the output.
Modular routing also permits the output of AudioNode s to be routed to an AudioParam parameter that controls the behavior of a different AudioNode. In this scenario, the output of a node can act as a modulation signal rather than an input signal. An AudioContext interface, which contains an audio signal graph representing connections between AudioNode s.
An AudioNode interface, which represents audio sources, audio outputs, and intermediate processing modules. AudioNode s can be dynamically connected together in a modular fashion. AudioNode s exist in the context of an AudioContext. An AnalyserNode interface, an AudioNode for use with music visualizers, or other visualization applications.
An AudioBuffer interface, for working with memory-resident audio assets. These can represent one-shot sounds, or longer audio clips. An AudioDestinationNode interface, an AudioNode subclass representing the final destination for all rendered audio. An AudioParam interface, for controlling an individual aspect of an AudioNode 's functioning, such as volume.
An AudioListener interface, which works with a PannerNode for spatialization. An AudioWorklet interface representing a factory for creating custom nodes that can process audio directly using scripts. An AudioWorkletProcessor interface, representing a single node instance inside an audio worker.
A ChannelMergerNode interface, an AudioNode for combining channels from multiple audio streams into a single audio stream. A ChannelSplitterNode interface, an AudioNode for accessing the individual channels of an audio stream in the routing graph. A ConstantSourceNode interface, an AudioNode for generating a nominally constant output value with an AudioParam to allow automation of the value.
A ConvolverNode interface, an AudioNode for applying a real-time linear effect such as the sound of a concert hall. A DelayNode interface, an AudioNode which applies a dynamically adjustable variable delay. A GainNode interface, an AudioNode for explicit gain control.
A PeriodicWave interface for specifying custom periodic waveforms for use by the OscillatorNode. An OscillatorNode interface, an AudioNode for generating a periodic waveform.
A StereoPannerNode interface, an AudioNode for equal-power positioning of audio input in a stereo stream. A WaveShaperNode interface, an AudioNode which applies a non-linear waveshaping effect for distortion and other more subtle warming effects.
There are also several features that have been deprecated from the Web Audio API but not yet removed, pending implementation experience of their replacements:. A ScriptProcessorNode interface, an AudioNode for generating or processing audio directly using scripts. This interface represents a set of AudioNode objects and their connections. It allows for arbitrary routing of signals to an AudioDestinationNode. Nodes are created from the context and are then connected together.
BaseAudioContext is not instantiated directly, but is instead extended by the concrete interfaces AudioContext for real-time rendering and OfflineAudioContext for offline rendering. BaseAudioContext are created with an internal slot [[pending promises]] that is an initially empty ordered list of promises. Each BaseAudioContext has a unique media element event task source.
Additionally, a BaseAudioContext has two private slots [[rendering thread state]] and [[control thread state]] that take values from AudioContextState , and that are both initialy set to "suspended".
In the time coordinate system of currentTime , the value of zero corresponds to the first sample-frame in the first block processed by the graph. Elapsed time in this system corresponds to elapsed time in the audio stream generated by the BaseAudioContext , which may not be synchronized with other clocks in the system.
For an OfflineAudioContext , since the stream is not being actively played by any device, there is not even an approximation to real time. When the BaseAudioContext is in the " running " state, the value of this attribute is monotonically increasing and is updated by the rendering thread in uniform increments, corresponding to one render quantum. Thus, for a running context, currentTime increases steadily as the system processes audio blocks, and always represents the time of the start of the next audio block to be processed.
It is also the earliest possible time when any change scheduled in the current state might take effect. An AudioDestinationNode with a single input representing the final destination for all audio. Usually this will represent the actual audio hardware. All AudioNode s actively rendering audio will directly or indirectly connect to destination. An AudioListener which is used for 3D spatialization.
A property used to set the EventHandler for an event that is dispatched to BaseAudioContext when the state of the AudioContext has changed i. A newly-created AudioContext will always begin in the suspended state, and a state change event will be fired whenever the state changes to a different state.
This event is fired before the oncomplete event is fired. The sample rate in sample-frames per second at which the BaseAudioContext handles audio. It is assumed that all AudioNode s in the context run at this rate. In making this assumption, sample-rate converters or "varispeed" processors are not supported in real-time processing.
The Nyquist frequency is half this sample-rate value. Describes the current state of the BaseAudioContext. Getting this attribute returns the contents of the [[control thread state]] slot. Factory method for an AnalyserNode. Factory method for a BiquadFilterNode representing a second order filter which can be configured as one of several common filter types. Creates an AudioBuffer of the given size. The audio data in the buffer will be zero-initialized silent.
Factory method for a AudioBufferSourceNode. Factory method for a ChannelMergerNode representing a channel merger. Factory method for a ChannelSplitterNode representing a channel splitter.
using audio mixer unity
Two or more Android apps can play audio to the same output stream simultaneously, and the system mixes everything together. While this is technically impressive, it can be very aggravating to a user. To avoid every music app playing at the same time, Android introduces the idea of audio focus. Only one app can hold audio focus at a time.

Project Acoustics Unity Integration
This integration provides a few components that can be used without code directly in a scene for the most frequent usage scenarios:. In the Editor workflow, it is added to every scene, so that it can be properly previewed in the Editor. In the game, only one instance is created, in the first scene, and it is persisted throughout the game. There are a few customizable options in the initializer script. In order for positioning to work, the Ak Audio Listener script needs to be attached to the main camera in every scene. By default the listener is added automatically to the main camera.
Procedural Generated Sound Sources. The Audio Mixer is a multiplatform audio renderer that lives in its own module. It enables feature parity across all platforms, provides backward compatibility for most legacy audio engine features, and extends UE4 functionality into new domains. This document describes the structure of the Audio Mixer as a whole, and provides a point of reference for deeper discussions. Audio rendering is the process by which sound sources are decoded and mixed together, fed to an audio hardware endpoint called a digital-to-analog converter, or DAC , and ultimately played on one or more speakers. Audio renderers widely vary in their architecture and feature set, but for games, where interactivity and real-time performance characteristics are key, they must support real-time decoding, dynamic consuming and processing of sound parameters, real-time sample-rate conversion, and a wide variety of other audio rendering features, like per-source digital signal processing DSP effects, spatialization, submixing, and post-mix DSP effects such as reverb.
I was looking at a presentation yesterday about the new audio mixer in Unity3D 5, and there is an API for native plugins. There are many non-obvious but really important pieces to that puzzle:. The GUI which is developed in C. Note that the GUI is optional, so you always start out plugin development by creating the basic native DSP plugin, and let Unity show a default slider-based UI for the parameter descriptions that the native plugin exposes.
