For streaming and access to audio devices only the low/Core level API of FMOD Studio is used directly where appropriate (please note that no authoring FMOD Studio functionality is used)

- each output driver can be configured separately, on Windows ASIO support can be enabled, with customizable buffer size

- for list of supported audio formats please see formats and platforms FMOD recognizes (see e.g. Wikipedia or FMOD Documentation, for example on iOS and Android m4a/AAC is supported).

It aims at zero GC allocation at runtime and is suitable for long running automatically recoverable streaming.

For network retrieval is used Unity provided UnityWebRequest - that means all sensible connection scenarios such as secure connections, redirects, custom headers and proxies,... supported by it are available now.

Note: being streaming oriented it does not provide typical offline audio processing such as advanced audio clip offline signal manipulation - these are reserved for Unity AudioClip where appropriate.

List of included components (note they are all in the demo builds):

AudioStream - can stream supported formats from networked or local filesystem sources and play it via Unity AudioSource; supports saving content into local disk cache

AudioStreamMinimal - same as above, but plays the audio saparately via FMOD, not going through Unity audio system.

AudioStreamRuntimeImport - can download at faster than realtime playback speeds, caches decoded PCM data which can be retrieved and played back later as an AudioClip without touching the network

AudioStreamMemory - decodes audio data stored at IntPtr memory location and plays them as an AudioClip, can use cache with user identifier to retrieve immediately later

IcecastSource - pushes playing Unity AudioSource content encoded as uncompressed PCM, OGGOPUS, or OGGVORBIS into opened Icecast mountpoint

AudioSourceOutputDevice - redirects playing Unity AudioSource to specified/non default system output

- can perform multichannel separation of output, demo scene shows how to play a MONO AudioClip on selected channel of multichannel output device

AudioStreamInput - streams any connected input device into an AudioSource including multichannel microphones

- can open and stream from [loopback] devices meaning you can e.g. capture currently being played overall audio on system output on standalone platforms (which have loopback or are setup to be available)

AudioStreamInput2D - same as above, except is optimized for latency and doesn't go through Unity spatialization

AudioStreamInput_iOS - can stream from all connected devices on iOS into an Unity AudioSource, including e.g. AirPods

ResonanceSource - positional streamed audio using FMOD's provided Google Resonance native plugin

ResonanceSoundfield - can play a- and b- format ambisonics files using FMOD's provided Google Resonance native plugin

ResonanceInput - provides spatialized microphone input - streams any audio input similar to AudioStreamInput components to 3D positioned AudioSource using FMOD's provided Google Resonance native plugin

AudioStreamListener - can be used as standalone audio listener for AudioStreamListenerSource(s), with its own system audio output and number of GameObjects with this components is not limited (technically there is only limit now because of constrained FMOD resources)

AudioStreamListenerSource - serves as source audio for AudioStreamListener, with all user adjustable Resonance 3D parameters, requires Unity AudioSource,

AudioStreamOscSource - OSC transport for AudioStreamNetworkSource

AudioStreamNetMQSource - NetMQ transport for AudioStreamNetworkSource

- these act as network source for client components providing OPUS encoded (max. 2-channels) or PCM stream over LAN

AudioStreamOscClient - OSC transport for AudioStreamNetworkClient

AudioStreamNetMQClient - NetMQ transport for AudioStreamNetworkClient

- LAN clients for the above sources which are played via normal Unity AudioClip either 2D or spatialized

GOAudioSaveToFile - saves audio of any AudioSource into a PCM16 WAV file

AudioSourceCaptureBuffer - small utility component for exposing audio filter buffer of a game object

MediaSourceOutputDevice - direct FMOD API playback not using Unity audio system - an audio file can be played on any available system output, and can play multichannel audio files - two demo scenes are included for this component

three simple playback channels separating components for AudioSource, AudioClip and AudioStreamInput:

AudioStreamInputChannelsSeparation - splits recording channels of audio being recorded from an AudioStreamInput* into separate single channel AudioSources prefabs and instantiates them in the scene

AudioSourceChannelsSeparation - splits audio of an AudioSource/AudioClip being played on current Unity output into separate single channel AudioSources prefabs and instantiates them in the scene

AudioClipChannelsSeparation - splits original channels of (a multichannel) AudioSource/AudioClip being played into separate single channel AudioSources prefabs and instantiates them in the scene

AudioStreamDevice native mixer plugin:

AudioStream OutputDevice effect - redirects AudioMixerGroup to specified/non default system output

AudioStream InputDevice effect* - records from a system audio input directly into AudioMixerGroup

* currently Windows only

- on Windows both above effects have ASIO alternatives
