The asset can help you with streaming from any connected system device (microphones, Line-In inputs, loopback interfaces, including ASIO on Windows..) and decoding audio files and streams from local file system and network

As new feature it supports multiple audio listeners in scene (based on Resonance spatialization, see below and online docs for details)

Please be aware that somehow advanced knowledge of Unity audio is required and is not aimed at novice users in general.

Please download demo builds from the following links to test all functionality first - they contain testing scenes for all included components; most of the scenes allow custom parameters such as filepath/urls to be set in order to test with your audio assets (on Windows ASIO support can be enabled, see online docs link below for details on how to configure the driver in order to work with the demo):

Demo builds for v 3.5

Windows x64 | macOS Universal* | Android** | Linux x64**

(* On macOS please allow running applications from unverified developers in System Preferences, and Allow the app to run, or alternatively codesign downloaded app on newer macOS(s): run

xattr -d com.apple.quarantine AudioStreamDemo.app

codesign --deep -s - -f AudioStreamDemo.app

chmod +x AudioStreamDemo.app/Contents/MacOS/AudioStreamDemo

in the folder where it was downloaded - Unity ad-hoc builds might require this)

(** not all features supported on Android and Linux in the demo

Support forum is here, but please read below first

current documentation is also available here

Please read included !!README1ST!! INITIAL IMPORT ERRORS.txt after importing the package for the first time which explains how to properly install and setup FMOD for Unity

AudioStream can stream and play from:

* internet radios M3U/8 and PLS playlists (+)

* audio files hosted on the internet/cloud such as podcasts

* local audio files on a regular filesystem (according to platform)

* non realtime and realtime streams from network / filesystem with caching for later usage, realtime streams can optionally play back while downloading

* memory locations containing encoded audio

* any connected input audio device (Microphone, Line-In inputs) including multichannel ones

* has broader HW support than Unity's Microphone class

* ASIO driver enabled devices on Windows

* non default devices on iOS, such as AirPods

* any input/microphone directly into spatialized Resonance AudioSource

Additionally it can

- save content streamed from network into local disk cache for offline playback

- stream/push any of the above into connected Icecast mountpoint

- stream between two LAN instances either Opus encoded audio up to two channels, or uncompressed AudioSource/AudioListener PCM audio

- play/redirect common Unity AudioSource to other than default system output, targeting specific channel/s/speakers

- play FMOD sounds directly on specified output and its channels/speakers using customized mix matrix

[FMOD sounds means audio files in all formats supported by FMOD, including multichannel ones above 8 channels which Unity currently can't import - either from local disk or from network URI, using FMOD networking only (i.e. no HTTPS)]

- redirect Unity MixerGroup to other than default system output with reasonable latency (++)

- has network proxy support via UnityWebRequest

Unity and other assets compatibility:

- compatible with all other audio packages when using AudioSource enabled, and networked components

- corresponding AudioSource can be used as usual including Unity spatialization, effecting and mixer routing - this means it can be used as AudioSource for e.g. Resonance/Oculus/Steam spatialization plugins, or any Unity Mixer in general (+++)

- fully IL2CPP compatible including standalones (Unity 2018.1 and up)

- has no PM dependencies on other optional Unity packages, not even builtin UGUI or TextMeshPro

- please be aware that the asset does not support WebGL

Included Documentation contains comprehensive install and usage guides such as building and recording on iOS, basic support for mobile background audio modes (++++), considerations regarding Unity latency modes and DSP buffer settings, setting up Icecast source and mountpoint and each relevant setting is fully documented in the Editor via e.g. member fields tooltips.

Runs almost on all platforms Unity currently has audio support for (+++++), at the time being tested on Windows, macOS and mobiles - iOS and Android.

There is a separate test/demo scene for each component/functionality and all source code is included.

Source is Unity API upgrader friendly (i.e. should not trigger any automatic source upgrades) and has no warnings once everything is set up.

* The whole package is as much unobtrusive as possible, there are no Editor customizations, except custom inspectors.

The asset is built upon FMOD Engine API and with all its source available it's also a good example on how to work with FMOD Engine and Unity in general

- please note that no FMOD Studio functionality is used, however.

Uses FMOD Studio by Firelight Technologies

NOTE: Agreement to FMOD EULA is required before downloading the FMOD Unity Intergration package directly from FMOD (they have very friendly indie policy though).

In general the asset should work with latest official FMOD release, either from the Asset Store, or from fmod.com (Unity Verified is recommended, though not necessarily required)

–––––––––––––––––––––––––––

Submitted with 2021.3.0 LTS Unity version

mainly for netstandard 2.1 support needed by OscCore

the rest of sources are not checked for compatibility with previous versions extensively, but initially 5.3.5 was recommended minimal version for mobiles, and earlier versions starting with 5.0 were OK for standalones.

see LICENSE for each asset used in the demo

–––––––––––––––––––––––––––

(+) Please note that M3U/8 support is currently limited to nonrecursive, nonchunked, direct streams only (in other words HLS is not supported). does not sprovide tags support for Icecast/SHOUTcast sources

(++) Unity AudioMixer native plugin is currently built for 64- and 32-bit Windows and macOS, sources are included

(+++) Unity Mixer works with all components, except AudioSourceOutputDevice (redirection to non default device and multichannel output separation)

(++++) User modifications of generated Xcode/Android Studio projects are required based on freely available information on the internet / e.g. RemoteCommandCenter is not included and must be implemented by user on iOS to get full player experience /, Android support is limited

(+++++) FMOD Studio Unity Integration officially has support for Android, macOS, iOS, tvOS, Metro, UWP, Windows and Linux (both x86 and x86_64) in publicly available version, with access to consoles version available upon request.

Please note that FMOD functionality required by this asset is not currently supported on WebGL due to - for now - missing threading support.
