This feature requires the audio scheduler to work in cooperation with the graphics layer and currently not in our radar. Both could be added to the package without touching any API surface. Recording and encoding audio is not in the roadmap initially. Tracklisting features to queue, unqueue multiple sources to a player playback features such as prefetching the next song.Composition and filtering (mixing of multiple signals, low-pass filter, reverb, etc).Multi channel synchronization and an internal clock.Multi channel playback (Playing multiple streams at the same time.).Prefetching before user invokes playback.Basic play functions such as play (looping and one-shot), stop, pause, gain control.

system codecs (OpenMax for Android and AudioUnit for iOS).

Initial decoder implementations, ideally delegating the decoding to the.

Playback from streaming network sources.

Playback of generated data (such as a PCM sine wave).

More information on the classification of the audio apps based on the features listed above is available at Appendix: Audio Apps Classification. Player also need shuffling and repeating features. Music players and radios require playlisting features, so the users can queue, unqueue tracks on the player.

Music software apps that require audio composition and filtering features.Mixers, multiple channels need to be multiplexed into a single device buffer.APIs that allow developers to schedule the playback, frame-level timers.Synchronization between channels/players.

HTTP Live Streaming works on both platforms but used to be inefficient on Android devices. Remote streamingĪudio players, radios and tools that streams audio need to be able to work with remote audio sources. Codec support in the parity of AudioUnit on iOS and OpenMAX on Android is good to have.

Most radio-like apps and music players need to play a variety of audio sources. DecodingĬodec library and decoding support. Most games require a background audio track and one-shot audio effects on the foreground. Games use a looping sample as the background music - looping functionality is also essential. Single or multi-channel playback with player controls such as play, pause, stop, etc. The abstractions we introduce today should be extendable to meet a majority of the features listed below in the long run. This section briefly explains the features required in order to support common audio requirements of the mobile applications. This is how we will enable users to expand their audio capabilities by partially delegating their work to lower-level layers of the audio package without having to rewrite their entire audio stack.

A good audio package shouldn't address the different class of requirements with isolated audio APIs, but must introduce common concepts and types that could be the backbone of both high- and low- level audio packages. Three major categories with majorly different requirements have revealed as a result of the survey. I (Burcu Dogan) surveyed the top iOS and Android apps for audio features. In order to address these concerns, I am proposing core abstractions and a minimal set of features based on the proposed abstractions to provide decoding and playback support.

support live streaming or other networking audio sources.

implement a memory-efficient playback model,.

provide high level abstractions to represents audio and audio processors,.

The current status of audio support under x/mobile is limited to OpenAL bindings and an experimental high-level audio player that is backed by OpenAL. In the scope of the Go mobile project, an audio package that supports decoding and playback is a top priority. This proposal suggests core abstractions to support audio decoding and playback on mobile devices. With input from David Crawshaw, Hyang-Ah Kim and Andrew Gerrand.
