Interfaces for Soundfield Encoding and Decoding

This set of interfaces can be implemented to add support for encoding to and decoding from a soundfield format. There are four classes that are required to implement a soundfield format:

ISoundfieldPacket: Container for a single audio callback's resulting data for the soundfield format. For example, for first order ambisonics, this would contain an interleaved buffer of floats. For a proprietary spatial audio format, this would contain a bitstream.

USoundfieldEncodingSettingsBase: These are game thread-local, inspectable settings to define how a soundfield is getting encoded. For example, this may contain the order of an ambisonics sound field.

ISoundfieldEncodingSettingsProxy: This should contain all data from USoundfieldEncodingSettingsBase that needs to be read by an encoder or transcoder stream to apply the settings from an implementation of USoundfieldEncodingSettingsBase.

ISoundfieldEncoderStream: Class that encodes interleaved audio from a set of arbitrary locations to an ISoundfieldPacket. ISoundfieldDecoderStream: Class that decodes audio from an ISoundfieldPacket to interleaved audio at a set of arbitrary locations. ISoundfieldTranscodeStream: Class that translates a soundfield stream from one type to another. ISoundfieldMixerStream: Class that sums together multiple incoming ISoundfieldPackets into one ISoundfieldPacket.

ISoundfieldFactory: Factory class that declares the name of your format and creates new encoder, decoders, transcoders and mixers as requested.
