A method including receiving first audio data, receiving second audio data, compressing the first audio data as first compressed audio data, compressing the second audio data as second compressed audio data, generating a codec dependent container including a parameter associated with compressing the first audio data, compressing the second audio data, a reference to the first compressed audio data, and a reference to the second compressed audio data, generating a codec agnostic container including at least one parameter representing time-varying data associated with playback of the first audio data and the second audio data, and generating an audio package including the codec dependent container and the codec agnostic container.
