Current interface:
interface AudioProcessingEvent : Event {
    readonly    attribute double      playbackTime;
    readonly    attribute AudioBuffer inputBuffer;
    readonly    attribute AudioBuffer outputBuffer;
    readonly    attribute object      parameters;
};

Interface with arrays of Float32Arrays:
interface AudioProcessingEvent : Event {
    readonly    attribute double      playbackTime;
    readonly    attribute Float32Array[] inputChannelBuffers;
    readonly    attribute Float32Array[] outputChannelBuffer;
    readonly    attribute object      parameters; 
};
