Abstract: Audio signals are obtained and filtered. First and second audio processing tools are selected, and priorities associated with the first and second audio processing tools are assigned. In response to a higher priority associated with the first audio processing tool, the audio signal is encoded using the first audio processing tool. A multi-channel audio format for decoding the encoded may be selected and the encoded audio signal is decoded to the selected multi-channel audio format. Further, metadata associated with audio objects may be obtained. A gain level for each audio object may be determined based on the metadata and the gain level may be adjusted using the second audio processing tool. Another multi-channel audio format may be selected, and the gain level adjusted audio signal may be encoded based on the other selected multi-channel audio format. The gain level adjusted audio signal is output to be rendered via playback devices.
