Method and apparatus for control of randering multiobject or multichannel audio signal using spatial cue

A method for processing of audio signals comprising:

• identifying a level of input audio signals, N channels of input audio signals, and M channels of output audio, where N and M are integers;
• adjusting the level of input audio signal based on a gain for each N channels of the input audio signal;
• and
• rendering the N channels of input audio signals having the adjusted level into the M channels of output audio signal for an audio scene,
• wherein the gain is controlled using audio scene information for rendering,
• wherein the audio scene information is an interaction control signal inputted by a user, and includes output position or output level of the input audio signal.

A method for processing of audio signals comprising:

• extracting (i) a level of input audio signals, (ii) the number of channel for input audio signals, and (iii) the number of channel for output audio signals from a bitstream;
• determining gain for channel and band of the input audio signals;
• and
• rendering N channels of the input audio signals into the M channels of output audio signal for an audio scene by adjusting the gain for each N channels of the input audio signal;
• and
• generating the output audio signal based on a result of the rendering for the input audio signal,
• wherein the gain is controlled using audio scene information for rendering,
• wherein the audio scene information is an interaction control signal inputted by a user, and includes output position or output level of the input audio signal.
