A respective panning gain may be calculated for each of the two or more audio signals using a count of the total number of audio sources and a count of a total number of output channels. The respective panning gain may be calculated further responsive to audio source metadata associated with each of two or more audio sources. Each of the two or more audio signals may be gain adjusted responsive to the respective panning gain. Each of the two or more gain adjusted audio signals may be mixed to create two or more output channels wherein a reproduction of the output channels produces enhanced comprehensibility. ## Claims ### Claim 1 A method for enhancing comprehensibility through spatialization comprising: receiving two or more audio signals each associated with one of two or more audio sources;
