Dynamic volume adjustment based on a player's forward vector relative to an audio source in a virtual world

A non-transitory computer readable medium comprising instructions stored thereon, the instructions are effective to cause at least one processor to:

• determine, for a local player, a reference direction comprising a forward vector;
• for an audio source, determine a relationship between the forward vector and a vector from the local player to the audio source;
• compute a scaling factor from the relationship;
• and
• apply the scaling factor to a sound amplitude of a signal associated with the audio source so that the sound amplitude varies as a function of the relationship.

A system comprising:

• a memory storing instructions;
• and
• at least one processor configured to execute the instructions effective to cause the system to:
• determine, for a local player, a reference direction comprising a forward vector;
• for an audio source, determine a relationship between the forward vector and a vector from the local player to the audio source;
• compute a scaling factor from the relationship;
• and
• apply the scaling factor to a sound amplitude of a signal associated with the audio source so that the sound amplitude varies as a function of the relationship.
