Binaural audio reproduction

An apparatus, comprising at least one processor and at least one non-transitory memory including computer program code, the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:

• receive at least one audio signal, the at least one audio signal corresponding to at least one audio source;
• receive location information associated with the at least one audio source, wherein the location information comprises at least distance information and at least one direction information for the at least one audio source;
• receive a head location information;
• generate, from the at least one audio signal, based at least partially upon the location information and the head location information, a left output signal and a right output signal, where the left output signal and the right output signal, when rendered, are configured to cause a perception of a location of the at least one audio source at least using inter-aural level differences based on the location information and the head location information, where the inter-aural level differences are derived from transfer function pairs.

A computer program, embodied on a non-transitory computer readable medium, the computer program configured to control a processor to perform a process, comprising:

• receiving at least one audio signal, the at least one audio signal corresponding to at least one audio source;
• receiving location information associated with the at least one audio source, wherein the location information comprises at least distance information and at least one direction information for the at least one audio source;
• receiving a head location information;
• generating, from the at least one audio signal, based at least partially upon the location information and the head location information, a left output signal and a right output signal, where the left output signal and the right output signal, when rendered, are configured to cause a perception of a location of the at least one audio source using inter-aural level differences based on the location information and the head location information, where the inter-aural level differences are derived from transfer function pairs.

A method comprising:

• receiving at least one audio signal, where the audio signal corresponds to an audio source;
• determining an audio object based upon the received at least one audio signal, where the audio object comprises audio object location information regarding a location of the audio source, where the audio object location information comprises at least one direction information and distance information;
• and
• generating, from the at least one audio signal, based at least partially upon the audio object location information, both a first left output signal and a first right output signal, where the first left output signal and the first right output signal, when rendered, are configured to cause a perception of the location of the audio source at least using inter-aural level differences based on the audio object location information, where the inter-aural level differences are derived from transfer function pairs.
