Patent ID: 8351612

Claim:
An apparatus of generating an object based audio contents, the apparatus comprising: an object audio signal obtaining unit to obtain a plurality of object audio signals by recording a plurality of sound source signals; a recording space information obtaining unit to obtain recording space information with respect to a recording space of the plurality of sound source signals; a sound source location information obtaining unit to obtain sound location information of the plurality of sound source signals; an encoding unit to generate object based audio contents by encoding at least one of the recording space information, and the sound source location information, and the plurality of object audio signals; an impulse sound source signal emitting unit to emit an impulse sound source signal; and an impulse sound signal receiving unit to receive the impulse sound source signal and to calculate an impulse response based on the received impulse sound source signal, wherein the received impulse sound source signal includes a sound signal that directly arrives at the impulse sound signal receiving unit from the impulse sound source signal emitting unit and all sound signals that arrive at the impulse sound signal receiving unit by being reflected from surfaces of walls of the recording space and objects existing in the recording space after being emitted from the impulse sound source signal emitting unit; the impulse response includes a plurality of impulse signals; and the recording space information includes at least one of a incoming time difference between the plurality of impulse signals, a sound pressure level difference between the plurality of impulse signals, and a incoming azimuth difference between the plurality of impulse signals.
