FIELD: acoustics.
SUBSTANCE: invention relates to providing audio signals, which perform rendering and output audio signals having different formats optimal for audio signal reproducing systems. Device for providing audio includes an object rendering unit, which renders an object audio signal by using geometrical information related to the object audio signal, a channel rendering unit, which renders an audio signal having the first number of channels into an audio signal having the second number of channels, and a mixing unit, which mixes the rendered object audio signal with the audio signal having the second number of channels.
EFFECT: optimization of a sound image for the listening environment due to optimization of a channel audio signal for the said listening environment by means of a step-up or a step-down mixing channel audio signal and rendering an object audio signal in accordance with geometric information.
