Abstract :
With the development of 3D audio, distance rendering in multi-channel spatial audio is becoming a focused issue. In this paper, a sound field reproduction method with distance information based on Ambisonics is proposed. By utilizing Image Method (IM) in Ambisonics, propagating function with distance information, which is expressed via acoustic intensity and Direct-to-Reverberant energy Ratio (DRR), is obtained. Combined it with variable separation, the loudspeaker driving signal with distance information can be derived eventually. The experimental results show that the proposed method validly reconstructed the target sound field and achieved the purpose of distance rendering.
