In this paper, we propose a noble audio streaming scheme for the perceptual audio coder over the packet-based network. At first, a single frame is split into several subframes which are independently decoded based on the packet size for the robust error concealment. Also, we further improve the subframe splitting techniques by allocating spectral lines adaptively. Through an informal listening test, it is discovered that our approach enhances the audio signal under the lossy packet network.
