Under such condition, we will introduce a versatile real time delay processor for digital audio signal (RTDP) and its application which has been made by myself in this paper.

Time Delay Spectrometry (TDS) is a new measuring technique which can be used to measure the complex frequency response and the complex time domain response of the audio system.

This avoids the disadvantage for real-time when audio-data is transmitted based on TCP, minishes the delay of network, improves the quality of audio-data transmission.
