| Research Abstract |
This research addressed to develop an ultra-high speed audio finger print detection scheme to identify music from audio files such as mp3 which are exchanged through internet. We developed a new algorithm to synthesize audio fingerprint based on Haar-wavelet transform which is suitable for hardware implementation. Proposed scheme reached to 21. 86Gbps detection speed and this speed is almost 18 thousand times faster than conventional FFT based method.
