    一種決定語音音高標記的方法，系藉以找出一語音之一組音高標記，此決定語音音高標記的方法系利用一可適性濾波器取得一基頻點與一基頻帶通訊號；求取基頻帶通訊號之復數個過零點位置；然後經由復數個過零點位置產生至少一組音高標記。
  3. The characteristic and key technologies of the system are as follows : ( 1 ) in realizing the live broadcast of audio and video, the problem of immense multimedia data and low networks bandwidth utilization ratio is solved by using mpeg - 4 as format of audio and video data. audio and video data are collected by video card cv500 which developed by beijing sum tone company ; meanwhile, the contradictory between the delay of networks transmitting and the quality of the image is well solved by setting a " bi - buffer area "

    系統實現中解決的關鍵問題和特色主要有以下幾個方面： （ 1 ）在視音頻直播功能的實現中，通過使用北京算通公司的cv500視頻採集卡和cv500sdk進行視音頻數據採集，並採用當今最新的圖像和語音編碼壓縮標準mpeg - 4作為視音頻數據的採集格式，既保證了圖像的質量，又大大縮減了視音頻所佔的帶寬，從而解決了多媒體數據量大、網路帶寬利用率低的問題；同時，通過設置環形緩沖區的辦法來調和網路傳輸延時與圖像質量之間的矛盾，取得了較好的效果。
  4. At last the audio - visual filter can get and regroup the pcm audio data which transformed into the time - frequency signals by the fft. at the same time the power spectrum can be displaying on the windows by using the win32 api functions. finally the test of this system shows the processes about transport stream of receiving in the collecting card, pushing in the bridge, separating in the parser, displaying in the audio - visual filter are satisfied with the data rata at the server

    音視頻效果filter內部通過獲取解碼后的pcm格式數據，並利用緩沖管理器對這些數據進行重新分組，然後對分組后的數據進行fft變換將時域信號變換到頻域之中，同時對變換后的數據作數學處理后得到其功率值，最後利用api畫圖函數對這些功率值進行了實時的特殊效果顯示。
