matlab的應用

老師叫我們期末要做一個報告是有關matlab聲音方面的應用請問各位大大

能給我好建議嗎?(具體些的)例如將聲音從麥克風錄進去!!再經由matlab程式播放出來

或是利用電話撥號

從影幕上顯示他的頻率等等~~拜託各位了~~
這是之前我幫別人寫的試輸入電話號碼

產生相對應的撥號聲

並顯示出相對號碼你試試看吧%%%%%%%%%%%%%%%%%%%%%%%%%%%%%function callPhoneNumber(mobile)ringtone = [1209 697;...1336 697;...1477 697;...1209 770;...1336 770;...1477 770;...1209 852;...1336 852;...1477 852;...1336 941;...1209 941;...1477 941];[n

mobile(j)); sound(y{ind}
