hi all.....<BR /><BR /><BR />I have open the Matlab, then i type the command to the command window in matlab. The command are follow:<BR /> siz = wavread('audio48kHz.wav','size');<BR /> [y,Fs,bits] = wavread('audio48kHz.wav');<BR /><BR />Of course, the wav file i have attached must in the Matlab current directory....<BR /><BR />Then click the workspace tab.... the second picture shown as below:<BR /><BR />Fs 48000<BR />bits 16<BR />siz [430242 1]<BR />y [430242*1 double><BR /><BR /><BR />i have question here:<BR /><BR />1. why 430242 * 2 ?<BR /><BR />2. acording to sampling theorem, Fs >= 2 fn<BR /><BR /> which one is Fs and which one is fn..... the image was <BR /> shown in the image..<BR /><BR />3. How to relate with sampling theoem with size wav file?<BR /><BR /><BR /><BR /><BR />i have attach the wav file and the images......<BR /><BR />any pro can help?<BR /><BR />Message Edited by loong1234 on <SPAN class="date_text">03-05-2008</SPAN> <SPAN class="time_text">07:51 PM</SPAN><BR /><BR />Message Edited by loong1234 on <SPAN class="date_text">03-05-2008</SPAN> <SPAN class="time_text">11:38 PM</SPAN><BR /><BR />Message Edited by loong1234 on <SPAN class="date_text">03-05-2008</SPAN> <SPAN class="time_text">11:42 PM</SPAN><BR /><BR />Message Edited by loong1234 on <SPAN class="date_text">03-06-2008</SPAN> <SPAN class="time_text">12:17 AM</SPAN>Thu, 06 Mar 2008 08:17:59 GMThttps://forums.xilinx.com/t5/Video-and-Audio/what-is-the-relationship-between-file-size-and-sampling-theorem/m-p/6854#M10788loong12342008-03-06T08:17:59ZRe: what is the relationship between file size and sampling theorem?......

This question is better suited for The Mathworks since it is regarding their functions. I don't see any reference to the Xilinx blockset, IP, etc. Please contact the Mathworks for help with this.<BR /><DIV></DIV>Thu, 20 Mar 2008 23:04:19 GMThttps://forums.xilinx.com/t5/Video-and-Audio/what-is-the-relationship-between-file-size-and-sampling-theorem/m-p/7591#M10792jeffreyh2008-03-20T23:04:19Z
