. NET audio conversion. AMR turn. mp3 (FFmpeg conversion method)

Recently, it seems to be working with the voice!

The second method of audio conversion, this method is more simple than the first way!

First, you need to download a "Ffmpeg.exe" plugin and put it in your project, such as:

The file is called in the program to help convert the audio format!

On the code:

usingSystem;usingSystem.Threading;usingSystem.IO;usingSystem.Diagnostics;usingsystem.security; Public Partial classcowala_201512chritmas_amrtest:system.web.ui.page{protected voidPage_Load (Objectsender, EventArgs e) {if(!IsPostBack) {changedplay.visible=false; }    }    protected voidFfmpeg_click (Objectsender, EventArgs e) {        if(amrfileup.hasfile) {stringKey =Amrfileup.filename; stringSavepath = Server.MapPath ("~/upload/amr/") +key;            Amrfileup.saveas (Savepath); stringMp3savepth = Server.MapPath ("~/upload/mp3/") + key. Split ('.')[0]. ToString () +". mp3"; if(!string. IsNullOrEmpty (CONVERTTOMP3 (Savepath, mp3savepth))) {changedplay.visible=true; CHANGEDPLAY.ATTRIBUTES.ADD ("src","upload/mp3/"+ key. Split ('.')[0]. ToString () +". mp3"); Response.Write ("<script>alert (' conversion succeeded! ');</script>"); }        }    }     Public stringCONVERTTOMP3 (stringPathbefore,stringpathlater) {        stringc = Server.MapPath ("/ffmpeg/") +@"ffmpeg.exe-i"+ Pathbefore +" "+Pathlater; stringstr =Runcmd (c); returnstr; }    /// <summary>    ///Execute cmd command/// </summary>    Private stringRuncmd (stringc) {Try{ProcessStartInfo Info=NewProcessStartInfo ("Cmd.exe"); Info. Redirectstandardoutput=false; Info. UseShellExecute=false; Process P=Process.Start (info); P.startinfo.useshellexecute=false; P.startinfo.redirectstandardinput=true; P.startinfo.redirectstandardoutput=true; P.startinfo.redirectstandarderror=true;            P.start ();            P.standardinput.writeline (c); P.standardinput.autoflush=true; Thread.Sleep ( +); P.standardinput.writeline ("Exit");            p.WaitForExit (); stringOUTSTR =P.standardoutput.readtoend ();            P.close (); returnoutstr; }        Catch(Exception ex) {return "Error"+Ex.        Message; }    }}

Then come to Zhang:

OK, so simple, don't dare not to believe your eyes, is actually so simple!

Finally, a question: After you finish the hand, wipe, used to use the left or right hand?
