audio - C# NAudio makes Noise WAV file without errors after POST from another page -


i posting file in callback(base64data); server using. when file seems file sounds white noise. help.

protected void page_load(object sender, eventargs e) {     var struser = request.form["userid"];     int userid = convert.toint32(struser);     var reader = new rawsourcewavestream(httpcontext.current.request.inputstream, new waveformat(44100, 16, 1));     var timestamp = datetime.now.tostring("yyyymmddhhmmssfff");     var target = new waveformat(44100, 8, 1);     var lastfilename = timestamp + "_" + struser + ".wav";     var savestreamfile = @"c:\soundbox\" + lastfilename;     var str = new waveformatconversionstream(target, reader);     wavefilewriter.createwavefile(savestreamfile, str);     reader.close();     str.close();

now have this: (please let me know silly things jump out @ make wav sound slow motion) made wav plays slooooowly: 

    var savestreamfile = @"c:\soundbox\" + lastfilename;     var wavfilestr = convert.frombase64string(request["data"].replace("-", "+").replace("_", "/").replace("\n", string.empty).replace("\r", string.empty).replace("data:audio/wav;base64,", string.empty));     memorystream stm = new memorystream(wavfilestr, 0, wavfilestr.length);      var target = new waveformat(44100, 16, 1);     var reader = new rawsourcewavestream(stm, new waveformat(44100, 16, 1));     var str = new waveformatconversionstream(target, reader);     wavefilewriter.createwavefile(savestreamfile, str);     reader.close();     str.close();

the explanation file playing you've got wrong wave format. number of channels , sample rate being explanation.

so have new waveformat(44100, 16, 1), how know correct format? i'd suggest trying 2 channels - new waveformat(44100, 16, 2), - double playback speed.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
