Как что? То что прочиталось в процедуре чтения здесь:

Код:

...
NumSamples := wChankSize div (SampleSize * Header.wChannels);
...

Вот процедура чтения:

Код:

procedure WriteWav(const FileName: String);
type
  TChunkID = packed array [0..3] of Char;
  THeader = packed record
    ChunkID       : TChunkID;
    ChunkSize     : Longword;
    Format        : TChunkID;
    Subchunk1ID   : TChunkID;
    Subchunk1Size : Longword;
    AudioFormat   : Word;
    NumChannels   : Word;
    SampleRate    : Longword;
    ByteRate      : Longword;
    BlockAlign    : Word;
    BitsPerSample : Word;
    Subchunk2ID   : TChunkID;
    Subchunk2Size : Longword;
    wChannels     : WORD;
  end;
var
  Header: THeader;
  NumSamples, BytsPerSample, Sample, I, J: Longword;
  fs: TFileStream;
  wChankSize    : Cardinal;

begin
  NumSamples := wChankSize div (SampleSize * Header.wChannels);
  BytsPerSample := 2;

  Header.ChunkID       := 'RIFF';
  Header.ChunkSize     := StrToInt(Form1.Memo2.Lines[1]);
  Header.Format        := 'WAVE';
  Header.Subchunk1ID   := 'fmt ';
  Header.Subchunk1Size := StrToInt(Form1.Memo2.Lines[4]);
  Header.AudioFormat   := $0001;
  Header.NumChannels   := StrToInt(Form1.Memo2.Lines[6]);
  Header.SampleRate    := StrToInt(Form1.Memo2.Lines[7]);
  Header.ByteRate      := StrToInt(Form1.Memo2.Lines[8]);
  Header.BlockAlign    := StrToInt(Form1.Memo2.Lines[9]);
  Header.BitsPerSample := StrToInt(Form1.Memo2.Lines[10]);
  Header.Subchunk2ID   := 'data';
  Header.Subchunk2Size := StrToInt(Form1.Memo2.Lines[12]);
  fs := TFileStream.Create('New File.wav',fmCreate);
  try
    fs.WriteBuffer(Header, SizeOf(Header));
      for I := 1 to NumSamples do
    begin
      for J := 1 to Header.NumChannels do
      begin
        Sample := 1111;
        fs.WriteBuffer(Sample, BytsPerSample);
      end;
    end;
  finally
    fs.Free;
  end;
end;
procedure TForm1.Button4Click(Sender: TObject);
begin
  if SaveDialog2.Execute then
  begin
    WriteWav(SaveDialog2.FileName);
  end;
  end;
end.

Выдает ошибку "Division by zero". Что делать?
