I am creating a simple application that records input from the microphone and store it into array of bytes. So I have searched a lot about this and eventually ended up using Directx DirectSound. Here is the code I am using:
using Microsoft.DirectX;
using Microsoft.DirectX.DirectSound;
private Thread CaptureSoundThread = null;
public CaptureBuffer applicationBuffer = null;
private SecondaryBuffer soundBuffer = null;
private Device soundDevice = null;
private void Form1_Load(object sender, EventArgs e)
{
soundDevice = new Device();
soundDevice.SetCooperativeLevel(this, CooperativeLevel.Normal);
// Set up our wave format to 44,100Hz, with 16 bit resolution
WaveFormat wf = new WaveFormat();
wf.FormatTag = WaveFormatTag.Pcm;
wf.SamplesPerSecond = 44100;
wf.BitsPerSample = 16;
wf.Channels = 1;
wf.BlockAlign = (short)(wf.Channels * wf.BitsPerSample / 8);
wf.AverageBytesPerSecond = wf.SamplesPerSecond * wf.BlockAlign;
int samplesPerUpdate = 512;
// Create a buffer with 2 seconds of sample data
BufferDescription bufferDesc = new BufferDescription(wf);
bufferDesc.BufferBytes = samplesPerUpdate * wf.BlockAlign * 2;
bufferDesc.ControlPositionNotify = true;
bufferDesc.GlobalFocus = true;
soundBuffer = new SecondaryBuffer(bufferDesc, soundDevice);
}
private void button1_Click(object sender, EventArgs e)
{
CaptureSoundThread = new Thread(new ThreadStart(WaitThread));
CaptureSoundThread.Start();
}
private void WaitThread()
{
while (true)
{
byte[] CaptureData = null;
CaptureData = (byte[])applicationBuffer.Read(0,
typeof(byte), LockFlag.None);
soundBuffer.Write(0, CaptureData, LockFlag.None);
// Start it playing
soundBuffer.Play(0, BufferPlayFlags.Looping);
}
}
But when I try to run the application, I get this annoying error:
BadImageFormatException
Could not load file or assembly 'Microsoft.DirectX.DirectSound.dll' or one
of its dependencies. is not a valid Win32 application. (Exception from
HRESULT: 0x800700C1)
I actually had to download the Microsoft.DirectX.DirectSound.dll from the internet because I couldn't find them in the Visual Studio assemblies.
