Remarks

Loads a sound file stored inside a memory buffer for editing purposes. The sound file can be a stream file or a MOD music file (see the LoadSound method for supported formats).

You can manage how loaded sound will be added to the existing editing session through a previous call to the SetLoadingMode method.

You can limit the range of sound data that will be loaded from the given sound file with a previous call to the SetLoadingRange method.

For loading files in RAW format use the LoadSoundFromRawMemory method.

In case you should need loading a specific single channel of the audio file, use the LoadSoundChannelFromMemory method.

A successful call to this method will fire the SoundLoadingStarted event followed by a number of SoundLoadingPerc events and finally by the SoundLoadingDone event.

IMPORTANT TOPIC: remember that the memory buffer containing song data must not be moved by the garbage collector and needs to be available till the call to the CloseSound method.

Return value

Sample

Below you can find a couple of samples that demonstrate how to load a sound stored in memory in Visual Basic.NET and Visual C# : in these samples the file is taken from a file and its contents are stored in memory.

Visual Basic.NET

' declare the memory buffer (cannot be a local variable)

Dim m_byteBuffer() As Byte

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim openFileDialog1 As New OpenFileDialog

If openFileDialog1.ShowDialog() <> DialogResult.OK Then

    Return

End If

' put the song file into a stream

Dim streamFile As FileStream

streamFile = New FileStream(openFileDialog1.FileName, FileMode.Open)

Dim binReader As BinaryReader

binReader = New BinaryReader(streamFile)

' reallocate the memory buffer space and store the song

ReDim m_byteBuffer(streamFile.Length)

binReader.Read(m_byteBuffer, 0, streamFile.Length)

If audioSoundEditor1.LoadSoundFromMemory(m_byteBuffer, streamFile.Length) = AudioSoundEditor.enumErrorCodes.ERR_NOERROR Then

    ' do domething

    ....

End If

End Sub

Visual C#.NET

// declare the memory buffer (cannot be a local variable)

byte[] m_byteBuffer = null;

private void buttonLoad1_Click(object sender, System.EventArgs e)

{

OpenFileDialog openFileDialog1 = new OpenFileDialog();

if (openFileDialog1.ShowDialog() != DialogResult.OK)

    return;

// put the song file into a stream

FileStream      streamFile = new FileStream (openFileDialog1.FileName, FileMode.Open);

BinaryReader    binReader = new BinaryReader (streamFile);

//  allocate the memory buffer space and store the song

m_byteBuffer = new byte[streamFile.Length];

binReader.Read (m_byteBuffer, 0, (int) streamFile.Length);

// load song from memory buffer

if (audioSoundEditor1.LoadSoundFromMemory (m_byteBuffer, (Int32) streamFile.Length) == AudioSoundEditor.enumErrorCodes.ERR_NOERROR)

{

    // do something

    ...

}

}
