- Description
The CreateStream method will create a new .wav file using the format of the WAVEFORMATEX structure supplied.
If the file already exists, it is replaced.
If the file does not exist, it will be created if possible.
If the file cannot be created, the file remnants will remain.
If the method call is successful, the method returns true, and the TDx_SoundCaptureBuffer::StreamIsOpen property is true.
When open for streaming, raw sound data to the stream using the TDx_SoundCaptureBuffer::WriteToStream() method.
When finished streaming, you can close the stream using the TDx_SoundCaptureBuffer::CloseStream() method.
If the method call fails, the method returns false, and the OnError event will be triggered with one of the following values:
TDX_BADPARAMS
TDX_ERROR
- Parameters
FileName
The FileName parameter defines the path and filename of the .wav file to be created.
Format
The Format method parameter describes the format of the sound file to be created. This parameter must point to a user-supplied WAVEFORMATEX structure that has been filled with appropriate values.
You can retrieve the WAVEFORMATEX of the current buffer using the TDx_SoundCaptureBuffer::GetFormat() method.
You can also pass in a non-WAVE_FORMAT_PCM structure typecast as a WAVEFORMATEX, and supply the byte-size of the non-WAVE_FORMAT_PCM using the FormatSize parameter.
FormatSize
The FormatSize parameter must contain the size of the WAVEFORMATEX structure passed into this method via the Format parameter. Generally this will be sizeof(WAVEFORMATEX) but it may differ depending on the definition of the WAVEFORMATEX..
