waveOutClose(): Closes the specified instance of the audio device. Unfortunately with my decision to drop SDL I lost my way of handling audio. This instance is cached and later used to notify the system of audio messages.

See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer Network Developer Network Developer Sign in MSDN subscriptions This method opens the audio device and allocates, prepares, and adds buffers to the recording queue.

Copy public WaveFile() { m_whdr = new Wave.WAVEHDR[2]; } The Play method is responsible for starting playback of an audio file. Createfile The event is signaled whenever the state of the waveform buffer changes. waveOutWrite(): Starts playing the queued buffer. https://msdn.microsoft.com/en-us/library/windows/desktop/dd743866(v=vs.85).aspx You can do either.

Mar 11, 2010 at 3:50pm UTC Disch (13766) DirectSound or waveOut DirectSound will get you lower latency. You signed out in another tab or window. WORTH ITI'm just saying for people being TRUE BLUE GAMEBOY MASTERS it might be a little variable? I mean you have this WAVEFORMATEX wiInfo;, but I don't see where you're actually filling it / reading it from the file.


I forgot how I got it, though... https://support.microsoft.com/en-us/kb/316609 waveInUnprepareHeader(): Releases a previously prepared WAVEHDR and data block. Windows Error Codes To minimize memory use, the sample utilizes multiple buffers, as it is possible to queue them for playback and recording. This API provides complete control of the audio system and buffering to the developer.

What does "M.C." in "M.C. check my blog When the event is signaled, you can get the current state of the waveform buffer by checking the dwFlags member of the WAVEHDR structure. (See waveOutPrepareHeader.) If fdwOpen contains the CALLBACK_NULL The method writes all of the appropriate header information and then iterates through each buffer and writes the recorded data. sizeof(WAVEFORMATEX) might not be the size of the "info" chunk in the header, so you might be reading too much / too little data.

WAVE_MAPPER can be used in place of a device identifier when opening an audio device in order to automatically find a best fit. That's pretty much your best option of all. CALLBACK_NULLNo callback mechanism. http://discusswire.com/error-code/windows-error-codes-and-solutions-pdf.html One thing I can think of is that the 'format' or 'type' (or whatever that member is called) is wrong.

That should probably be zero then. waveOut is easier to use (IMO -- but it depends a lot on what you want to do). more hot questions question feed default about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation

This method will stop playback if the last block has finished playing, otherwise it will start loading the next block on a separate thread.

You'll have to post the contents of your wfInfo struct for me to be sure...

Other than a Windows Defender issue (I removed it because it conflicts) I am very happy with it's features for the price! waveOutUnprepareHeader (): Releases a previously prepared WAVEHDR and data block. The WaveFile class is implements the IDisposable interface so that any associated WAVEHDR's can be disposed. Copy public bool Done { get { return !m_playing; } } protected bool m_playing = false; The Seconds property specifies the length of the audio in seconds.

Preload must be called prior to Start or it will return with an error. The WAVE_MAPPER constant can also be used as a device identifier. waveOutPause(): Pauses playback. fdwOpen Flags for opening the device.

WAVE_MAPPED_DEFAULT_COMMUNICATION_DEVICE If this flag is specified and the uDeviceID parameter is WAVE_MAPPER, the function opens the default communication device.

PLUS, the "info" chunk might not be immediately after the RIFF header like you appear to be assuming (there might be a comment chunk or something before it).

The sample code in this article demonstrates how to utilize the .wav file format to load and save PCM audio data that is compatible with the Waveform Audio Interface. If fdwOpen contains the CALLBACK_FUNCTION flag, dwCallback is a pointer to a callback function. Just as a test to see if you can get audio working. It's called as part of shutdown.

Do I have to send each block at a time or can I send the whole data at once? Use the handle to identify the device when calling other waveform-audio output functions.
