You can use the Volume property to adjust the volume and subscribe to PlaybackStopped to determine when playback has stopped. You call Init to pass it the audio to be played, Stop to stop playback. Once you've created an instance of WasapiOut, you use it exactly the same as any other IWavePlayer device in NAudio. The default is currently set to a fairly conservative 200ms. So take care when adjusting this setting. This can be very useful for real-time monitoring effects, but comes at the cost of higher CPU usage and potential for dropouts causing pops and clicks. The lower the latency, the shorter the period of time between supplying audio to the soundcard and hearing it. This is only a request, and depending on the share mode may not have any effect. Stereo X/Y mic configuration captures perfect stereo imagesSame frequency and. You can also request the latency you want. Maximum Sampling Rate: 48 kHzCompatible with popular recording software. Event sync is the default and generally is fine for most use cases. Without, you simply sleep for a short period of time and then provide more audio. With event sync, you listen on an event for when WASAPI wants more audio. This governs the behaviour of the background thread that is supplying audio to WASAPI. You can choose whether to use eventSync or not.

Obviously this mode impacts on other programs wanting to use the soundcard. The benefits of this approach are that you can specify the exact sample rate you want (has to be supported by the sound card and usually cannot be less than 44.1kHz), and you can often work at lower latencies. If you choose AudioClientShareMode.Exclusive then you are requesting exclusive access to the sound card. Fortunately, since NAudio 2.1.0 WasapiOut in shared mode will automatically resample the incoming audio. This however does mean that the sound card will continue to operate at whatever sample rate it is currently set to, irrespective of the sample rate of audio you want to play. This is normally set to AudioClientShareMode.Shared which means you are happy to share the sound card with other audio applications in Windows. There are a number of other options you can specify with WASAPI.įirst of all, you can choose the 'share mode'. This is discussed in the enumerating output devices article. When you create an instance of WasapiOut you can choose an output device. Right click the speaker icon in the system tray (lower right corner), go to Sound Settings and then click on Manage sound devices.

WASAPI was introduced with Windows Vista, meaning it will be supported on most versions of Windows, but not XP. Step 2: enable exclusive mode for your audio device. I turned down the game graphics setting to it's lowest point but the results are the same. What's odd is that i stream a new game for 2 hours and not a single problem but when i reached the russian installation it's started using more of my CPU. Whenever i try to stream Rise of the Tomb Raider i get a warning message High CPU Usage Consider turning down settings.
