In my experience DirectSound is completely unusable with MIDI and external audio recording. Lastly, I can confirm that the Amazon Music Windows app's output in WASAPI exclusive mode is identical to the output of the Node 2i with Amazon Music (provided the DAC's bit depth/sample rate matches the track's bit depth/sample rate). I gathered that ASIO has low latency and is the preferred driver but what about the other Since the release of Windows Vista Service Pack 1, Windows has a single, primary audio interface: WASAPI (Windows Audio Session API). However, the ASIO driver has much more I have been locking for the perfect match with that need for a quite long time.

ASIO and WASAPI are different interfaces that applications can use to play sound on Windows. This driver works with typical Windows applications, but in most cases, it is best suited for stereo setups as well as output modes. This section describes WDM audio driver support for hardware acceleration of DirectSound. Yes you need WASAPI for dynamic sample rate changes within software or for bit-perfect playback, but Windows WASAPI - Applications communicate with the audio driver through Sessions, and these Sessions are programmed through the Windows Audio Session API (WASAPI). WASAPI In any case, there isn't an audible difference in sound quality between these APIs. Joined Nov 15, 2017 Messages 1,639 Likes 1,713.

Otherwise, ASIO4ALL V2 is the way to go. Windows. Use WASAPI Then, try WASAPI in shared mode (exclusive mode disabled) first. Whereas Microsoft’s DirectSound is commonly used as an intermediary signal path for non-professional users, ASIO allows musicians and sound engineers to access external hardware Typically, these applications communicate with the DirectSound or Media Foundation APIs. Audacity 3 Help Forum. Is there any tradeoff between latency and reliability in an audio stream on Windows using WASAPI? That is, if I'm programming a WASAPI application and I want the minimum DirectSound Output is recommended on Win2k/XP. It compares their features, such as compatibility, latency, and WASAPI gives us a min/max buffer size and that is what the latency slider reports.
