  • On Windows 10, Windows 8, Windows 7 and Vista:
    • Windows DirectSound may by default have only slightly lower latency than MME.
    • Selecting Windows DirectSound or Windows WASAPI and enabling both "Exclusive Mode" boxes in Windows Sound allows Audacity to request audio direct from the device without resampling.
  • On Windows XP (given a recent computer), DirectSound's much shorter path to the hardware should produce much lower latency than MME.
Peter 29Jan15: Commenting this out as WDM-KS will not be included in the next release

ToDo-2P will need to restore this if and when WDM-KS aupport is added back to Audacity.

  • On Windows 10, Windows 8, Windows 7 and Vista:
    • Windows DirectSound and WDM-KS may by default have only slightly lower latency than MME. However WDM-KS can produce latencies as low as 5 milliseconds if you reduce "Audio to buffer" in Recording Preferences as described above.
    • Selecting Windows DirectSound or Windows WASAPI and enabling both "Exclusive Mode" boxes in Windows Sound allows Audacity to request audio direct from the device without resampling.
    • When using WDM-KS, the currently playing application has exclusive access to the audio device irrespective of Windows "Exclusive Mode" settings. See the Wiki page for Windows 7 for more explanation.
  • On Windows XP (given a recent computer), WDM-KS's and DirectSound's much shorter path to the hardware should produce much lower latency than MME.
