Windows 10

Win10 support FLAC, ALAC and MKV.
A welcome addition.

According to PCAudioLabs latency has improved.

In Windows 7, the lowest latency numbers achieved were at a buffer size of 220 samples for a latency of 5ms.

In Windows 8, the lowest latency numbers achieved were at a buffer size of 179 samples for a latency of 4ms.

In Windows 10, the lowest latency numbers were at a buffer of 132 samples for a latency of 3ms.

According to SonciState:

Audio Core Optimisation - it will now be possible to define and isolate all the core audio processing to a single core, meaning no other processes will be able to interrupt the stream.

Windows 10 Creators Update (April 2017) added a native USB Audio Class 2 Driver.

Archimago measured its performance and didn’t find any anomalies.

The UAC2 standard was finalized in 2009.

A pity it took MS 8 years to implement it.

It is playback only. The recording part of UAC2 is not implemented.

Audio settings


As little has changed, consult the Windows 7 section for the audio settings.


Direct Sound

Windows default audio engine is most of all built for speed.
It will do sample rate conversion requiring few resources but it measures poorly.
