isochronous

About this tag
The term isochronous on WindowsForum.com primarily appears in two contexts. One is the recent introduction of Bluetooth LE Audio support in Windows 11, which enables isochronous data streams for high-fidelity stereo audio and super-wideband voice simultaneously, overcoming the classic Bluetooth compromise. The other context involves older IEEE 1394 (FireWire) isochronous transfer issues in Windows 7 and Windows Server 2008 R2, where bugs caused slow performance, system hangs, or failed transfers when accessing streaming data. These threads discuss hotfixes and workarounds for isochronous device problems on the 1394 bus.
