After using SoundID Reference for a few weeks and comparing it to my friends install of Sonarworks Reference 4. I have found the SoundID systemwide app to be unstable, requiring rebooting of the machine. As it drops the signal path. I have both windows 10 & 11. And use Presonus 68C, Audient ID44, UAD Apollo Twin. We tested all hardware with both apps, and found, Sonarworks Reference 4 to be better at implementing, and maintaining the signal path. The worst failure is with Audient ID44 Also, on both windows 10 & 11 systems the taskbar icon for SoundID Reference is not visible, why? As for vst, both apps work. Yet again, SoundID Reference had issues with handing off audio signal routing, from the vst back to systemwide. Removing Sonar works resolves all sound routing issues, and the systems are back to stable audio paths. prior to install. But that's not what and why I paid for the product. I have tried drivers: 5.0.3.130/ beta 5.1.0.39 and are now trying 5.1.0.72. And 5.1.0.72 still has no taskbar icon. At present SoundID Reference is less reliable than Sonarworks Reference 4, I hope that will change. Thats been my experience so far.
