VB-Audio's Forums

Yesterday and today morning, I noticed that my microphone had a ~2.25 second delay (by stopwatch) within Voicemeeter Banana (v2.0.6.8). The issue is temporarily resolved by selecting "Restart Audio Engine" from the menu.

My configuration is very simple:

• A1: MME: Realtek Digital Output

• HW Input 1: KS: wc4800_8205 (scarlet solo)

• Output on B1 with EQ applied

(Settings export: https://pastebin.com/x7yQB5gT)

When I clap by the microphone, the visualization bar on Hardware Input 1 jumps ~2.25 seconds later. After "Restart Audio Engine", the visualization reacts practically immediately.

I don't know what is triggering this delay or when exactly it starts. I have been using Voicemeeter Banana for years without an issue like this, and suddenly I have had this latency issue in the morning for the past two days. My PC has been running overnight, so it isn't caused on system-startup.

Please let me know if you have any ideas or if you need any logs to look at.

Voicemeeter cannot generate more delay than 3x the buffer sized used by the device.
so even if you have 1024 sample buffer (23.2 ms at 44.1 kHz - 21.3 ms at 48 kHz),
Voicemeeter won't generate more than 3x 1024 < 3x 24ms < 72ms

so if you have 2250 ms delay, it's mainly du to operating system, or audio stream transport or conversion outside of Voicemeeter.
2250 - 72 = 2178 ms are not generated by Voicemeeter.

Ok, thank you. I'll have to see what else I can troubleshoot then.
