22 cze 2024 · USB 3.0’s superior data transfer speed results in lower latency compared to USB 2.0, ensuring that your recordings and monitoring are in sync and free from distracting delays. Jitter, the variation in the timing of a digital audio signal, can also affect audio quality.
18 wrz 2022 · Data polling: USB 2.0 vs USB 3.0. The only advantage the USB 3.0 protocol has that provides better performance is the way it handles data polling. That alone should reduce your audio latency by a few ticks. What’s the problem with USB 2.0 audio interfaces though? NOTHING.
5 mar 2020 · Indeed, USB 2.0 vs. 3.x doesn’t make a significant difference. Bandwidth is more than enough on USB 2.0. The new UR-C series offers slightly lower latencies in general though - given that the computer is capable of handling those.
Usb 2.0 has a latency of about 125 microseconds. Unlike 2.0, usb 3.0 is not a shared-bus system. Instead it uses a point-to-point link between the host and each device which can help decrease the latency by a significant amount (in terms of multiples, still not noticeable at all).
My favorite choice for small-scale recording is the RME UCX, which has 18 channels of input and 18 channels of output, along with software control of onboard DSP, with extremely low latency, and it works perfectly over USB 2.0. Less latency over USB than over firewire 400, even.
17 lis 2017 · There aren't much reasons for that, because USB 2.0 and 3.0 share lot of common characteristics for typical audio streaming implementation and unless more bandwidth is necessary (say networked audio or multiple MADI ports, where you can exceed 64 audio channels), it doesn't bring any benefits.
20 lis 2019 · USB 2.0 - High Speed, USB 3.0, and USB 3.1 Max Polling Rate: 8000 Hz *Keep in mind, however, that there are other factors that can impact peripheral performance, such as your operating system, and device drivers.
