  • Latency?

    I’m excited about using a voiceprint DI. I have a question, with the processing that is going on in the DI itself, is there any latency at all? Can you feel a delay?
    Thanks,

    The VPDI doesn't have any latency that I've noticed. Every other IR or similar type of technology that I've played has always had either latency or a general feeling of disconnect from the instrument. To me, the VPDI feels very immediate and responsive.

    I'm curious to hear from the others though.

      I also don’t feel any noticeable latency. However, as I’ve been experimenting mixing the VPDI with the direct signal from my guitar, I had to do some “advanced” signal routing and processing, which included delaying the direct signal by 0.6 milliseconds in order to sound good (subjective term) mixed with the output of the VPDI. Whether 0.6 ms is the latency of the VPDI, I don’t know, but I would be surprised if it was that low. It’s just what sounded good as I was experimenting. Might have more to do more with phase than delay in the signal. In any case, I want to be clear that I don’t see this in any way being a flaw with VPDI, just a reality of audio signal processing and mixing multiple sound sources. And I don’t “feel” any disconnect from the instrument - it feels responsive.

      Caleb, I would be interested to know if Baggs is willing to publish the latency of the VPDI. Because of the nature of digital signal processing, it must be greater than zero but is still probably really good. I can see marketing reasons for and against publishing it, as well as technical reasons (might be different depending on the amount of DSP the user is asking the pedal to do). I certainly am curious, and the pro-marketing argument would be that it is lower than competitors.

      In any case, the VPDI is a great product already, and adding the “Advanced Toolkit” options will increase its value. I also appreciate Baggs product support in the form of this online forum.

        I can look into it.
