Why your guitar sounds delayed on PClatency, explained and fixed

TL;DR — the answer

Kill Bluetooth audio first — it adds 100–200ms alone. Then use Chrome/Edge, wired headphones, and an interface over the laptop mic input. Under ~10ms feels instant.

What latency actually is

Every digital audio path buffers: your guitar signal is chopped into small chunks, processed, reassembled. Buffer too big and you hear yourself late — the musical equivalent of a laggy video call. Under ~10 milliseconds it feels instant; over ~20ms your timing fights itself.

The usual suspects, in order

  • 1 · Bluetooth headphones/speaker

    The biggest single cause — BT alone adds 100–200ms. Wired headphones fix more than any setting will.

  • 2 · Browser choice

    Chrome and Edge expose the lowest-latency audio path. Firefox is fine; Safari is fine; the difference is real but smaller than BT.

  • 3 · The input device

    A proper interface processes audio in dedicated hardware; the laptop mic input shares a busy path. Interface → measurable improvement.

  • 4 · Sample rate mismatch

    If the interface runs 44.1kHz and the OS resamples to 48kHz, extra buffering sneaks in. Match them.

  • 5 · CPU contention

    A video call, a game, thirty tabs — audio loses CPU priority easily. Close what you're not using.

Measure it, don't guess it

In SOWND's Dial In room, the telemetry strip shows live latency. Change one thing at a time — go wired, switch browser, pick the interface input — and watch the number drop. Under 10ms and you'll stop thinking about it, which is the point.

Quick answers

  • Why is my guitar delayed through the computer?

    Audio buffering — the signal is processed in chunks. Bluetooth audio is the most common big cause (100ms+); browser, input device and CPU load add the rest.

  • How much latency is too much for guitar?

    Under ~10ms feels instant, 10–20ms is playable, over ~25ms most players feel the delay and timing suffers.
