How to Reduce Latency When Recording

To reduce latency recording at home, the two biggest levers are lowering your audio buffer size and using direct (hardware) monitoring so you hear yourself before the signal even reaches your computer. Combine those with good drivers and a tuned-up system and you can monitor with delay so small it feels instant.

Quick answer: Lower the buffer size to 64 or 128 samples while tracking, enable direct monitoring on your interface, use ASIO (Windows) or Core Audio (Mac) drivers, and free up CPU by closing apps and disabling heavy plugins on record-enabled tracks.

Why latency happens

Latency is the short delay between making a sound and hearing it back through your DAW. The signal has to be converted to digital, buffered, processed, buffered again, and converted back to analogue. Each stage adds time. When monitoring through software, this round trip can be large enough that singers and players hear themselves lagging, which ruins timing. For the full background, see what is audio latency.

1. Lower your buffer size

The buffer size is your main control. A smaller buffer processes audio in smaller, more frequent chunks, which cuts delay. While recording, drop to 64 or 128 samples. If you hear clicks or dropouts, step up to 256. Learn how the trade-off works in what is buffer size. Where to set it:

• GarageBand: Settings, then the Audio/MIDI tab, plus your interface’s control panel.
• Audacity: Preferences, then Devices, adjust buffer length.
• FL Studio: Options, then Audio Settings, set the Buffer length slider low for tracking.

2. Use direct monitoring

The single most effective fix is direct monitoring: your audio interface routes the input signal straight to your headphones in hardware, bypassing the computer entirely, so you hear yourself with effectively zero delay. Flip the monitor switch (often a Direct/Input vs Playback control) on your interface and mute the input track’s software monitoring in your DAW so you do not hear it twice. This lets you keep a high buffer for stable playback while still tracking comfortably. Most modern interfaces support it — see our audio interfaces hub.

3. Use the right drivers

Drivers matter enormously on Windows. Use the manufacturer’s ASIO driver for your interface rather than generic Windows audio, which carries high latency. On macOS, Core Audio is already low-latency and needs no extra driver. Keep your interface’s drivers and firmware up to date, and select the dedicated driver in your DAW’s audio settings rather than the built-in option.

4. Free up your CPU

A struggling CPU forces you into a larger buffer, which raises latency. Lighten the load so you can track at a small buffer without glitches:

• Close web browsers and background apps.
• Bypass or remove heavy plugins (reverbs, convolution, virtual instruments) on record-enabled tracks while you track.
• Freeze or bounce finished tracks so they no longer tax the processor.
• Disable wireless and power-saving features that can cause audio interruptions on laptops.
• Raise the buffer again when you switch from tracking to mixing.

5. Set monitoring up cleanly

Once latency is low, make sure your monitoring chain is tidy. Monitor on closed-back headphones while tracking to avoid bleed, set sensible levels with good gain staging, and confirm your interface is wired correctly using how to set up an audio interface. If you only ever hear a slight delay on plugin-heavy sessions, switch to direct monitoring and the problem disappears.

Quick checklist

1. Drop buffer size to 64 or 128 samples for tracking.
2. Enable direct monitoring and mute software monitoring on the input track.
3. Use ASIO (Windows) or Core Audio (Mac) drivers, kept up to date.
4. Close background apps and bypass heavy plugins while recording.
5. Raise the buffer back up when you move to mixing.

Frequently asked questions

What is an acceptable latency for recording?

Round-trip latency under roughly 10 milliseconds usually feels instant when monitoring a performance. Above that, performers begin to notice a lag. Direct monitoring removes the issue entirely because you hear yourself in hardware.

Will lowering the buffer size hurt my recording quality?

No. Buffer size only affects latency and CPU load, not the fidelity of the recorded audio. The captured file sounds the same whether you tracked at a low or high buffer.

Why do I still hear delay with direct monitoring on?

You are probably also monitoring through the DAW, so you hear both paths. Mute the software input monitoring on the record-enabled track so only the zero-latency hardware signal reaches your headphones.
