How to Increase Gain in Iracing Audio

Answering how to increase gain in iRacing audio - quick steps to raise engine, voice, and UI levels. For iRacing drivers who want to fix this issue fast now.

If you’re asking how to increase gain in iracing audio, the short answer is: use iRacing’s master and individual channel sliders, check Windows sound levels, and raise your audio interface or headset gain. You’re in the right place — below are the clear steps to fix it fast.

Quick Answer: how to increase gain in iracing audio

Open iRacing’s Options > Sound, raise the Master volume and the specific channel (engine, cockpit, spotter, voice). If that’s still low, raise Windows app volume for iRacing, increase your audio interface/headset gain, or change the output device. These three places solve most problems.

What’s Really Going On

iRacing mixes several audio channels (engine, cockpit, spotter, voice, UI). The in-sim sliders control the relative and master volume. If audio sounds low, the cause is usually one of three things: the in-sim master or channel sliders are low, Windows or your audio device is limiting the output, or your headset/interface gain is set too low. Fixing the right layer restores proper loudness.

Step-by-Step Fix

  1. Open iRacing and go to Options > Sound. Set Master Volume to 80–100% to avoid clipping and ensure room to adjust channels.
  2. Increase the specific channels you want (Engine, Cockpit, Spotter, Voice) to around 70–90% depending on preference. Test in session sound.
  3. In Windows, right-click the speaker icon > Open Volume Mixer and make sure iRacing’s app slider is at or near 100%.
  4. If you use an external DAC, USB audio interface, or sound card, open its control panel and raise the output gain or volume. Some devices have a hardware knob—turn it up.
  5. For headsets with inline volume or software, increase that level. Wireless headsets sometimes use battery-saving low volume—check their app.
  6. If you hear distortion after raising gain, lower the in-sim master slightly and raise only the offending channels, or reduce Windows/driver boost to remove clipping.

Extra Tips / Checklist

  • Restart iRacing after changing output device in Windows so the sim detects it.
  • Disable Windows “Enhancements” or “Loudness Equalization” if they reduce perceived gain.
  • Use 2-channel stereo if multi-channel routing causes low levels to some channels.
  • If using voice chat (Crew Chief, Discord), check their individual volume sliders; these mix separately.
  • Update audio drivers and iRacing — old drivers can change behavior.

FAQs

Q: Why is my engine volume low but voice is loud?
A: Channel sliders in iRacing control each sound. Raise the Engine or Cockpit slider in Options > Sound while keeping Voice lower.

Q: iRacing is loud in-game but my headset is quiet overall — what now?
A: Check Windows volume mixer and your headset or DAC gain. Also confirm the correct output device is selected in iRacing.

Q: I raised master volume and got distortion. How to fix?
A: Reduce Master a bit and raise only the channels you need. Also lower Windows “boost” and confirm no hardware preamp is clipping.

Q: Does sample rate or audio format affect gain?
A: Not usually. But mismatched sample rates between Windows and your device can cause odd behavior—match them in sound settings.

Short Wrap-Up

To increase gain in iRacing, raise the in-sim master and channel sliders, check Windows/app volumes, and boost your headset or interface gain. Test changes in a practice session and tweak only the channels you need to avoid distortion. If it still feels wrong, check drivers and device settings next.
