AutoSonic – Key features

  • Press Listen while the sound plays (footsteps, voices, gunshots, music).
  • AutoSonic picks the EQ — you don’t need to know frequencies.
  • Simple modes: Footsteps, Ambience, or Balanced.
  • One-click Apply to Equalizer APO for system‑wide changes.
  • Save presets per game/headphones and swap instantly.

How it works

AutoSonic listens to a short clip of whatever you’re hearing and automatically suggests a small set of tweaks. Most people just hit Listen → Apply. If you want, you can fine‑tune the sliders before applying.

Requirements

  • Windows 10/11
  • Equalizer APO recommended (it’s what makes the changes system‑wide). You can also export the suggested EQ for other tools.

Quick start (≈60 seconds)

  1. (Recommended) Install Equalizer APO so the EQ applies system‑wide.
  2. Open the EAPO Configurator, tick your playback device (headphones/speakers), and reboot if Windows asks.
  3. Run AutoSonic on Windows.
  4. Choose a simple mode: Footsteps, Ambience, or Balanced.
  5. Play the sound you want boosted (e.g., run around for footsteps), click Listen for ~5–15 seconds, then click Stop.
  6. Click Apply. Done — your system audio is now tuned. (Optional: tweak sliders first.)
Good to know: AutoSonic only listens to your system audio and writes EQ settings. It doesn’t add an overlay and doesn’t hook into games.

Controls & hotkeys

  • Listen / Stop — capture a short sample of system audio
  • Action — Boost / Reduce / Custom
  • Preamp — a safety slider to prevent distortion (optional)
  • Apply — push the generated block to Equalizer APO
  • Hotkeys: L Listen • S Stop • A Apply • R Reset • H Help

Suggested workflow

  1. Start your game/music in the exact scene you care about (e.g., run around to generate footsteps).
  2. Choose the matching Listen mode:
    • Footsteps/Transient — short repeating sounds (footsteps, reloads)
    • Sustained/Ambience — constant sounds (engine hum, music bed)
    • Generic — balanced
  3. Capture 10–20 seconds. Repeat once or twice if the scene is inconsistent.
  4. If something sounds harsh or muddy, try a small Reduce first, then add a little boost for clarity.
  5. Small changes usually sound best. If it distorts, lower Preamp.

Presets

  • Save preset… stores your current suggestions so you can swap between games/headphones.
  • Load preset… restores a saved curve and its settings.
  • Presets are portable; you can share them by sending the preset file.

Equalizer APO setup (must-read)

  • Equalizer APO applies EQ at the Windows audio level. If AutoSonic seems to “do nothing”, it’s almost always because the device isn’t enabled in the Configurator.
  • After enabling your device, Windows may require a reboot for EAPO to attach correctly.
  • If you change your default playback device (USB headset / DAC / Bluetooth), re-run the Configurator and enable the new device.

Tips

  • For the best results, capture the exact situation you care about (e.g., the same map/scene).
  • Short capture (5–15s) is usually enough. If the scene is chaotic, record a little longer.
  • If you get “No audio captured”, make sure audio is playing and try a different Analyzer source in AutoSonic.
Advanced (optional) — why results can differ

Different scenes/music have different dominant frequencies, so AutoSonic may suggest slightly different EQ each time. If you want consistency, record 20–30 seconds and repeat once — then pick the best result.

Troubleshooting

  • No change after Apply? Confirm Equalizer APO is installed, your playback device is enabled in Configurator, and reboot once after enabling.
  • No audio captured? Make sure sound is playing and your Windows default playback device is correct; then try another Analyzer source.
  • Weird results? Record longer (20–30 seconds) and use a more consistent scene; reduce Gain and increase Preamp headroom.
Privacy: AutoSonic processes audio locally. Nothing is uploaded.

FAQ

Does it need internet?

Activation requires a quick online check. After activation, AutoSonic runs locally and only needs occasional validation (like your other apps).

Do I need Equalizer APO?

Recommended for system-wide EQ. AutoSonic can still export a standard Preamp + PK band block if you use another EQ tool.

What EQ format does it export?

Equalizer APO style filter lines (Preamp + PK bands with Fc/Gain/Q). You can paste them into your EAPO config or adapt them to other EQ stacks.

Why are my results different each time?

Different scenes/music have different dominant frequencies. For best results, capture 20–30 seconds of the exact scenario you want to tune for, and repeat once for consistency.

No audio captured?

Make sure audio is playing and your default playback device is correct in Windows. Then try a different Analyzer source option in AutoSonic.
