About Audio Normalization

Audio normalization adjusts the overall level of audio to achieve consistent loudness standards, making your audio sound professional and broadcast-ready.

Why Use This Tool?

  • Achieve consistent loudness across podcasts, videos, and music exports without manually riding faders or guessing peak levels.
  • Protects against clipping while raising quiet passages, giving you a polished master ready for streaming services.
  • Built for quick compliance with LUFS targets so your content matches platform standards and avoids automatic volume penalties.
  • Simple, browser-based workflow that keeps private recordings local—no third-party uploads or account sign-ins needed.
  • Ideal for creators batching many files; you can normalize intros, ads, and full episodes with the same trusted settings.

Common Questions

  • Q: What LUFS target should I choose? A: Use -14 LUFS for streaming music and YouTube, -16 to -20 LUFS for podcasts, and -23 LUFS for broadcast TV.
  • Q: Does normalization change dynamics? A: Peak normalization only adjusts overall gain; loudness normalization may subtly reduce headroom but keeps dynamics intact compared to heavy compression.
  • Q: Should I normalize before or after mastering? A: Normalize near the end—after EQ and compression—so your tonal balance stays consistent.
  • Q: Will it fix clipping? A: It prevents new clipping but cannot repair already distorted peaks; re-record or use restoration tools if distortion exists.
  • Q: Can I batch multiple files? A: Yes, apply the same target loudness to intros, interviews, and ads to keep episodes cohesive.

What Normalization Does

  • Adjusts peak levels to optimal ranges
  • Ensures consistent loudness across tracks
  • Prevents clipping and distortion
  • Meets broadcast and streaming standards
  • Improves dynamic range and clarity

When to Normalize

  • Before uploading to streaming platforms
  • When mixing multiple audio sources
  • For podcast and broadcast content
  • To match levels in audio compilations
  • Before mastering and final output

Loudness Standards

  • Streaming: -14 LUFS for Spotify, Apple Music
  • Broadcast: -23 LUFS for TV, -16 LUFS for radio
  • Podcasts: -16 to -20 LUFS recommended
  • YouTube: -14 LUFS target level

Pro Tips & Best Practices

  • 💡 Leave 1dB of true-peak headroom (-1dBTP) to prevent inter-sample peaks from clipping during streaming transcodes.
  • 💡 Normalize dialogue and music separately, then rebalance so speech stays clearly above background tracks by 3-6dB.
  • 💡 If exporting for radio, check gating thresholds and momentary max levels to ensure compliance with broadcast specs.
  • 💡 Use short fades on intros and outros after normalization to avoid clicks and to match loudness ramps across episodes.
  • 💡 Keep a reference playlist at target LUFS to compare tone and loudness before publishing.

When to Use This Tool

  • Podcasters aligning interview segments, ad reads, and music beds so episodes play at a consistent level on every app.
  • Video editors preparing dialogue, VO, and soundtrack stems for social clips that need platform-ready loudness.
  • Musicians exporting demos or stems to collaborators who expect standard headroom and consistent gain staging.
  • Customer support or sales teams normalizing webinar recordings before uploading to knowledge bases or LMS platforms.
  • Streamers leveling game audio and mic input to avoid sudden jumps that distract viewers during live sessions.

Related Tools

  • Clean noisy tracks first with Noise Reduction so the loudness analyzer focuses on the main signal.
  • Shape tone using Audio Equalizer before normalization to maintain a balanced spectrum.
  • Add space after leveling with Reverb Effect without exceeding peak targets.
  • For creative emphasis, combine with Echo Effect on key phrases, then re-normalize for final delivery.
