Alternatives to The Levelator: Modern Tools for Leveling AudioThe Levelator was once a near-mythical one-click tool for podcasters and audio editors who needed to tame uneven dialogue levels quickly and without fuss. While its simplicity made it indispensable, the tool hasn’t been actively updated in years, and modern workflows demand more control, better transparency, and higher fidelity. This article explores contemporary alternatives—both free and commercial—that improve on The Levelator’s core promise: consistent perceived loudness across a program while preserving natural dynamics and speech intelligibility.
What The Levelator did well — and where it fell short
The Levelator’s appeal came from its hands-off approach: drop in a WAV or AIFF file, wait, and get a more uniform level across speakers. It combined peak limiting, compression, and gentle normalization tuned for dialogue. However:
- It offered little user control or visual feedback.
- The processing could be opaque; users couldn’t tweak attack/release, threshold, or lookahead.
- Lacking updates, it doesn’t support newer formats, high sample rates, or integrate into modern DAW workflows.
- It sometimes introduced pumping or unnatural artifacts on more complex material.
Modern tools address those limits by offering detailed controls, meters that reflect loudness standards (LUFS), and features like per-speaker loudness matching, spectral noise gating, and transparent multiband gain shaping.
Key concepts to look for in modern leveling tools
Before comparing tools, here are the features that matter for leveling spoken audio:
- LUFS metering and loudness normalization (Integrated/Short/True Peak)
- Transparent compression: control over attack, release, ratio, and knee
- Lookahead limiting to prevent clipping while preserving dynamics
- Multiband processing for taming problematic frequency ranges without affecting clarity
- Adaptive/scene-aware algorithms that respond differently to speech and music
- Batch processing and DAW/host plugin support (VST/AU/AAX)
- Per-track or per-speaker gain matching and automatic gain control (AGC)
- Visual feedback: waveforms, spectrograms, gain-reduction meters
Free options
- Audacity (with plugins)
- Audacity is a free, open-source audio editor that, while not a one-click Levelator replacement, can achieve great results with built-in tools and addons.
- Use: Normalize → Compression → Limiter, or apply the “Loudness Normalization” (LUFS) plus third-party Nyquist plugins for speech leveling.
- Pros: Free, cross-platform, non-destructive editing.
- Cons: Workflow is manual and more time-consuming than one-click tools.
- ReaPack + ReaPlugs (Reaper’s free plugins)
- ReaPlugs (ReaComp, ReaEQ, ReaFIR) are excellent, transparent tools. ReaComp’s advanced controls make it possible to get natural results; ReaFIR can do dynamic noise gating and spectral cleanup.
- Pros: Highly flexible, very transparent, free.
- Cons: Requires learning and manual configuration.
- Auphonic Multitrack (free tier)
- Auphonic offers web-based and desktop services optimized for speech and podcasts. It automates leveling, loudness normalization (to chosen LUFS targets), adaptive leveling, noise and hum reduction, and metadata tagging.
- Pros: One-click automated processing tailored to podcasts; supports chapters and ID3 tagging.
- Cons: Free tier has limited processing minutes; cloud service may be a concern for some privacy-conscious users.
- Levelator alternatives in open-source projects
- Projects on GitHub may implement LUFS-based normalization or simple AGC. These require technical know-how but can be scripted into batch workflows.
Paid / Professional tools
- iZotope RX Loudness Control & Dialogue Isolate
- iZotope RX Suite includes powerful loudness-targeting modules, adaptive gain, and excellent speech-focused modules like Dialogue Isolate and De-rustle.
- Loudness Control: precise LUFS targeting and true-peak limiting.
- Pros: Industry-leading restoration and loudness tools, excellent UX, plugins and standalone.
- Cons: Costly; RX’s full suite is an investment.
- Auphonic Premium
- The paid tier lifts the processing-minute limits and adds features like higher-priority processing and more file format options.
- Pros: Same automated convenience as the free tier, with professional throughput.
- Cons: Ongoing cost.
- FabFilter Pro-L 2 / Pro-L 3 + Pro-C 2
- FabFilter’s limiter and compressor are studio standards. Combined with Pro-Q 3 (for surgical EQ) they allow detailed, transparent leveling.
- Pros: Transparent processing, visual feedback, excellent sound quality.
- Cons: Not automatic; requires manual setup.
- Waves Vocal Rider / Waves Vocal Rider 2
- Vocal Rider automates gain riding by adjusting level in real time to match a set target, preserving dynamics while achieving consistent perceived loudness.
- Pros: Extremely fast workflow for dialogue and vocals; integrates as a plugin in DAWs.
- Cons: Less control over mastering-style limiting; may require follow-up limiting.
- Sonnox Oxford Dynamics + Oxford Limiter
- High-quality dynamics and limiting with precise control and a musical sound suited to speech and broadcast.
- NUGEN Audio – SigMod and MasterCheck
- NUGEN’s tools offer LUFS targeting, True Peak limiting, and perceptual loudness control with broadcast-focused presets.
- Reaper (commercial, low-cost DAW) + ReaPlugs
- Reaper is inexpensive and scriptable; with ReaComp and ReaNormalize you can build automated leveling chains and batch-render large shows.
Workflow examples
- Quick podcast batch (minimal effort)
- Use Auphonic: upload files → choose LUFS target (e.g., -16 LUFS for podcasts) → enable noise reduction and adaptive leveling → export with metadata.
- DAW-based, hands-on approach
- Import into Reaper/Pro Tools/Logic → edit & clean (noise reduction, click removal) → apply EQ to clean up boxy frequencies → use transparent compressor (fast attack, medium release) → manual gain riding (or Vocal Rider) → final limiter (set true-peak limit -1 dBTP) → LUFS metering and adjust for target.
- Hybrid: automated + manual polish
- Run files through Auphonic or iZotope’s automatic leveling to get close → open in DAW for manual rides on problem spots → final limiter and LUFS check.
Which tool is right for you?
- Choose Auphonic if you want true one-click convenience and metadata support for podcast publishing.
- Choose Vocal Rider or a DAW-based compressor chain if you prefer staying in your DAW and want low-latency, realtime control.
- Choose iZotope RX for the best restoration and polishing toolset when dealing with noisy or problematic recordings.
- Use FabFilter or Waves for the highest-fidelity manual mastering when you need complete control.
Practical tips for better leveling results
- Record well: better source audio reduces processing needs—use consistent mic techniques and distances.
- Aim for good headroom: record peaks at least -6 dBFS to give processing room.
- Prefer LUFS targets over peak normalization for consistent perceived loudness across platforms.
- Use gentle compression ratios (1.5:1–3:1) for dialogue to retain natural dynamics.
- Combine automatic tools with spot manual gain rides for best results.
- Always check True Peak after limiting to avoid inter-sample clipping on streaming platforms.

Final thoughts
The Levelator’s simplicity inspired a generation of podcasters, but today’s options give significantly more transparency, control, and quality. If you want quick results with minimal fuss, Auphonic remains the closest spiritual successor. For more control and higher fidelity, combine DAW-based tools (Vocal Rider, FabFilter, ReaComp) with LUFS-aware metering and true-peak limiting. When dealing with noisy recordings, invest in iZotope RX’s restoration modules before leveling.
If you want, tell me your platform (Windows/macOS/Linux), budget, and typical workflow (single-speaker interviews, multi-guest remote recordings, noisy environments), and I’ll recommend a tailored toolchain.
