Measure the real loudness of every AudioClip from its samples — LUFS, true peak, distance from target — then do the same for your mixer buses. Editor-only, and it never modifies your clips.Editor-only tool with no runtime code, so it is independent of the render pipeline and works the same under Built-in, URP, HDRP and a custom pipeline. Needs Unity 2022.3+ and Unity's own Audio module (com.unity.modules.audio); without it the tool switches itself off quietly instead of filling the console, and a one-click Setup window enables it. No third-party dependencies.The ear is not a measuring instrument. It adapts in seconds, it depends on your monitors and your room, and it cannot give you a number you can act on. Quick Audio Level Pro reads the actual samples of every AudioClip in your project and tells you, in numbers, which sounds clip, which get buried, and which are out of step with the sounds beside them — then does the same for the mixer buses they play through.WHAT EYES AND EARS MISS• A clip whose every stored sample sits at −5.6 dBFS can still reach −2.5 dBTP when it plays, because the signal passes between samples. Nothing in Unity shows you this.• A sound can be 21 dB under the rest of your game and simply never be heard.• Your files can all be safe while the mix clips anyway, because the bus adds gain after the fact.• Two footsteps 12 LU apart sound like a bug; an explosion 12 LU above a footstep is correct. Loudness only means something relative to the sounds beside it.WHAT IT MEASURES• Integrated loudness — ITU-R BS.1770-4, K-weighted, two-stage gated (LUFS)• True peak — 4x oversampled, catches peaks between samples (dBTP)• Distance from target, and the exact dB change that fixes it• Folder consistency — the spread inside a folder and the clips that break it• Head and tail silence padding — wasted memory and late-sounding one-shotsMIXER BUSESFiles are only half the problem. The window maps clips to the mixer group they are routed through, rolls the measured loudness up per bus, and flags what only appears there: a bus whose content clips once the group gain is applied even though every file is safe, two buses so close in loudness that one masks the other, and a bus nothing is routed to. A Match target button shows the gain change before it is applied, never after.Unity stores no link from a clip to a bus — the link only exists on an AudioSource — so the tool finds it by scanning prefabs. A clip with no source is reported as not routed rather than guessed at.MEASURED, NOT ASSUMEDEvery number comes from sample data. Nothing is read from an import setting, which is why the report can disagree with what your project claims — and disagreeing is the only reason it is worth reading. The K-weighting filters are re-derived at each clip's own sample rate, because the constants everyone quotes are for 48 kHz and shift the answer on a 44.1 kHz clip.COMPRESSED CLIPSMeasured, not assumed: AudioClip.GetData returns silence for CompressedInMemory, Streaming, and anything with Load In Background on — and in those cases loadState still reads Loaded, so it cannot be trusted as the signal. Four of six ordinary import configurations would make a naive tool call your loudest clip silent. This tool decompresses such a clip temporarily, measures it, and puts your import settings back exactly as they were, even if something throws in between. When it still cannot read the samples it says so rather than reporting zero.SAMPLE CLIPSSix deliberately mismatched clips with a written note of what the report should say about each: one that clips at +2.1 dBTP, one 21 dB under target, one with 0.80 s of silence before the sound, and two UI sounds 0.7 LU apart that are correctly left alone.CLEAN AND SAFE• 100% Editor-only — nothing ships in your build, zero runtime overhead• Namespaced code (Krykftn.QuickAudioLevelPro) — no global scope pollution• Without Unity's Audio module the tool switches itself off quietly instead of filling your console, and a one-click Setup window turns it back onREQUIREMENTS• Unity 2022.3 LTS or newer• Unity's Audio module (com.unity.modules.audio) — part of UnityHONEST LIMITSLoudness is judged inside a folder, not across the project, so organise your audio into folders that mean something or the consistency check has nothing to compare against. The bus view only sees clips referenced by a prefab's AudioSource; sounds played purely from script cannot be traced this way and are listed as not routed. True peak uses 4x oversampling with a 16-tap windowed kernel — accurate to about a tenth of a dB, enough to catch clipping, not a mastering-grade meter. Measuring reads every sample of every clip, so scan a folder rather than everything on a large project.Features:• Integrated loudness per clip, ITU-R BS.1770-4, with K-weighting biquads re-derived at each clip's own sample rate• True peak by 4x oversampling — catches clipping that happens between samples• Per-clip checks: over the ceiling, below or above target, out of step with its folder, head and tail silence padding• Folder summaries with mean and spread• Mixer bus view: clips mapped to their group, loudness rolled up per bus, bus-only mistakes flagged, Match target suggestion• Reads compressed and streamed clips that Unity otherwise returns as silence, and restores import settings exactly• Six sample clips with a written explanation of the expected reportSupported OS: Windows, macOS, Linux (editor tool)Technical notes:• 100% Editor-only — no runtime code ships in a build• Namespaced under Krykftn.QuickAudioLevelPro• Editor assembly gated by an assembly-definition constraint on com.unity.modules.audio, so a project without it gets zero compile errors• Measuring never modifies a clip; import settings are restored even if an exception is thrown• Unity 2022.3 LTS or newerDocumentation: included as README.md and Documentation/Documentation.mdAI assistance was used while making this package, and here is exactly where.Code: an AI coding assistant helped write and review the C# source. The measurement maths was verified against synthesised reference tones whose correct answer is known in advance - a 1 kHz tone at -20 dBFS measures -19.993 LUFS, a 997 Hz tone measures -20.000, and a 100 Hz tone at the same level measures -21.827, which is the proof that the ITU-R BS.1770 K-weighting is really being applied rather than a plain RMS. Every one of those runs was executed in the Unity Editor before submission.Text: the README, the documentation and this store description were drafted with AI assistance and then edited by hand for accuracy.Images: no image content is AI generated. Every screenshot is a real capture of this tool running in the Unity Editor, and the levels shown in it are measured from the sample data of the clips in that project. AI was used only to place those real screenshots on a background and to write the caption text around them.Nothing in the package generates content, audio or otherwise. It is an editor-only measurement tool: it reads each AudioClip's samples, computes loudness and true peak from them, and reports "could not read" rather than a number when a clip's import settings prevent it from being decoded.
