Loudness Report

Analyse integrated LUFS, true peak and dynamic range. Checks Spotify, Apple Music, YouTube and podcast targets instantly.

Scan files for clicks. Visual waveform with markers at every issue. Timestamped CSV export.

Convert audio and video files to WAV, MP3, µ-law and A-law. Resample, change bit depth, mono/stereo. Batch download as zip.

Drop files, trigger sounds, adjust volume. Test how your audio works together. Keyboard shortcuts included.

Stamp artist, copyright, year, URL and more onto hundreds of files at once. WAV, MP3 and AIFF. Fill in once, deliver professionally.

Silence Trimmer

Auto-strip leading and trailing silence from batch files. Set threshold, padding and trim mode. Shows exactly how much time and space was saved per file.

Loudness Normaliser

Analyse and gain-adjust files to hit a target LUFS. Presets for Spotify, Apple, YouTube, Podcast and EBU R128. True peak limiting included.

08 ⬡ AudioQC — desktop

Drop loops and stems into a clip pool, drag them into a lane to audition arrangements. Build track structures like lego blocks.

09 ⬡ AudioQC — desktop

Audio Inspector

Drop folders to instantly see sample rate, bit depth, channels, duration, bitrate and file size — grouped by folder. Sort and export to CSV.

10 ⬡ AudioQC — desktop

Chain multiple processes in one pass — trim silence, fade, normalise to LUFS, stamp metadata. Drop entire folder structures and process everything in seconds.

11 ⬡ AudioQC — desktop

QC null test — verify that your stems phase-accurately sum to the master. Detects residual down to −160 dBFS. Pass/Fail + per-stem report.

12 ⬡ AudioQC — desktop

Apply fade in and fade out to hundreds of files at once. Drop entire folders and keep the structure intact. Linear, exponential, logarithmic or S-curve.

About

Why this exists

01

Built by a sound designer

I wanted to spend less time on QC and more on creative work — so I built the tools I kept wishing existed. Quality control before client delivery, batch processing that keeps your folder structure, batch loudness checks in seconds. If it's here, it's because I actually use it.

02

Nothing leaves your machine

Everything runs in your browser or locally on your Mac. No uploads, no API calls, no cloud. We don't even have a server to send it to.

03

No friction

No account. No subscription. No trial period. No file limits. Open a tool, do the work, close the tab. That's it.

04

More coming

I'm building a desktop app for heavier workflows — batch processing entire libraries, full format support, offline use. The web tools will always be free.

Coming soon

AudioQC
for Mac

The web tools use the Web Audio API — which is great, but has real limitations. The desktop app uses FFmpeg under the hood. No format restrictions, no bit depth compromises, no browser quirks.

⚡ Old school. Buy once, own forever. No subscription.
