Loudness Report

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

02 ⬡ AudioQC — desktop

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. Peak-safe: respects a true peak ceiling by reducing gain — no limiting or compression.

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

Creative work is for creatives

The computer should do the boring work — not the other way around. AudioQC automates the delivery chores that eat afternoons: loudness checks, format conversion, metadata, silence trimming. Nobody got into audio to fill in metadata fields.

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

Measured to spec

Loudness per ITU-R BS.1770-4, true peak with 4× oversampling, loudness range per EBU R128. The numbers you see here are the numbers a broadcast QC check will read — cross-check against any meter.
