Audio Loudness, Dynamics, and Mastering Delivery Tools

Measure LUFS and true peak, normalize loudness, shape dynamics, and prepare podcast, broadcast, or music files for cleaner audio delivery in one mastering-focused hub.

This hub focuses on the final audio checks and corrections people usually need before they publish, syndicate, upload, or hand off a finished file. It brings together loudness metering, LUFS and peak normalization, dynamic-range inspection, compression, limiting, broadcast-style dynamics control, and batch leveling so users can move from a raw mix or inconsistent export to audio that is easier to deliver across podcast, streaming, and review workflows.

Why this hub exists

Audio delivery problems are rarely caused by one number alone. Teams usually need to check LUFS, true peak, crest factor, and level consistency together before a file is ready for podcast, broadcast, or platform upload.

Keeping meters, reports, normalizers, compressors, limiters, and batch-leveling tools in one place makes it easier to move from “this sounds off” to a repeatable mastering and delivery fix.

The included WAV, MP3, FLAC, AAC, OPUS, and raw PCM samples let users compare loudness and dynamics behavior across common listening and delivery formats before they touch client masters or published episodes.

Featured Tools

Analyze audio to find true peak level

Audio Dynamic Range Meter

Compute dynamic range via crest factor (peak minus RMS)

Audio Dynamic Range Report

Analyze and report on the dynamic range of an audio file

Audio Peak Detector

Find the peak volume level in an audio file

Audio Loudness Normalize (LUFS)

Normalize audio to a target loudness (LUFS) using FFmpeg loudnorm

Audio LUFS Normalizer

Normalize audio to broadcast/podcast LUFS standards

Audio Normalize (Peak)

Normalize audio to a target peak level (e.g., -0.1 dB) using two-pass max-volume detect

Audio RMS Normalize

Normalize audio based on its RMS level

Batch Audio Normalize

Normalize multiple audio files to a target peak level with consistent volume across the batch

Audio Compressor

Apply dynamic range compression with configurable threshold, ratio, attack/release, and makeup gain

Audio Multi-band Compressor

Apply compression to specific frequency bands (3-band crossover + compressors)

Audio Limiter

FAQ

What can I do in this hub?

You can measure LUFS and true peak, inspect dynamic range, normalize loudness or peak level, and apply compression, limiting, gating, or batch leveling before publishing or delivery.

Who is this hub useful for?

It is useful for podcast editors, audio engineers, video teams, course creators, and anyone preparing spoken-word or music files for streaming, review, or broadcast-style delivery.

How should I start?

Start with the LUFS meter, true peak meter, or loudness report to see where the file currently sits. Then normalize to the target level and only add compression, limiting, or noise gating when the delivery goal calls for tighter control.
