Streaming Loudness Explained
Loudness Basics
When you upload music to services such as Spotify, Apple Music or YouTube Music, the platform applies automatic loudness normalization so every track sounds consistent. Understanding the metrics that drive this process is essential if you want your mixes to come out loud, clear, and compliant. This guide breaks down the key loudness standards, explains how they apply in Australia, and shows how Jovytensor’s mastering services help you meet them.
What Loudness Is and Why It Matters
Loudness is a perceptual measurement of how we hear sound intensity. Unlike peak level, loudness considers the ear’s varying sensitivity across frequencies and the duration of sound. Streaming platforms normalise loudness using LUFS (Loudness Units relative to Full Scale) so that tracks play at a uniform perceived volume. A track that is too loud can trigger clipping and distortion, while a track that is too quiet will feel weak. Mastering engineers therefore target the correct loudness to maximise listening comfort.
Key Loudness Standards in the Music Industry
- ITU‑BS.1770‑4: Global standard for loudness metering, underpins LUFS calculations.
- European Broadcasting Union (EBU) R128: Requires tracks to be around ‑23 LUFS for broadcast.
- Spotify: Targets ‑14 LUFS (–14 LUFS) for most streams; uses a 1‑second window.
- Apple Music & YouTube Music: Aim for ‑16 LUFS, using a 3‑second window.
- AS 4801:2017 (Australia): Defines loudness requirements for commercial radio and broadcasts, aligning with EBU R128.
For digital distribution, the most common requirement is the “–14 LUFS” target. However, many labels and streaming services also enforce a maximum true‑peak of –1 dBTP to avoid clipping after loudness processing.
Why Brisbane‑Based Clients Must Check Levels Early
In Brisbane, local broadcasters and radio stations often use the Australian Broadcasting Corporation (ABC) standards, which reference the EBU R128 level of ‑23 LUFS. If your track is mastered for streaming at ‑14 LUFS, it may sound uncomfortably loud on radio. It is therefore wise to master two versions: a streaming‑optimized mix and a radio‑ready version. Our studio provides both options in a single session, saving you time and cost.
How to Measure and Verify Loudness
Use a reliable LUFS meter such as Metronom or Avid Pro Tools with the ITU‑BS.1770‑4 plugin. Set the window to 3 seconds and record the integrated loudness. Compare the result against the target:
| Platform | Target LUFS | True‑Peak Limit |
|---|---|---|
| Spotify | –14 LUFS | –1 dBTP |
| Apple Music | –16 LUFS | –1 dBTP |
| YouTube Music | –14 LUFS | –1 dBTP |
| Australian Radio (ABC) | –23 LUFS | –1 dBTP |
If your track falls outside the target range, adjust the master bus gain, apply subtle compression or limiting, and re‑meter until you hit the desired level.
Common Mistakes to Avoid
- Saturation before limiting: Excessive harmonic distortion raises peak levels without increasing loudness, causing a “loud but distorted” feel.
- Ignoring mid‑range frequencies: Loudness meters under‑weight low and high frequencies; ensure balanced EQ to avoid a “tinny” or “boomy” sound.
- Using a single‑point meter: Relying only on peak level diagnostics can hide loudness discrepancies. Always check integrated LUFS.
- Over‑compressing: Too much compression reduces dynamic range, making the track sound flat.
What We Deliver at Jovytensor
Our EP & Album Mastering service includes:
- Integrated loudness targeting (–14 LUFS or –23 LUFS per client request)
- True‑peak limiting to –1 dBTP
- Dynamic range optimisation with transparent compression
- Final WAV 24‑bit, 96 kHz masters and distributable MP3/FLAC files
- Detailed loudness report and export files for record labels
We store your project files for six months and can provide additional revisions within the first five business days after delivery.
Getting Started: From Stems to Loudness
Before you send material to us, read our How to Prepare Stems for Mixing guide. Clean stems make mastering smoother, and a well‑structured session helps us hit loudness targets faster.
Next Steps for Your Release
Once you have your mastered files, you can upload them to platforms such as Spotify, Apple Music, and Amazon Music. Ensure you follow each service’s specific upload guidelines—most require the master to be in WAV 24‑bit/96 kHz, with a maximum file size of 200 MB. Use the loudness report we provide to verify compliance before your release.
After delivery, you will receive a detailed folder containing the final WAV, MP3, and FLAC files, along with a PDF report summarising all loudness metrics. If you need an extra round of tweaks, simply submit the files back and we will apply the requested adjustments within the agreed five‑business‑day window.
