Online Mastering — frequently asked questions
How much does online mastering cost?
€3.99 per mastered track. Your first master is free with code MASTERFREE2. No subscription, no signup fee, no minimum commitment. Just pay per master.
Is online mastering as good as a professional mastering engineer?
For most independent releases and streaming-first tracks, modern AI-powered online mastering delivers pro-quality results. HoRNet's adaptive engine analyses your mix in real time and applies purpose-built preset chains for six different use cases, from vintage analog to streaming-ready. It's not a replacement for a top-tier human engineer on a Grammy-level release, but for €3.99 per track it's a serious option for independent producers and most streaming releases.
Can I master my music online for free?
Yes. HoRNet offers a free 20-second preview of every preset before you pay, and your first full master is free using code MASTERFREE2. After that, €3.99 per mastered track.
Does it work for streaming platforms like Spotify, Apple Music, and YouTube?
Yes. The Streaming preset targets the loudness standards used by Spotify (-14 LUFS integrated), Apple Music (-16 LUFS integrated), and YouTube. The target is selected when you pick the preset, so you don't have to set LUFS numbers manually.
What's the difference between AI mastering and online mastering?
AI mastering uses machine learning to analyse and process audio. Online mastering can use AI, traditional DSP, or both. HoRNet combines adaptive analysis with purpose-built preset chains (Vintage, Modern Analog, Modern Digital, Contemporary Extreme, Streaming, Transparent), all running server-side in a browser-based interface. The Modern presets include the same AutoWidth stereo processing and 3-band Thrust multiband design featured in HoRNet's commercial plugins.
Do I need to install anything or create an account?
No installation — it runs in any modern browser (Chrome, Firefox, Safari, Edge, mobile). You can upload and preview without an account. The account is created automatically when you check out, so the mastered file can be delivered to you and re-downloaded later.
Choose your favorite style for your master
Vintage Mastering
Recreates the warm, musical character of legendary analog mastering suites from the 1970s and 1980s. This style intelligently applies harmonic saturation, smooth tube-style compression, and gentle high-frequency roll-off that adapts to your track’s dynamics. Perfect for rock, jazz, blues, and any genre seeking that authentic vintage warmth and musical glue that made classic records so compelling.
Modern Analog
Delivers the best of both worlds – contemporary clarity with analog musicality. Our system analyzes your audio and applies adaptive analog-modeled compression and EQ curves that respond to your track’s frequency content and dynamics. Ideal for pop, indie, alternative, and acoustic music that needs modern punch while retaining organic, musical character that breathes with your performance.
Modern Digital
Focuses on surgical precision and transparency while maintaining musicality. The system intelligently applies clean compression and precise frequency shaping that adapts to your audio’s spectral content. Perfect for electronic music, pop productions, and any genre requiring crystal-clear definition, tight low-end control, and pristine high-frequency detail without coloration.
Contemporary Extreme
Designed for maximum competitive loudness and impact on small playback systems. Our adaptive algorithms analyze your track’s characteristics to apply intelligent compression and limiting that maintains clarity at extreme levels. Specifically crafted for EDM, trap, and modern electronic genres that demand aggressive loudness to cut through on smartphones, earbuds, and portable speakers while preserving punch and definition.
Streaming
Designed for delivery to streaming platforms. Targets −14 LUFS so the track is not turned down by the platform’s loudness normalization and keeps its full dynamic range and headroom. Light processing: no thrust, no analog emulation, just a very gentle auto-EQ, mild tonal balance and a discrete dynamics stage that only catches the excesses. The result is a clean, transparent master that is already compliant with streaming-platform loudness.
Transparent
Minimal processing for dynamic, genre-sensitive material: acoustic, jazz, classical, voice-over, where the priority is to
preserve the natural dynamics instead of “smoothing” the signal. No thrust, no stereo widener, no analog emulation: just a light EQ and the lightest possible dynamics stage to keep peaks under control without compressing the performance. The auto-EQ runs at the bare minimum for the most neutral tonal balance possible.
