Mastering, Answered.
What is online mastering software?
Online mastering software lets you finalize a finished mix entirely in the browser. FNLZ Studio applies a professional mastering chain — EQ, compression, stereo enhancement, loudness, and limiting — to produce a release-ready master without external studio sessions.
Can I master songs online with FNLZ Studio?
Yes. Upload your finished mix and FNLZ Studio analyzes loudness, spectral balance, dynamic range, and stereo image, then delivers a streaming-ready master you can preview and export in minutes.
What audio formats does FNLZ Studio support?
FNLZ Studio supports WAV, MP3, AIFF, and FLAC for upload, and exports 24-bit WAV, 16-bit WAV, and 320kbps MP3 — formats accepted by every major streaming platform, distributor, and broadcast standard.
Can I upload WAV files?
Yes. WAV is the recommended upload format for the highest fidelity. MP3, FLAC, AIFF, and M4A are also supported. Upload your finished stereo mix.
Is FNLZ Studio good for independent artists?
Yes. FNLZ Studio is built for independent artists, producers, and engineers who need label-quality sound without the cost or wait of a traditional mastering studio.
Can producers export release-ready masters?
Yes. Producers and engineers use FNLZ Studio for album mastering, level-matched comparisons, and high-volume professional release work with WAV and MP3 deliverables.
Does FNLZ Studio work in the browser?
Entirely. FNLZ Studio is a browser-based audio engineering platform — no installs, no plugins. Upload, preview, and export from any modern browser.
Can I hear my master before I pay?
Yes. Upload your song and FNLZ Studio masters the whole track for free (one a day), so you can hear all of it next to your original at matched loudness. Your first download is free; after that, unlock any master for $17, or subscribe from $39/month for 4 masters.
Can I master a whole album or EP?
Yes. Album mastering on the Pro plan masters every track with shared settings and one loudness plan, so the record plays at a consistent level while quieter songs keep their place.
