Mastering used to mean a dedicated studio or a chain of expensive plugins. You can now do a clean, musical master in your browser using a modeled tape engine plus proper metering. This guide walks through a practical, repeatable workflow and the targets to aim for.
Can you master a song online without plugins?
Yes. An online tape mastering tool lets you upload your final mix, add analog-style glue and warmth on the mix bus, and check integrated LUFS and true-peak — then export a print-ready WAV. There’s nothing to install, and the processing runs on a server, so you don’t need a powerful computer or a plugin license.
Step 1 — Start with a clean, headroom-friendly mix
Master a mix that peaks around −6 to −3 dBFS with no limiter on the bus. Mastering can’t fix a distorted or over-compressed mix, so bounce a clean WAV (24-bit or 32-bit float is ideal) and leave headroom for the tape stage and final loudness adjustment.
Step 2 — Add tape for glue, warmth, and smoother highs
Run the mix bus through the tape engine and start subtle. Tape adds harmonic warmth, gentle compression for glue, and a natural high-frequency roll-off that tames brittle, fatiguing highs. Use a level-matched A/B so you’re judging tone, not a loudness jump.
- Tape speed sets the low-end character and head bump.
- Drive controls how much harmonic warmth and density you add.
- Compression glues the elements together — keep it gentle for mastering.
Step 3 — Hit the right loudness target
Use the LUFS meter to match where your music lives. Streaming platforms normalize around −14 LUFS integrated, so mastering near −14 to −9 LUFS suits most modern releases, while club or competitive genres go louder. Always watch true-peak and keep it at −1 dBTP or lower to avoid intersample clipping.
Step 4 — Export the right format
Export a 24-bit or 32-bit float WAV with TPDF dither for delivery, and keep a 32-bit float copy if you’ll keep working on it. Avoid mastering straight to MP3 — master to WAV, then create MP3s from that file if you need them.
Common online mastering mistakes to avoid
- Mastering too loud — chasing volume crushes dynamics and adds distortion.
- No headroom in the mix — leave room before the master stage.
- Trusting volume, not tone — always A/B at matched level.
- Ignoring true-peak — intersample peaks clip on lossy playback.
How much does online mastering cost?
With Tape DSP you get free starter credits to master real audio at no cost, then pay-as-you-go credits based on length — no subscription, and credits never expire.
Is tape enough to master a whole song?
For many mixes, tape tone plus careful loudness and true-peak control is a complete, musical master. If a mix needs heavy corrective EQ or multiband work, fix it in the mix first, then master.
