How to master a song for SoundCloud

Start with the right source

Mastering prepares your finished mix for release. It cannot reliably fix an overloaded recording or buried vocal. Export your mix without clipping. Keep a separate copy before changing anything. If your vocal disappears behind the beat, fix that balance in the mix first.

SoundCloud recommends lossless WAV, FLAC, AIFF or ALAC uploads. Its guidance specifies stereo files at 16-bit, 44.1 kHz or higher. Keep your project's native sample rate when possible. Converting an MP3 into WAV does not restore missing detail. Check the official upload requirements before your release.

Use loudness targets as guidance

LUFS measures perceived loudness. Integrated LUFS averages that measurement across the track. True peak estimates peaks between digital samples. Its unit is dBTP. These measurements answer different questions: overall level and peak headroom.

SoundCloud's mastering guidance recommends −14 integrated LUFS and peaks below −1 dBTP. For louder masters, it recommends peaks below −2 dBTP. These are recommendations, not mandatory upload targets or rejection thresholds. Do not crush a good mix to reach a number.

The upload page describes sample-peak headroom in dBFS. The mastering page discusses true peak in dBTP. These are not interchangeable measurements. Follow the true-peak guidance when checking your final master.

Build the master in small moves

1. Listen through your whole mix. Mark harsh sections, weak vocals and bass that swallows the kick.
2. Use gentle tonal adjustments. Return to the mix if a problem needs a large correction.
3. Check stereo width in mono. Keep the vocal and low end stable rather than chasing maximum width.
4. Limit peaks near the end of the chain. Begin conservatively and keep space below the recommended ceiling.
5. Raise the level gradually. Back off when drums flatten, bass pumps or consonants become brittle.
6. Export a WAV and measure that file. Check both integrated loudness and true peak.

Use a level-matched reference track to compare tone and punch. Match listening levels yourself; louder playback can disguise worse processing. BRIDGE ONE offers dry/wet A/B comparison, not a confirmed automatic loudness-matching feature.

Listen after SoundCloud processes it

SoundCloud transcodes uploads for playback. Lossy encoding can change peak levels and reveal distortion. Headroom reduces that risk; it does not guarantee every encoded version stays clean. Upload privately first, then audition the loudest chorus, bass hits and vocal sibilance. Compare on headphones and a small speaker at sensible levels.

If the uploaded version crackles, reduce limiting and leave more headroom before exporting again. Also check whether the source recording already contains distortion. Our free mastering distortion checklist helps separate those problems.
