How to Master for SoundCloud

The short version of how to master for SoundCloud: aim for about -14 LUFS integrated with true peak at or below -1 dBTP, then confirm both numbers in a free volume normalizer before you upload. If your track ends up louder than -14 LUFS, tighten that ceiling to -2 dBTP for extra transcode headroom. Those numbers are the whole target — the rest of this guide is about hitting them cleanly, and not squashing your mix to chase a loudness SoundCloud is going to level out anyway.

This is a pre-upload check on a file you already have — a single, a producer bounce, or a DJ mix. It takes a couple of minutes, runs in your browser, and your audio never leaves your device. Whether you're uploading a track or a two-hour set, you're working on a lossless file already on your machine, so there's no link to paste and nothing to rip.

The loudness target for SoundCloud

SoundCloud plays uploads through loudness normalization aimed at about -14 LUFS integrated. Here's the part that sets it apart from YouTube and Spotify: SoundCloud's guidance says it adjusts in both directions. It turns loud tracks down toward -14 LUFS, and it turns quiet tracks up toward it. On the major streaming services, normalization is effectively down-only — a quiet upload just plays quietly. SoundCloud's stated behavior is to meet you at -14 either way.

In practice, how strictly that plays out has been reported as less consistent across SoundCloud's players and apps than on the majors, so treat -14 LUFS as the working target rather than a guarantee that every listener hears an identical level. It's still the number to master to. If integrated loudness is new to you, what LUFS you should master to lays out the per-service targets in one place, and integrated LUFS versus short-term and momentary explains why the integrated reading — one number for the whole track — is the one platforms normalize against. For the mechanics of why any of this happens, how streaming loudness normalization works covers the full picture.

Why true peak matters on SoundCloud

The second number is a ceiling, not a target. SoundCloud transcodes every upload to a lossy streaming format — it's migrating to AAC over HLS at around 160 kbps, with a 96 kbps fallback, while the older MP3 128 kbps and Opus 64 kbps transcodings are being retired. Lossy encoding can add inter-sample peaks that weren't in your original file, nudging a master that read -0.1 dBTP into audible clipping once it's streamed. True peak (dBTP) measures those inter-sample peaks that a normal sample-peak meter misses; what true peak (dBTP) is explains why it differs from the peak your DAW usually shows.

SoundCloud's own guidance on the ceiling is conditional, and it's worth following exactly:

• If your track is quieter than -14 LUFS, keep true peak below -1 dBTP.
• If your track is louder than -14 LUFS, keep true peak below -2 dBTP for extra transcode headroom.

The logic is that a hotter master leaves the encoder less room, so you compensate with a lower ceiling. When in doubt, -2 dBTP is the safer choice — the decibel you "lose" is inaudible after normalization anyway.

What you'll need

• Your audio as a lossless file you already have — WAV, FLAC, or AIFF — not a pre-compressed MP3. Lossless in means SoundCloud transcodes from full quality.
• A modern browser. No account, no install, no upload.
• About two minutes to measure, adjust, and re-measure.

Steps

Mastering for SoundCloud is two jobs: shape tone and dynamics, then land the loudness and peak targets. Do them in that order.

1. Master tone and dynamics first (optional, for raw mixes). If your file is a raw mix rather than a finished master, run it through the audio mastering tool to glue the mix, balance tone, and apply gentle limiting. That's where a real master gets its polish — a normalizer alone can't do it. If you already have a master you're happy with, or you're uploading a finished DJ mix, skip to step 2.

2. Open the volume normalizer and drop in your file. The free volume normalizer reads your file and shows a Before panel with its measured integrated LUFS and true peak (dBTP). Note both numbers — that's your starting point.

3. Set the target to -14 LUFS. In Loudness (LUFS) mode, choose a -14 LUFS preset. There's no dedicated SoundCloud button, but the Spotify and YouTube presets are both -14 LUFS — click either one. (The Apple Music preset, for comparison, is -16.)

4. Keep Prevent clipping on. Leave the Prevent clipping (cap true peak at -1 dBTP) checkbox ticked — it holds the ceiling while the tool works toward the loudness target. If the Before panel shows your master is already louder than -14 LUFS, switch to Peak mode and set the dBTP slider to -2 instead, matching SoundCloud's conditional headroom rule.

5. Preview and read the After panel. Click Preview after-LUFS. The After panel shows the integrated LUFS and true peak your exported file will have, plus the exact gain offset applied — so you can see whether the tool turned your track up or down. Confirm it lands near -14 LUFS with peak at or below your chosen ceiling.

6. Export lossless. Pick a format in the export selector — WAV (lossless, the safe default) is ideal — and click Export WAV. MP3, FLAC, M4A, and Opus are also available, but for SoundCloud you want to upload the lossless file so it transcodes from full quality. Upload that file; SoundCloud handles normalization from there.

Should you master louder for SoundCloud?

No — and this is the trap. Because SoundCloud pulls everything toward -14 LUFS, mastering hot to "sound competitive" buys you nothing. A -8 LUFS master gets turned back down toward -14 on playback, so you've traded away your dynamic range for a loudness the platform discards, and the extra limiting only stacks more distortion on top of the AAC transcode. That's the loudness war losing its own point. Master to sound good at around -14 LUFS, let it breathe, and let normalization handle the level.

One caveat about the normalizer itself: it applies a single gain offset and holds the true-peak ceiling — it is not a multiband limiter. If a mix is quiet and undynamic, normalizing it toward -14 will hit the -1 dBTP ceiling and stop rather than crush peaks to force more loudness. That's your cue to do the tonal work in the audio mastering tool first. If mastering itself is unfamiliar territory, what audio mastering is is a good place to start.

Troubleshooting

My track is quieter after normalizing. That's correct if your master was louder than -14 LUFS — the tool turned it down to match SoundCloud's target, which is exactly what the platform would do on playback. You lose nothing: listeners hear the same loudness either way, and your peaks are now safe going into the transcode.

True peak is still over the ceiling after I export. Lossy encoding can add inter-sample peaks, so a file that read exactly -1.0 dBTP can nudge over once SoundCloud transcodes it to AAC. Give yourself margin: re-run the file in Peak mode with the slider at -2 dBTP, especially if your master sits above -14 LUFS. Uploading a lossless WAV rather than a pre-compressed MP3 also avoids stacking your own export encoding on top of SoundCloud's.

My upload sounds distorted or harsh after processing. That's usually a master that was already too hot meeting SoundCloud's lossy transcode. Over-limited, brick-walled audio has the least headroom for the encoder, so inter-sample peaks and codec artifacts show up first there. Back the loudness off toward -14 LUFS, leave -2 dBTP of true-peak headroom, and re-upload — a cleaner, more dynamic master transcodes far better than a loud one.

Frequently asked questions

What LUFS should I master to for SoundCloud? Aim for about -14 LUFS integrated. SoundCloud normalizes playback toward that level, so -14 LUFS is the sweet spot: loud enough to sound full, not so loud that the platform pulls it back down and you've lost dynamic range for nothing. Keep true peak at or below -1 dBTP, or -2 dBTP if your track is louder than -14 LUFS.

Does SoundCloud turn quiet tracks up? According to SoundCloud's own guidance, yes — its normalization is described as adjusting in both directions, turning loud tracks down and quiet tracks up toward -14 LUFS. That's a key difference from Spotify and YouTube, where normalization is effectively down-only. How consistently it plays out has been reported to vary across SoundCloud's players, so -14 LUFS is still the target to master to rather than a level you can assume every listener hears identically.

Do I need software to master for SoundCloud, or can I do it free in a browser? You can do it free in a browser. A volume normalizer measures and adjusts loudness and true peak with no account or install, and your audio never leaves your device. For tonal and dynamic mastering on a raw mix, a browser mastering tool handles that step too — the same targets, -14 LUFS and -1 dBTP, apply either way.

Should I upload a WAV or an MP3 to SoundCloud? Upload a lossless file — WAV, FLAC, or AIFF — not a pre-compressed MP3. SoundCloud transcodes every upload to a lossy streaming format (AAC over HLS at around 160 kbps), so starting from lossless gives the encoder the best possible source. Uploading an MP3 means SoundCloud transcodes a file that's already lost quality, stacking compression artifacts.

Is mastering for SoundCloud different from mastering for Spotify? The loudness target is the same — both aim for about -14 LUFS integrated with true-peak headroom. The practical differences are that SoundCloud says it turns quiet tracks up as well as loud ones down, and it applies a conditional peak ceiling: -1 dBTP if you're quieter than -14 LUFS, -2 dBTP if you're louder. A master made for Spotify will work on SoundCloud; just tighten the ceiling to -2 dBTP if your track is on the hot side.
