SoundCloud Mastering: Master Your Track Before You Upload

In short

For SoundCloud mastering, start from your finished mix, not a loud bounce. Upload it here, pick a sound profile, adjust Intensity, EQ and Input Gain, then compare Original and Mastered and read the report. Members can download WAV or MP3, and SoundCloud accepts both. Previewing is free and needs no sign-in.

What this page covers

SoundCloud mastering here means one narrow job: take a finished track of your own and get it ready to upload. The tool has no SoundCloud connection, so it never reads your account or posts anything. You master the song, download the result, and upload that file yourself.

The mastering uses automated presets, not a trained AI model. They work on the whole song: tone with EQ, dynamics with compression, and level with a limiter. Fixing a single instrument is a different job, and it belongs in the mix itself.

SoundCloud mastering starts with the file you export

What you bring decides most of what you get back, so check the export first.

• Export the whole song as one file. The tool takes a completed mono or stereo mix, not separate stems.
• Prefer WAV or AIFF. The upload box also accepts FLAC and MP3. If an MP3 is all you have, it works, but converting an MP3 to WAV will not bring back detail the MP3 already threw away.
• Leave room at the top. A bounce that already touches full scale leaves little to work with. The report adds a note when the highest sample of your upload is at or very near full scale: "The input is near full scale. This tool cannot restore information lost to clipping."
• Don't make the export loud first. In standard mode the engine moves your track to an internal working level before it processes anything, so a modest-level export is fine.
• Stay inside the limits. Files can be up to 200 MB and 10 minutes. Silent files, or files whose level is too low, are rejected.

Files up to 48 kHz keep their sample rate. Anything higher is resampled to 48 kHz before processing.

Which file goes where

The SoundCloud row comes from its Upload Requirements help page, read on 2026-10-28. It lists WAV, FLAC, AIFF, ALAC and MP3 among the formats it accepts and recommends uploading lossless formats such as WAV, FLAC, AIFF or ALAC.

Between the two WAV options, 24-bit keeps the master as it was rendered. The 16-bit export adds dither when it reduces the bit depth. Choose the MP3 only when a small file matters more than keeping everything.

How to do SoundCloud mastering in 3 steps

Choosing a profile for SoundCloud mastering

The eight profiles are starting points, not rules. Audition a few on your own track, in quiet and busy sections alike.

• Universal: balanced tone with gentle compression, a safe place to begin.
• Natural: gentle compression for a lighter touch, for mixes that already feel finished.
• Clarity: brighter highs with less low-mid weight, for a mix that sounds dull or thick in the low mids.
• Punch: added low-end weight and punch, for tracks that feel soft.
• Tape: warm tone with gentle saturation.
• Fire: added weight, brighter highs and stronger compression.
• Cinematic: fuller lows with added saturation.
• Spatial: wider stereo with a touch of reverb.

Set Intensity after the profile. Higher values push harder.

What the report tells you before you upload

The report under the player keeps you honest, because it measures the file instead of describing it. The table shows Loudness (LUFS), Estimated true peak (dBTP) and Sample rate for Original and Mastered. Read it like this:

• Compare, don't chase. The two columns show what mastering did to your song. They are not scores against any service.
• Mastered figures are for the base render. They come from the profile at Intensity 50 with flat EQ, plus your Input Gain, which triggers a fresh render. Intensity and EQ moves are heard live but not measured again, so the table can drift from what you hear.
• True peak is an estimate. It comes from four-times oversampling and is not a certified meter.
• Read the notes line. It warns when the input is near full scale or has a low crest factor, which means dynamic compression was reduced.

This page gives no loudness number to aim for. The tool has no loudness-target control, and the report's notes describe its loudness targets as "experimental starting points, not platform delivery standards". For a longer walk through the two measurements, see what the loudness and peak figures mean.

What to upload after SoundCloud mastering

• Listen to the download, not just the preview. The download is rendered at your current settings, so play it from start to finish before you upload it.
• Keep your unmastered export. You can start again from the source if you change your mind.
• Listen on more than one system. Play the download on headphones and a phone speaker before you upload it.
• Quiet is not a reason to push harder. If the song is only quiet, your options for a quiet track are worth reading before you raise Intensity.

SoundCloud situations and how to handle them

A demo bounced in a hurry

Re-export the session as WAV if you can. A fresh export beats mastering an MP3 of an MP3.

A mix that already clips

Mastering will not rebuild flattened peaks. Go back to the session, pull the level down and export again. The report's near-full-scale note is your cue.

A long mix or full set

The tool stops at 10 minutes and 200 MB, so a longer file is rejected. Check the length before you spend time on settings.

A song you only want to hear

Previewing is free, so audition profiles first and download only the version you would upload.

The honest limits

• It never touches your SoundCloud account. You download and upload the file yourself.
• There is no loudness target. You cannot enter a LUFS figure, and the limiter's ceiling is fixed at −1.5 dB with no threshold or ratio control.
• It cannot repair the mix. A vocal that is too quiet or two parts masking each other should be fixed first, as fix it in the mix first explains.
• Results depend on the source. Presets shape tone and dynamics. They cannot restore missing notes or remove severe distortion.
• The report is a snapshot. The Mastered figures describe the base render, and the true peak is estimated.
• SoundCloud mastering has size limits here. Songs can be up to 10 minutes and 200 MB, and downloads need the membership.
• Unsaved audio is lost when the page closes. Keep the page open until cloud saving finishes, or download the master.
