Mastering for SoundCloud vs Spotify: What Is Actually Different
Most producers master one file and upload it everywhere, then wonder why a beat that sounds huge on SoundCloud feels flat on Spotify. The platforms don't process audio the same way, and if you don't account for that, you're leaving loudness and clarity on the table before a single listener hits play.
Loudness normalization is the real difference
Spotify normalizes to around -14 LUFS integrated. SoundCloud's normalization is less consistent and, depending on the upload path, sometimes doesn't apply at all. That means a track slammed to -6 LUFS for maximum loudness gets turned down hard on Spotify, but can hit a listener at full, unducked volume on SoundCloud. If you master everything to one aggressive loudness target assuming "louder wins," you're only winning on one platform and getting flattened on the other.
The fix isn't complicated: master toward -14 to -12 LUFS integrated as your baseline. On Spotify you'll sound comparable to everything else in the feed instead of getting turned down and losing punch. On SoundCloud you'll have headroom that keeps the low end from folding in on itself when it isn't normalized down.
True peak matters more than you think
Streaming platforms transcode to lossy formats, and inter-sample peaks that were fine in your WAV can clip after encoding. Leave true peak headroom around -1 dBTP on your master. This matters more for SoundCloud, where you're more likely to see the file played back closer to its original state, but it's cheap insurance either way. A limiter set to slam right up to 0 dBTP is asking for distortion you won't hear until it's already live.
Low end behaves differently per platform
808s and sub-heavy trap productions are the clearest place this shows up. On SoundCloud, without consistent normalization, an unchecked low end can dominate a mix and eat headroom you needed for clarity up top. On Spotify's normalized playback, that same low end gets pulled down along with everything else, so a beat that felt bass-forward on SoundCloud can feel thinner on Spotify. Check your master on both a phone speaker and real monitors before you call it done - the low end lies to you on laptop speakers either way.
What I actually do
Working out of my studio in Knoxville, I master to one solid reference point - around -13 LUFS integrated, -1 dBTP true peak - and let that be the version that goes everywhere. I stopped chasing platform-specific loudness wars a while back because the tradeoffs cancel out. A track that's honestly mixed and reasonably loud holds up better across formats than one gamed for a single platform's algorithm.
The takeaway
Don't master for loudness. Master for balance, keep your true peak in check, and trust that a track with real clarity in the low end and top end will translate whether SoundCloud normalizes it or not.
