How to Master a Song on a Chromebook (No Software to Install)
Published · by Loopin
On a Chromebook, the fastest route to a finished master is an online masterer: export a clean mix, drop it in, A/B it, download the WAV. Here's the 15-minute version, plus the checks that stop the laptop speakers lying to you.
Skip the install rabbit hole
Most mastering plugins and desktop DAWs ship as Windows or macOS installers, and ChromeOS doesn't run those. Many Chromebooks can switch on a Linux environment, and a few audio tools run there, but on a low-RAM machine you'll spend an evening on drivers and dropouts before you hear a single master.
Skip it. You don't need a DAW to master a finished mix. You need a clean stereo file, a masterer that doesn't need installing, and ten minutes of careful listening. For the full no-DAW workflow, see how to master a song without a DAW.
Get the mix file right before anything else
Wherever you mixed — BandLab, a web DAW, a friend's laptop — export a WAV if you can, at the project's sample rate, with the loudest moment peaking around −6 to −3 dBFS. Take any limiter or loudness maximiser off the master bus. A mix that's already slammed leaves the masterer nothing to work with.
If all you have is an MP3, use it, but use the highest-quality one. Don't convert an MP3 to WAV and expect it to sound better — it won't, it's just bigger. Name the file with the song and version ("song-mix-v3.wav") so you can tell masters apart later.
Master it online and pick the feel
Open Loopin's free online mastering, drop the file in, and start with the feel closest to the genre: Punchy for rap and pop, Warm for acoustic, soul and R&B, Crisp for dull or dark mixes, Club for dance, Lo-fi for dusty beats. There's no account to make and nothing to install, which is the whole point on a Chromebook.
Use the Original-vs-Mastered switch. It's loudness-matched, so you're hearing tone, not volume. If the master only sounds better because it's louder, try a different feel. Two or three tries is normal; more than five usually means the problem is in the mix.
Don't trust the laptop speakers alone
Chromebook speakers roll off most of the bass below roughly 150–200 Hz, so a kick that sounds polite on the laptop can be booming on a car system. Check every master on three things: the laptop speakers, a pair of wired or wireless headphones, and your phone speaker.
Listen for a different problem on each. Headphones: is the low end controlled, or is the bass swamping the kick? Phone: can you still hear the vocal and the hook? Laptop: does the loudest chorus crackle? More ways to do this are in how to test a master on different speakers.
Download the WAV and keep the original
When one version wins on all three, download it. Loopin exports a 16-bit WAV at about −14 LUFS with a −1 dBTP ceiling, which is what distributors accept and where Spotify and YouTube normalise to. Punchy lands closer to −11 LUFS and Club near −10 if the genre wants that density.
Save the master next to the mix in Google Drive or a USB stick, named "song-master-punchy.wav" or similar. ChromeOS clears the Downloads folder on some setups when storage runs low, so don't leave your only copy there.
Fix these in the mix, not the master
If the vocal is too quiet, the hi-hats are piercing, or the bass disappears on the phone, go back to the mix. Mastering nudges the whole track; it can't move one instrument. Change the mix, re-export, and master the new version free — unlimited re-runs cost nothing.
And skip the urge to stack masters. Running a mastered file through again just adds another round of limiting. Always master from the mix.
Frequently asked questions
Can you master a song on a Chromebook?
Yes. Use a free online masterer: no DAW or plugin needed. Export a WAV mix peaking around -6 dBFS, master it online, A/B it, and download the finished WAV.
Can I install mastering plugins on a Chromebook?
Usually not. Most plugins and DAWs ship as Windows or macOS installers. Some Chromebooks support a Linux environment, but setup is fiddly and low-RAM models struggle.
What's the best free mastering for Chromebook?
An online masterer with no install. Loopin Mastering is free, unlimited and needs no sign-up, with eight feels and a loudness-matched before/after switch.
How loud should my master be?
About -14 LUFS with a -1 dBTP true-peak ceiling suits Spotify and YouTube. Rap and dance can go to around -11 or -10 LUFS if the genre calls for it.
Why does my master sound different on my Chromebook speakers?
Laptop speakers lose most bass below about 150 to 200 Hz. Always check on headphones and a phone as well before you release.
Should I master an MP3 or a WAV?
Master a WAV if you have one. An MP3 works, but converting an MP3 to WAV first won't add any quality back.
