Echoteka vs SunoMaster: two ways to master a Suno song

October 28, 2026 · All posts

SunoMaster and Echoteka both exist for people who make songs in Suno, and both let you master a track for free. They work in very different ways. SunoMaster runs entirely in your browser, so your audio never leaves your computer. Echoteka uploads the file and masters it on a server, with a cleanup step for AI artifacts and a measured before/after report. This page puts the two side by side, with every SunoMaster fact taken from SunoMaster's own pages on 28 October 2026.

Side by side

Prices change. Check both sites before you buy.

Where SunoMaster is the better choice

• You do not want to upload your song anywhere. SunoMaster's FAQ says processing happens "100% locally in your browser using Web Audio API and FFmpeg.wasm", and that only license keys are checked with its server. Echoteka has to receive the file to master it.
• You want unlimited free masters. Simple mode has no daily cap. Echoteka's free tier is one full master a day; more masters use credits.
• You master a lot of tracks. A €28.99 lifetime license for V3 Advanced is the price of about 22 Echoteka masters at our lowest per-track price (€1.30 in the 30-track pack). Past that point, SunoMaster costs less.
• You want hands-on controls. The advanced modes give you an EQ, multiband compression, genre presets and a preset marketplace. Echoteka gives you profiles and targets, not a full console.
• Speed. SunoMaster's FAQ puts a three-minute song at five to ten seconds, because nothing is uploaded or downloaded.

Where Echoteka fits better

• You want the numbers, not just a file. Every Echoteka master comes with a before/after report: integrated loudness, true peak, loudness range and stereo. You can check the result without trusting our ears or yours.
• Your track has AI artifacts. Echoteka cleans metallic ringing and watery highs before mastering, as its own step. See what artifact cleanup changes.
• You need 24-bit or FLAC. SunoMaster's FAQ lists WAV at 44.1 kHz 16-bit. Echoteka exports 24-bit WAV, FLAC or MP3 320.
• You want a streaming target, not a genre guess. SunoMaster aims louder for energetic genres: −11 to −12 LUFS for EDM and hip-hop, according to its FAQ. Echoteka masters to the platform you choose and keeps true peak under −1.0 dBTP. On Spotify, a louder master is turned down to the same level anyway.
• You pay per track, not per month. There is no subscription, and if a master fails, its credit returns to your balance automatically.

Do Suno exports sit at −16 LUFS?

SunoMaster's FAQ says Suno generates tracks "at approximately −16 LUFS". Our own measurements say something different. In 248 Suno exports that people uploaded to us for mastering between July and October 2026, the median was −14.3 LUFS, and only 8% were quieter than −16 LUFS. The sample comes from people who chose to master their track, so it is not a random sample of everything made in Suno. The method is in the Suno loudness report.

This matters for both tools. If your export already sits near −14 LUFS, a master should not push it much louder. A Suno export already at −13.6 LUFS shows what mastering changed on one such track, including the one number that got worse.

Test both on the same song

1. Measure your Suno export in the free LUFS checker.
2. Master it in SunoMaster's Simple mode and in Echoteka's free daily master.
3. Measure both results the same way.
4. Match their loudness before you listen. The louder file always sounds better for the first few seconds.

How to choose an AI mastering service has a longer version of this test.

FAQ

Is SunoMaster free? Simple mode is free, with unlimited masters and no watermark, according to SunoMaster's FAQ. V3 Advanced costs €9.99 a month or €28.99 for lifetime access.

Is SunoMaster part of Suno? No. Its site says it is not affiliated with or endorsed by Suno. Echoteka is not affiliated with Suno either.

Is Echoteka free? 1 full master a day is free to download as MP3 320, with no account; WAV after a free sign-up. Signing up adds 3 bonus masters. After that, masters use credits from €1.30 to €3 each, depending on the pack.

Which one is private? SunoMaster never receives your audio. Echoteka does, because it masters on its servers; the privacy policy explains what is stored and for how long.
