Echoteka 1.2: hear the difference, then master from anywhere

October 10, 2026 · All posts

A week after 1.1 gave everyone a free master every day, Echoteka 1.2 is about two things: letting you hear what mastering does before you trust it with your song, and letting you master from wherever you already work — your browser, your AI assistant or Telegram.

Hear it before you upload

Every mastering site says "release-ready". We would rather show you. The home page and the Suno mastering page now have a before/after player on a real Suno song.

• Loudness-matched. Both versions play at the same loudness, so you hear the difference in tone and clarity, not just "louder sounds better".
• Same moment. Switching between before and after keeps your place in the song, so you compare the same bar.

The LUFS checker also has a "Try a 20-second sample" button: see loudness, true peak and loudness range on a real track without uploading anything of your own.

Master from your AI assistant

If you work in Claude Code, Claude Desktop, Cursor or OpenAI Codex, you can now master without leaving it. Add our MCP server — https://echoteka.ai/mcp — and ask your assistant to:

• analyze a track's loudness and dynamics,
• clean AI artifacts,
• preview styles,
• master a single track or a whole album from a link.

The free daily master works there too. Sign in from your assistant (OAuth) and it can use your account's bonus masters. There are no payment tools: the assistant cannot pay for anything.

Restore old recordings

The new audio restoration page has ready-made sets for cassette, vinyl, phone and interview recordings — tape hiss, hum, clicks and room echo cleaned up before the master. Restoration also got more honest:

• Hum removal only when there is hum. A clean recording no longer loses a bit of its low end to a filter it did not need.
• Zero means off. Set a strength slider to zero and that module really stops working.
• See what was fixed. The report counts how many clicks were found and how many were repaired.

Clean and master in one run

For Suno tracks you no longer need two passes. Turn on "Also clean AI artifacts" and cleanup runs as part of the master — free, at no extra cost. If you only want the cleanup, it now downloads as MP3 or FLAC as well as WAV.

One honest note: cleanup shifts pitch by 7 cents. It is hard to hear, but we would rather tell you. Cleanup takes generator traces out of the sound; it does not hide that a song was made with AI. Curious what it does in numbers? We measured it on 2,230 tracks.

Loudness follows your platform

Pick Spotify, Apple Music, a club or another platform, and that choice sets the loudness. The genre and the AI advice now shape the sound — tone, density, character — not the level. Speech presets and "Already loud" keep their own targets, because their loudness is the point.

Cleaner bass, safer stereo

• No more dips on low 808 notes. The lowest-frequency filter was cutting twice as much as intended. Fixed — the low end stays even.
• Wide tracks stay as they are. If a mix is already wide, we no longer widen it, so it holds together when played in mono on a phone or a small speaker.

More ways in

• New upload formats: AAC, AIFF and WebM — including voice recorded right in the browser.
• An AI consultant on the site and in the Telegram bot @EchotekaAIBot. Ask about loudness or your mix, and get your masters delivered straight to Telegram.
• Invite a friend: you both get +3 masters.

New guides

• Apple Music loudness — what −16 LUFS means for your release.
• What AI artifact cleanup actually changes: 2,230 tracks measured
• Audiomack, Boomplay and JioSaavn loudness — what is published and what is not.
• A Suno export already at −13.6 LUFS — what mastering changed, and what it didn't.

Try it

Listen to the before/after player, then master a track free — one full master every day, no account needed. Every change is listed in the changelog.
