# Echoteka

> Online mastering for AI-generated music (Suno and other generators) and home recordings. Upload a track, get a release-ready master and a before/after report that measures loudness (LUFS), true peak, dynamics and stereo, with a plain verdict. Operated by ECHOTEKA Ltd. (Bulgaria, EU). English only.

Current version: Echoteka 1.2 (October 10, 2026). Release notes: https://echoteka.ai/changelog
- 1.2: before/after player on a real Suno song (home page and /suno-mastering, loudness-matched) and a 20-second sample in the LUFS checker; MCP server for Claude Code, Claude Desktop, Cursor and OpenAI Codex with sign-in from the assistant (OAuth) to use account bonus masters, no payment tools; audio restoration page (cassette, vinyl, phone, interview), hum removal only when hum is found, zero strength = off, click counts in the report; AI artifact cleanup and mastering in one run (free switch), cleanup download as MP3/FLAC, pitch shifts by 7 cents; loudness set by the chosen platform, genre and advice change the sound only (speech presets and "Already loud" keep their own targets); AAC, AIFF and WebM uploads; AI consultant on the site and in the Telegram bot @EchotekaAIBot (masters delivered to Telegram); invite a friend: +3 masters each; new guides on Apple Music loudness, AI artifact cleanup (2,230 tracks), Audiomack/Boomplay/JioSaavn loudness and a Suno export already at −13.6 LUFS; fixed bass dips on low 808 notes, already-wide tracks no longer widened.

- 1.0 (September 29, 2026): public launch.

## What it does
- Masters a track to streaming loudness (Spotify, Apple Music, YouTube) with a true-peak ceiling.
- Cleans typical AI-generation artifacts: harsh highs, smeared transients, noisy tails.
- Shows a before/after report for every master, so the result can be checked, not just heard.
- Basic track analysis is free and needs no account. The AI track check costs 1 credit and needs an account.

## Pricing
- Free: basic analysis; 1 full master every day with no account needed (one per device or network per day, days counted in UTC); signing up adds 3 bonus masters. Details: https://echoteka.ai/free-ai-mastering
- Payments are processed by Paddle (merchant of record).

## MCP server
- Remote Model Context Protocol server: https://echoteka.ai/mcp (streamable HTTP, no key or account needed). Lets an AI assistant (Claude Code, Claude Desktop, Cursor, OpenAI Codex) analyze loudness, clean AI artifacts, preview presets and master tracks or albums from a public audio link. Free analysis and the free daily master apply; the server has no payment tool, so extra masters need credits, and an assistant cannot pay for them. Connect: `claude mcp add --transport http echoteka https://echoteka.ai/mcp`
