FreeSoundBoost.ai: Your multilingual AI mastering engineer—preserve the emotion, add the polish.
About DIKTATORIAL
SoundBoost.ai (formerly Diktatorial) is an AI-powered online mastering suite designed to act as a virtual mastering engineer for musicians and producers. The platform allows users to upload audio tracks and guide the mastering process using natural-language prompts, such as describing a desired sound or referencing a specific artist. It also supports reference mastering by pasting a Spotify link to match loudness, width, and tone. Beyond mastering, the suite includes a stem splitter and vocal remover for separating vocals, drums, bass, and instruments, as well as a visual creator tool. The service is accessible via desktop browser and mobile apps for iOS and Android, with project syncing across devices.
The AI mastering engine processes the full signal chain, including revisions and final polish, and offers multiple AI mastering engineer personas (e.g., Sophia for smoothness, Marcus for a more aggressive sound) that users can switch between. The platform emphasizes preserving the emotion and detail of the original recording while adding analog warmth and saturation. It also provides free, privacy-respecting loudness and playback simulation tools. SoundBoost.ai is trusted by over 410,000 masterings, according to the website, and offers a free preview without requiring signup.
As a comprehensive suite, SoundBoost.ai covers audio input and output for mastering, stem splitting, and vocal removal. The visual creator tool suggests additional output types beyond audio. The platform appears to be a SaaS product with a free tier, though exact pricing details for paid plans should be verified on the website.
