SoundBoost.ai (formerly Diktatorial)
AI music mastering with text prompts, guide the AI with words and hear the magic. Includes a free stem splitter as well.
On SoundBoost.ai (formerly Diktatorial)
SoundBoost.ai turns a simple text prompt into a polished, streaming-ready master in under a minute. Upload a WAV or MP3, describe the sound you want—e.g. “warm and wide like Billie Eilish” or “festival energy”—and the AI engine picks an engineer persona (Sophia, Marcus, etc.), builds a genre-aware signal chain, and renders a final master optimized for Spotify, Apple Music, YouTube and more. The same subscription unlocks mobile apps for iOS and Android, a free stem splitter and vocal remover, and a visual creator for album art and Spotify Canvas videos.
SoundBoost is the fastest way to turn a text prompt into a streaming-ready master, and it’s genuinely useful for musicians who want AI assist without losing creative control. The six engineer personas and reference-mastering feature set it apart from generic AI mastering tools, and the free LUFS meter and vocal remover add real value. The catch: it still needs a clean, headroom-rich mix to shine, and the free tier is too limited for serious use.

Frequently asked questions
What’s mastering anyway?
Mastering is the final polish that makes a mix sound its best across all playback systems. It addresses loudness, tonal balance, stereo width and translation, ensuring your track sounds professional on Spotify, headphones, car stereos, etc.
What makes SoundBoost’s AI mastering different?
SoundBoost builds a genre-aware signal chain from hundreds of modeled processors and lets you pick an AI engineer persona (e.g., Sophia for smoothness or Marcus for high-energy). You can also guide the master with natural-language prompts and compare versions instantly.
How fast can I go from mix to a release-ready master?
Upload a WAV, choose an engineer or prompt, and the engine renders a streaming-ready master in about one minute. You can then export to WAV/MP3/FLAC/OGG/AAC/M4A at 16/24/32-bit and 44.1 or 48 kHz.
Can I master on my phone or tablet?
Yes. The iOS and Android apps mirror the desktop suite, so you can upload tracks, tweak prompts and publish from your phone without losing quality.
Do I still get creative control or is everything locked to AI decisions?
You’re always in control: toggle intensity, analog warmth, saturation and width in real time, switch engineers, use A/B comparison, and finalize only when you’re happy. Reference mastering lets you chase a target track’s loudness and tone.
How do I make sure my master translates everywhere?
Use the built-in loudness penalty analyzer and device simulation to preview how Spotify, YouTube, Apple Music, cars, laptops and phones will treat your mix before you release.
Is my audio private and secure?
SoundBoost does not train its models on your masters or share them with third parties. Client-side tools like the LUFS meter and loudness penalty analyzer run entirely in your browser.
