About
SoundBoost is a comprehensive AI-powered music production suite built for musicians who want professional results without complex gear or expensive studio time. At its core is an AI mastering engine (currently on v3.5) that accepts natural-language prompts — describe your desired sound like "Wide stereo field" or reference a Spotify track, and the AI handles the full signal chain, EQ, loudness matching, and final polish automatically. Beyond mastering, SoundBoost offers a Stem Splitter & Vocal Remover that separates audio into individual components (vocals, drums, bass, etc.) with controls for pitch, tone, BPM, and mix renders. A Visual Creator tool generates cover art, artist photos, and promotional visuals designed to complement your music's aesthetic. The platform supports multiple AI mastering engineer personas — for instance, Sophia optimizes for smoothness and clarity, while Marcus is tuned for harder-hitting electronic styles. A Guided Mode streamlines the revision flow for quick iteration, while a Detailed Mode offers surgical control. Free tools like a Loudness Penalty checker, LUFS Meter, Audio Converter, and Metadata Editor are also available without a subscription. One paid subscription covers the full experience across web, iOS, and Android, making it accessible for on-the-go music production. Trusted by over 290,000 masterings, SoundBoost is built for independent artists, producers, and content creators who need fast, high-quality audio mastering.
Key Features
- Prompt-Guided AI Mastering: Describe your desired sound in plain language (e.g., 'warm and punchy') and the AI mastering engine builds and executes the full signal chain automatically.
- Spotify Reference Mastering: Paste any Spotify link to match the loudness, tonal balance, and stereo width of a professional reference track.
- Stem Splitter & Vocal Remover: Separate audio into individual stems — vocals, drums, bass, and more — with pitch, tone, BPM, and mix controls plus full stem downloads.
- AI Mastering Engineer Personas: Switch between AI engineer profiles such as Sophia (smooth and clear) or Marcus (Skrillex-inspired) to match your genre and style preferences.
- Cross-Platform Mobile App: One subscription unlocks the full mastering and stem splitting workflow on web, iPhone, iPad, and Android for seamless on-the-go production.
Use Cases
- An independent musician uploads a bedroom-produced track, types 'warm vintage sound, suitable for vinyl' and receives a streaming-ready master without hiring a mastering engineer.
- A DJ or producer pastes a Spotify link from a chart-topping track as a reference to match its loudness and tonal profile before releasing a new single.
- A content creator uses the free vocal remover to strip vocals from a licensed song and create a karaoke or instrumental version for social media videos.
- A music producer uses the stem splitter to isolate the drum track from an old recording for sampling in a new production.
- An artist uses the Visual Creator to generate matching cover art and promo visuals immediately after mastering a track, streamlining the full release workflow.
Pros
- Natural Language Workflow: Using text prompts to direct mastering is highly intuitive and removes the need to understand complex audio engineering terminology or signal chain settings.
- Spotify Reference Integration: Pasting a Spotify link as a reference gives artists an immediate benchmark for loudness and tone, making it easy to compete sonically on streaming platforms.
- All-in-One Suite: Mastering, stem splitting, vocal removal, visual creation, and free utility tools are all bundled under a single subscription, reducing the need for multiple paid services.
- Free Preview Without Signup: Users can try a free master preview without creating an account, lowering the barrier to entry and letting artists evaluate quality before committing.
Cons
- Subscription Required for Full Access: The free tier is limited to previews; downloading masters, using stem splitting with full controls, and accessing mobile apps require a paid subscription.
- AI May Struggle with Highly Complex Mixes: For tracks with unconventional arrangements or genre-bending production, prompt-guided AI mastering may not match the nuance a seasoned human engineer could provide.
- No DAW Plugin Integration: SoundBoost operates as a standalone web and mobile app, so there is no native plugin for popular DAWs like Ableton, Logic, or FL Studio.
Frequently Asked Questions
How does prompt-guided mastering work?
You upload your audio track and type a description of how you want it to sound — for example, 'punchy low end, wide stereo field, suitable for clubs.' The AI mastering engine interprets your prompt and builds a complete signal chain including EQ, compression, and loudness optimization, delivering a polished master in seconds.
Can I use a reference track from Spotify?
Yes. Simply paste any public Spotify song link into SoundBoost and the AI will analyze the reference track's loudness (LUFS), tonal balance, and stereo width, then apply those characteristics to your master.
Is SoundBoost free to use?
SoundBoost offers a free preview of mastering results without requiring sign-up. However, downloading the final mastered file, accessing stem splitting with full controls, and using mobile apps require a paid subscription.
What is the Stem Splitter and how does it work?
The Stem Splitter uses AI to separate a mixed audio track into individual components such as vocals, drums, bass, and other instruments. You can adjust pitch, tone, and BPM for each stem and download them individually for remixing or creative reuse.
Does SoundBoost work on mobile devices?
Yes. SoundBoost has dedicated apps for iPhone, iPad, and Android. A single subscription syncs your workflow across all platforms, so you can master tracks and split stems on the go.
