SoundBoost.ai review
A flexible mobile mastering service with guided revisions and a useful free tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SoundBoost.ai is an online AI music-mastering service for musicians, producers, mastering engineers, and bedroom producers. Users upload a mix, describe a target sound with text or select a catalogue reference, then receive rendered mastering revisions. The service combines AI mastering engineer profiles, adjustable intensity, effects and custom EQ with loudness, genre, peak and stereo analysis. It runs on the web, iOS and Android, and accepts WAV, MP3, FLAC, AIFF, AAC, ALAC, M4A, OGG, OPUS and several video formats.
Its pricing structure makes the service accessible for preview-led workflows. The Free plan includes track uploads and previews, prompt-to-mastering, and up to 10 revisions per project, but the full master cannot be finalized and downloaded there. According to the vendor's pricing page, Unlimited is shown at $4 per month when billed annually and adds unlimited mastering and stem splits, WAV, HD-WAV and MP3 exports, 15 revisions per track, and all effects. Unlimited Plus adds bulk mastering for up to 10 tracks, unlimited revisions, full-length previews and a priority queue. The published plans position Unlimited for individual track work and Plus for larger batches.
The standout feature is the revision workflow: users can compare versions with A/B comparison while adjusting mastering controls and using text prompts. Reference mastering can search SoundBoost's catalogue, while personal reference-file uploads are not supported. That makes the service a good fit for mobile creators who want guided iteration rather than a single automated render. It also offers related stem-splitting and audio-conversion tools, broadening its utility around production tasks. Choose SoundBoost.ai for accessible, prompt-led mastering across mobile and web; choose another service if personal reference uploads or explicit loudness-target controls are central to your workflow.
