Where it sits in the data

SoundBoost.ai's $21K MRR is higher than 96% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Entertainment” category (351 projects) it is higher than 97% (category median $207). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view: demand would come from musicians, audio professionals, mastering engineers, and starter bedroom producers who need mastering and audio-separation tools. Distribution would need to reach those buyers through search, music communities, referrals, app stores, and direct word of mouth.

The hard parts are audio quality, reliable processing across file formats, mobile access, and support for music-production workflows. Competition would come from other online mastering and audio-processing services, while regulation would matter if the service handles paid subscriptions, user uploads, or music rights.

Verdict: Needs real work.

One thing to take from it

The product combines prompt-guided mastering, reference tracks, AI mastering personas, stem splitting, vocal removal, mobile apps, and multiple export formats under an unlimited subscription. The site lists $4 per month and gives users free access to selected stem splitting and vocal removal tools.
