LANDR

LANDR is an online mastering service whose AI, trained on the work of human mastering engineers, analyzes an entire track and automatically produces a loudness-balanced commercial master. Alongside mastering, it bundles music distribution, samples, plugins, and collaboration into one subscription, fitting solo musicians and independent producers who want to finish post-mix work in a single place.

Its strength is the breadth of the workflow. As the longest-running AI online mastering platform, its output is ready for commercial use immediately, and with an ecosystem rating of 90 it extends beyond mastering into distribution and a sample library. Ease of use sits at 88, and the core appeal is that you upload a track and get back a polished master with no technical knowledge required. You can preview results on a free account before moving to the entry plan at 12.99 USD per month.

That said, it does not support Korean, so the interface and guidance are English-centric. No API is provided, so it is hard to slot mastering into your own automated pipeline, and downloads are limited on the free account.

In short, it is worth recommending to individual creators who want mastering, distribution, and source material solved with one subscription. Those who specifically need a Korean environment, or who want to automate the mastering process through code, are better off looking at other tools as well.
