Our verdict on Fire Lit AI Mastering
Fire Lit AI Mastering is a free web tool for automatically mastering finished music. It suits creators who want a quick local workflow without creating an account or sending audio to a server. Users drag in a WAV or AIFF file, choose processing stages, compare the original with the mastered version, and download the result. Stereo and mono files are supported, making the tool suitable for common finished-mix workflows rather than broader production tasks.
Its strongest feature is control over the mastering path. Users can select high-pass filtering, tone cleanup, glue compression, and loudness normalization, or choose loudness-only processing when tonal changes and compression are not wanted. A/B comparison provides a direct way to review the original against the processed file. The published workflow also applies a -1.0 dB True Peak ceiling during normalization, while the loudness target is set to -9 LUFS. That fixed target keeps the process straightforward but gives less flexibility to creators working toward other loudness goals.
Fire Lit AI Mastering is a good fit for fast, uncomplicated mastering of stereo or mono WAV and AIFF files, especially when local browser processing and no sign-up access matter. Its narrow format coverage and web-only delivery make it less suitable for workflows that require broader file support or more specialized mastering options. It also focuses on finished-file processing: the available feature set centers on selectable mastering stages, comparison, and loudness control rather than reference-track matching or stem-based work. Choose it for a focused free workflow; choose another tool when mastering requires wider format or production coverage.
