Alienbrain vs Layer Audio Cleanup

Alienbrain has no write-up on Specifiction yet; its figures are above.

Layer Audio Cleanup is a freemium audio-processing tool available through the web, an extension, and an API. It removes background noise and music, isolates voice, separates a target sound with the residual, and supports trimming, mixing, volume, and speed adjustments. Users upload a recording, select a cleanup tool, review results, iterate, and export or continue into other Layer features. The feature is described for game-production workflows such as voiceover pipelines, voice-cloning preparation, live operations, and reference or legacy audio. Processing is batch-based and accepts audio input. Layer uses Creative Units for consumption rather than per-seat fees. The Free plan costs nothing, billed monthly, with core features and free Creative Units through a rewards program. Studio costs $10 a month, billed monthly, and includes 300 Creative Units, 10% rollover, and unlimited team members. Enterprise pricing is custom.
