automixer.ai vs CRATELAB

automixer.ai is a web service that analyzes uploaded music and builds DJ sets with automated transitions. It accepts MP3, WAV, FLAC, and AIFF files, examining each track’s BPM, key, energy, and musical structure. For every transition, it generates and ranks three to five complete options across seven styles: smooth blend, filter sweep, drop mix, echo out, stem swap, vocal ride, and quick cut. It checks transition areas for vocal overlap and says it can reject a mix point or use EQ automation to separate vocals. Exports include MP3 at 320 kbps; paid plans add lossless WAV at 44.1 kHz. The site says exports use EBU R128 loudness normalization. Beatport features include purchase browsing, metadata import, and matching uploads by ISRC, with purchase access on Pro and Studio. Free allows three projects, six tracks per project, five monthly exports, and 1 GB storage. Pro is $14.99 a month; Studio is $29.99 a month.

CRATELAB is AI-powered DJ software for analyzing tracks, organizing crates, planning playlists, and syncing a cloud library. Its desktop analyzer performs local beat tracking, and the site claims tempo detection to ±0.5 BPM. It identifies keys using Camelot notation, assigns energy scores from 1 to 10, and maps intro, build, and drop sections on coloured waveforms. Mix tools include AI playlist generation, transition compatibility scoring, and an AI DJ coach for suggestions. Metadata can be exported as CSV or connected through the Sync page to Rekordbox, Serato, and Engine DJ. Audio stays on the user's computer unless sent to the cloud, while metadata syncs by default. Browsing, editing, and playback work offline, but local analysis needs internet access to verify the subscription. The Free plan is free, billed Forever, and requires sign-in. Pro is $9.99 a month, billed monthly, with 200 analysis credits per cycle; each analyzed track uses one credit and unused credits do not roll over.
