automixer.ai vs Offtrack

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.

Offtrack is an AI DJ app that shortens songs and mixes them with transitions. Smart Mix trims tracks, queues songs based on how they fit together, and creates transitions; Highlight Mode focuses playback on song highlights. On iOS, users can adjust highlight lengths, edit the queue, save mixes as playlists, sort tracks by BPM or energy, and filter explicit songs. The iOS app works with Spotify Premium, Apple Music, TIDAL, SoundCloud Free, a local music library, and CarPlay, though catalogue availability varies: Spotify Premium and Apple Music are partial, TIDAL is full, and SoundCloud Go+ tracks are unavailable. Android supports Spotify Premium and SoundCloud Free, but its FAQ lists offline playback, EQ, saved transition points, and saved mix order as not yet available. Offtrack can recommend tracks matching a listener’s taste and add them to a mix. The Free plan includes unlimited Smart Mix and Smart Queue, limited Highlight Mode plays, and discovery of up to 300% new songs. Pro is $4.99 a month and includes unlimited Highlight Mode plays.
