CORE CAPABILITIES

LOAD TRACKS.BUILD A MIX.

Timeline of tracks joined with an 8 second crossfade

01

CONTINUOUS MIXES

Join your tracks with adjustable crossfades from 0 to 30 seconds. Shuffle the order or use natural filename sorting, then set an exact duration or let the final track finish.

Timeline with a station ID inserted after every three tracks

02

RADIO ELEMENTS

Insert station IDs, jingles and sweepers between groups of tracks. Each element plays once before repeating, with short transitions that keep speech clear.

03

VIDEO + TRACKLIST

Export a 1080p WebM video using your artwork and a timestamped text tracklist from the same mix timeline. Choose either output or both.

Mix Builder turns a folder of audio into one long crossfaded mix. Set the transitions, choose the order and let the app handle the render, with optional loudness normalisation, stereo width and balance correction.

Made for background-music and radio-style programmes. Tracks keep their original tempo and pitch: Mix Builder does not beatmatch, sync BPM or match musical keys.
