For Suno and Udio creators

Auto MixA folder of generations in. One continuous mix out.

Suno and Udio give you great songs — at ten different volumes, in ten different tones, that hard-cut into each other. Auto Mix levels them, matches their tone and beat-matches the transitions.

No signup to preview · MP3, WAV or FLAC

What it does

Loudness matching

Every track to one LUFS target, with a before-and-after per track.

Tonal matching

Tone reconciled across generations. Harshness taken off.

Beat-matched transitions

S-curve crossfades on the beat. Optional bass swap and filter sweep.

Key and energy order

Sequenced on the Camelot wheel, not the order the files landed in.

Tracklist and chapters

Timestamped, formatted for YouTube chapters.

Video and Shorts

MP4 to 4K with title cards. Vertical 9:16 teaser.

What does it work with?

Suno, Udio, Riffusion, Stable Audio and Mubert, including export zips — or your own WAV, MP3, FLAC and AIFF.

Not to preview the first three tracks.

Is this mastering?

No. It is the step before — making separate generations sound like one release.
