Fourfold Desk

AI generated four channel browser stem mixer with live tone controls, timed entrances and stereo mix export.

Screenshots

Screenshots supplied by the seller.

Description

AI generated. Fourfold Desk combines four original synthesized stems or local audio files in a focused browser mixing workspace. Set each channel entrance, level, pan, polarity, mute and solo.

A low shelf, mid bell and high shelf shape each stem. Live EQ, faders and pan respond during playback. The master uses fixed soft saturation to control the mix. Inspect channel meters and mix output while comparing the original stems.

Render a stereo WAV or save a mixing recipe. Recipes validate source fingerprints and require the same source files rather than embedding large audio. Four original rhythm, bass, chord and melody stems provide a complete starting session.

Known limitations

Standalone browser mixer. Four channels and one audio clip per channel. Local files are limited to 20 MB and 45 seconds each; decoded at 44100 Hz, mono duplicated and only the first two channels retained. Entrances range from 0 to 16 seconds. EQ uses fixed centers of 180, 1000 and 4500 Hz. A rendered mix includes a one second tail. Live loop has that tail between passes. The master saturator changes high levels and is not a transparent limiter. No recording, automation or DAW synchronization.
