ZEROLINE: Free Gain Staging Plugin by Tonecraft Tokyo
Tonecraft Tokyo has released ZEROLINE, a precision free gain staging plugin built to calibrate track levels before the mixing phase begins. The utility is completely free to download in VST3 and AU formats for compatible digital audio workstations on macOS and Windows. It helps producers set balanced starting points across multitracks, imported sample loops, and raw vocal recordings.
Automated Level Balancing and Workflow
Gain staging remains one of the foundational steps in audio engineering, ensuring that downstream processors such as analog-modeled compressors and saturation plugins hit their optimal sweet spots. ZEROLINE streamlines this repetitive task by analyzing incoming audio signals and matching them to a clean target reference level. Rather than manually nudging clip gain or channel faders on dozens of tracks, engineers can balance input levels across an entire session in seconds.

The plugin interface focuses entirely on zero-friction operation, featuring:
- Target reference level adjustments for customized mixing headroom
- Fast level matching across vocal stems, synth lines, and sample packs
- Peak and RMS monitoring to prevent accidental clipping and distortion
- Minimal CPU footprint suitable for loading across every channel in a session
- Clean 64-bit internal processing with zero unwanted harmonic coloration
