Summary

preFIX is a pre-mixing and audio alignment tool designed to be used at the beginning of the mixing process. It provides a set of features for cleaning up, fixing, and aligning audio tracks, addressing frequency correction, phase alignment, spatial stereo field corrections, and routing.

Features

• Comprehensive gate/expander with dedicated sidechain filtering path
• Frequency correction tools including high- and low-cut filters
• Phase alignment adjustments for stereo field enhancement
• Stereo field rotation and mono compatibility checks
• Routing options to separate track alignment from mixing
• Tools to reduce gate release tail distortions and control fast gate attack behavior
• Focus filters to shape low-frequency boost and high-frequency air or shimmer

Usage Tips

• Use phase alignment to improve stereo perception and focus stereo field
• Apply cuts carefully to preserve instrument body and overtones, especially for acoustic recordings
• Utilize the gate for tight control on drum tracks and subgroups
• Separate the preparation and alignment of tracks from creative mixing decisions, working first on track quality and alignment
• Use the mono routing option to check mono compatibility and adjust channel levels

Additional Notes

preFIX is intended for upfront mixing cleanup, not for restoration or drastic filtering. The emphasis is on optimizing tracks for mixing context, recognizing that poor source quality cannot be fixed by alignment tools alone.
