Basslane

Basslane is the improved version of the original freeware classic used in countless productions to control the stereo width of low frequencies on tracks and mixes.

It’s a handy utility that allows you to narrow the stereo width of frequencies below a defined threshold. The unique Side Harmonics feature adopted from Basslane Pro allows you to inject upper bass harmonics to add definition and pseudo bass width without problematic stereo content in the subs.

The easy-to-use interface combines helpful metering and flexible monitoring for precise fine-tuning.

New & Improved

The updated version of Basslane adds support for both Windows and Mac (with native Apple Silicon support) and introduces new features. The unique Side Harmonics feature adopted from Basslane Pro adds upper harmonics to the side channel based on the mono’ed low-end.

This allows you to create stereo width that is musically related to the bass without adding problematic stereo in the subs. The updated user interface provides helpful stereo balance and correlation metering.
