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.
Regain tightness in the bottom of your mix by keeping low frequencies from kick drums, bass lines and other tracks centered in the stereo field. Stereo synth patches, drum tracks mixed from multiple sources, or tracks with delay, reverb etc will often result in a "muddy" mix if the low end is too wide. Just drop Basslane on the track and tuck in the bass as much as you like.
Experiment with stereo effects on tracks without worrying about losing definition and focus in the bass region. By inserting Basslane as the last effect in the chain you can stack all the wild effects you like on the track, knowing that Basslane will keep the low end under control.
Basslane Pro offers both narrowing and expansion of stereo width in the lows/mids using high fidelity linear phase processing for an uncompromised stereo image. On top of this, Basslane Pro adds novel solutions to preserve valuable musical content affected by width correction, extensive control over added stereo harmonics, and Unisum-powered dynamics for a beautiful low-end that translates everywhere.
