Tone Projects Basslane x86 x64 VST3 AU AAX WiN MAC [FREE]

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.
