BassLane is a GREAT little utility plugin! If you have issues with a certain area of the spectrum being too wide, this is the solution for you.

For instance, you're mixing live drums but don't like the wide sound of the kick and/or snare. Pop this on the overheads, turn the width knob to mono, and select a frequency between, say, 300 Hz and 1 kHz (or whatever). Instantly tightens up the low end of the kit while preserving the space of things like hi-hats and cymbals.

Another application is wide synth basses, which are common in modern soft-synths. Use BassLane to make the lows and mids dead to center while leaving stereo content in the upper region.

Yes, this stuff can be accomplished with a standard filter plugin and multiple tracks, but it's a pain in the butt. BassLane makes it quick and easy.

No complaints about the interface, it's straightforward and simple. You can listen to the dry and wet portions of the signal, to quickly tell how the plug is affecting the material.

All in all, I find this an indispensable mixing tool, and best of all it's free!

I recently discovered Basslane when I was looking for a way to center/mono the deep bass frequencies of a Chapman Stick track I had recorded that featured a tempo-delay on it, while leaving the upper frequencies unaffected in the stereo field. Originally the track had everything ping-ponging left and right and when mixed with the backing tracks, the deep bass notes were completely lacking in punch, as you usually want bass as close to center to achieve that.

Basslane was the perfect solution for this: after setting the cutoff frequency of its LPF (the pre/post monitoring options really help with this) and collapsing just frequencies below that to mono, the deep bass tones became solid and punchy while leaving the upper frequencies to bounce around in the stereo field.

I imagine this could also be really useful for situations where you have a full stereo mix of a song where the bass was recorded in stereo and lacking punch. Running such a pre-mixed track through BassLane would let you zero in on the bass frequencies and pull them in towards center.

Highly recommended. :-)
