Haaze 2 is a 16 band stereo widening tool that utilizes three different methods of controlling the stereo width and spatial positioning of an audio stream: • Haas – adds a small delay to the left or right audio channel, creating the perceived effect of the sound arriving from the side that’s reaching the ear first. • Pan – alters the gain level on either audio channel. All 16 bands can be panned separately, so this method is quite equal to the “split EQ” function often found on various well-rounded equalizers. • MS Stereo – controls the output stereo width on each band, from normal stereo signal to mono. There’s also a view for controlling the output gain of all bands separately. New features from version 2.0 and later: • New and more transparent crossover filters • Haas: Better control for each band • Split EQ is now called "PAN" and provides much more control • MS Stereo • Gain • Visualization • Brand new and more intuitive UI for a better work flow. • Several factory presets. Full documentation available inside the app or at https://klevgrand.se/downloads/haaze-docs/ Audio examples and more info at https://klevgrand.se/products/haaze Haaze 2 works both as a standalone app and as an AUv3 plugin.
