JAX Stereo Tool (AU) vs Multiband Haas Effect

JAX Stereo Tool is a visual Audio Unit plugin for manipulating the stereo image of digital audio. The distribution app comes with an embedded plug-in (Audio Unit) that is available system-wide when you install the app. You should be able to use it with most supporting host applications. Audio Units are Apple's recommended method for providing shared audio effects for applications and audio editors. You can load the plugin into any host application that supports at least stereophonic audio effect plug-ins (in Audio Unit format - AUv3) with its own user interface. JAX Stereo Tool has its main use as a mastering effect, that allows you to modify the stereo image of your audio by narrowing or widening it in a controlled manner. That is, the stereo output can be continuously adjusted in the basic function of pure mono to very wide stereo. This happens in real time and you can observe the result with the integrated correlograph, controlling and optimizing the audio thanks to this helpful additional visual information. One of the special functions of JAX Stereo Toolis to recover lost mono-compatibility. This technique is conceptually quite simple and effective but somewhat difficult to understand. Please read the manual for further details. The manual is shipped with the app or available on the product website at https://audio.digitster.com

Haas effect is a micro-delay applied to either the left or right channel of audio (but not both). This simple effect creates a realistic and natural-sounding increase in the width of the stereo field that still sounds good when mixed back to mono. It is the most simple and effective way to take a mono input and make it sound like stereo. But Haas effect has some problems. First, it can create phase cancellation problems in the bass frequencies, causing them to loose volume. Second, it can sound a bit artificial at high frequencies. This multi-band Haas effect plugin is a simple way to get the stereo width you need in the midrange frequencies without loosing the impact of the bass or making the treble sound phasey. You select any number from one to four bands, each with its own separate Haas delay setting and adjustable crossover frequencies. This makes mono audio sound wide and spacious while preserving the original tone and spectrum transparently.
