Here's what users are saying: " With Stereo Designer, Christopher has created one of the most impressive/creative stereo enhancement processors I’ve ever had the pleasure to use. If there was a VST/AU version for the desktop then I’d buy it in a heartbeat…." - Music App Blog (www.musicappblog.com)  "Add depth to your sounds - This can help add a missing dimension to your music. Try running a synth or drum app through it. Use an audio interface to process guitars, hardware synths, or even a signal from your desktop DAW. It works really well with the developer’s other apps too. Great with Audiobus." - dmonterroso (AppStore review) In addition to Audiobus and Inter-app Audio support, Stereo Designer Mini can also process external instruments such as guitar, voice and synths by connecting a microphone or professional audio interface such as the Apogee Jam, ONE, or any iOS compatible USB audio interface. Guitarists can use our effects live by connecting the output of their audio interface to an amp.

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.
