Stereo Designer Mini is an easy to use multi-purpose stereo shaping tool for Audiobus and Inter-app Audio. Create unique wide stereo image, "stereoize" a mono sound source, apply mid/side processing, independent high and low pass filters per channel, and more. Process synths, drum machines and hundreds of other apps by connecting through Audiobus. Use Stereo Designer Mini as an effect inside DAW apps such as Garageband, Multitrack DAW, and AudioShare using Audiobus or Inter-app audio. Stereo Designer Mini supports Core MIDI via the Camera Connection kit, USB MIDI interfaces, Virtual MIDI and WiFi connections. The MIDI Learn function lets you easily assign your MIDI controller's knobs and sliders to control Stereo Designer's effect parameters. 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.

KEY FEATURES 1. Ultra-clean algorithm. Less than -140 dB harmonic distortion across all settings 2. Clean and simple interface 3. Side chain input with full band and band limited modes 4. High-resolution spectrum analyser displays the input and output volume at each frequency ULTRA LOW DISTORTION COMPRESSOR ALGORITHM This unique envelope follower design ensures harmonic distortion of less than -140 dB for the full range of compressor settings. There is no cleaner compressor on the app store. SIDE CHAIN INPUT In host apps that support multi-input audio units you can use this app to achieve the pumping side chain effect typically heard in electronic dance music where the synth and other background instruments duck their volume in deference to the kick drum on every beat. The side chain input of this plugin has two modes. In full-spectrum mode each frequency band is compressed according to the volume of the full spectrum of sidechain input. In single-band mode each band is compressed based on the side chain level in only that frequency band itself. COMPRESSOR CONTROLS Each of up to four bands has eight compressor settings. They are input gain, output gain, attack time, release time, threshold, ratio, soft/hard knee, and wet mix.
