DOTEC vs StereoLoco

DOTEC-AUDIO AUMediaPlayer is a media player that lets you apply Audio Units Extension (AUv3) effects while playing music and video. Use the Audio Units included with iOS or compatible AUv3 effects available separately on the App Store. Build a chain of up to eight Audio Units, rearrange them, and bypass individual effects. Effect-chain settings can also be saved and recalled. Import music and video from your music library, the Files app, or your photo library, then listen while your effects are applied. Processed media can be exported in MOV, MP4, WAV, or M4A format. Preview DOTEC-AUDIO products before you buy Try the features and sound of DeePopMax, DeeEQ, and DeeTrim inside AUMediaPlayer before purchasing the full AUv3 products. During playback, every parameter and preset is available without a time limit. When a built-in product preview is used in the effect chain, export is limited to the first 30 seconds.

Concept: The app is an audio effect which makes a monaural audio signal "stereophonic". Usage: Just insert this plugin in AUv3 host and effect your audio source. There are 2 sliders, one of which ("buffer size") determines incoming audio sample size 2^N (default N = 11), the other ("stereonize") adjusts stereo image (from -500 to 500. Double-click will return 0). The standalone supports IAA, so you can use this app together with a popular app "AudioShare". System Requirements :  stereo output: plug a headphone/mic or some audio interface. AUv3 host: the app also works as AUv3 plugin.
