E-Chorus is a four-voice ensemble chorus for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. Four modulated delay voices use different base delay times and rate offsets to create a dense, smooth sound without relying on one obvious sweep. The result can move from focused widening to a spacious animated wash while keeping the source present. FEATURES - Four independently timed ensemble voices - Rate control from 0.1 to 5 Hz - Equal-power Depth dry/wet blending - Width control from focused mono to spacious stereo - Instrument and line input modes - Output level from -12 to +12 dB - Optional 2x and 4x oversampling - Mono and stereo processing - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use, shared between the standalone app and AUv3 extension. Demo time advances only while audio is actively processing. A one-time, non-consumable In-App Purchase unlocks unlimited use in both formats. Restore Purchases is available in the standalone app. E-Chorus works well on synthesizers, electric piano, guitar, vocals, pads, and other sources that need width without losing their center.
