With this app, you can select input in DAWs like Cubasis where input selection is not available. Please mute within this app and turn on the microphone.

Description

Use your iPhone/iPad as a microphone and output sound to headphones or speakers. You can also use it to record audio instead of playing sound.
The app comes with four built-in effects. Stereo input is available on compatible devices only.

Please note that this app was created just for my personal use, and I cannot guarantee its performance on devices I do not own.

Included effects:

  • Pitch Shifter
    You can adjust the pitch in semitone increments.
  • Chorus
    Applies a stereo chorus effect. Choose from a selection of presets.
  • Reverb
    A built-in reverb effect provided by iOS/iPadOS. Choose from a selection of presets.
  • 10-Band Equalizer
    An equalizer with 10 frequency bands. You can emphasize or attenuate specific ranges of sound.

Supported devices with stereo input (unconfirmed):

  • iPhone XS or later
  • iPhone SE 2nd generation or later
  • iPad Pro 11-inch 1st generation or later
  • iPad Pro 12.9-inch 3rd generation or later
