FabFilter Pro-DS app for iPhone and iPad

FabFilter Pro-DS is a professional de-essing plug-in. With its highly intelligent Single Vocal detection algorithm, it accurately and transparently attenuates sibilance in vocal recordings. Alternatively, set to Allround mode, its an equally great tool for high-frequency limiting of any material, like drums or full mixes. Combined with world-class metering and real-time signal visualization, Pro-DS is designed to fulfill all your de-essing needs.

The Pro-DS app filters the microphone input and plays it back in real-time. To use Pro-DS as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-DS will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
