## What is SonusQuest?

SonusQuest — Phone Monitor & DAF Tool

Turn your phone into an in-ear monitor. Record and play at the same time, so you can hear your own live stream in real time. It can be used for pronunciation training, reading practice, DAF correction, or as a voice recorder. It also works perfectly as an assistive listening tool for the hard of hearing.

Key Features
• Works with both wired and Bluetooth earphones
• Supports the phone's built-in microphone, wired earphone microphone, and lavalier microphone
• Hearing protection supported — automatically reduces output power when sudden loud sounds are detected
• Loop recording supported — generates multiple audio files of fixed duration
• Multiple levels of audio noise reduction supported. The intelligent noise reduction efficiently filters out irregular background noises, such as the crackling sound of typing on a keyboard, footsteps, tapping sounds, the hum of a robot vacuum, and more
• Supports both second-level delay settings and millisecond-level DAF delay settings
• Audio gain adjustment supported, making your voice sound purer and more pleasant to hear

Who It's For
• Pronunciation training
• Reading aloud practice
• DAF correction
• Daily use as a voice recorder
