Controls for amplification, frequency balance and recording.
Live Amplification
Adjust microphone amplification from 0 to +40 dB. Start low and increase carefully.
Speech Clarifier (WDRC, PRO)
PRO boosts quiet voices with wide dynamic range compression (WDRC), without making loud sounds harsh.
Tune Your Sound
Six EQ bands, 250 Hz to 8 kHz. Five presets: Natural, Speech +, Highs +, Comfort and Night Nature, plus Custom. Manual adjustment requires PRO.
Real-Time Processing
Processes microphone audio in real time on your device, and keeps working with the screen locked.
Feedback Protection
When feedback is detected, the shield clamps gain to 0 dB. It does not replace safe volume settings.
Balance & Orientation
Adjust left/right balance, test the channels and swap them.
Auto-Leveler & Peak Protection
Softens sudden loud sounds while amplifying surrounding audio.
Noise Spectrum (RTA)
See the live spectrum and hints to lower a dominant frequency band or reduce volume if it is already cut.
Recording & Silent Recording
Save amplified audio. Silent recording keeps playback off and works without headphones. If headphones disconnect during recording, playback stops and recording continues silently.
Recordings Library
Free includes one saved recording plus a one-time bonus slot for watching a sponsor video. Delete an old recording to free space, or unlock an unlimited library with PRO.
Audio Devices & Routes
Headphones are required by default for live listening. Disconnecting them stops playback; an explicit bypass exists. Select the microphone and output route. On iOS, a Bluetooth headset microphone links input and output; USB routing may be locked by the system.
