GHOST MATCHIllustration
Saved reference Measured sound
LISTEN. COMPARE. ADJUST.
Three ways to get into your sound.
Ghost Match
Save a reference with your phone’s microphone. Play the same test signal from a supported player on the phone through your target speakers. Ghost Match tests small corrections to the phone’s playback EQ against what the mic hears.
Live Tune
Watch the microphone spectrum beside your saved reference. Use the comparison to guide adjustments on an external equalizer.
A REFERENCE, NOT A GUESS
Bring the sound.
Keep the context.
- Capture what you like.
Play a consistent test signal and measure at your listening position.
- Compare in the next space.
Use the same phone and signal so the comparison stays meaningful.
- Adjust, then listen.
Review the changes and judge the result with your ears.
BEFORE YOU GET STARTED
A few things to know.
Can I download GhostCurve yet?
GhostCurve is in development and compatibility testing. A public Google Play release and download link will be announced here when available.
Does Ghost Match adjust an external equalizer?
Ghost Match adjusts the phone’s playback EQ when it can connect to a supported audio session. Live Tune shows microphone measurements and a saved reference to guide changes you make manually on external equipment.
Does the microphone stay on while I listen?
Playback EQ can run with the microphone off. The EQ and Live Tune views can start foreground measurement according to your settings and microphone permission. You can pause measurement, and leaving the app stops microphone use. The current prototype does not save microphone audio recordings.
