Frequently Asked Questions

What is stereo panning?

Stereo panning is the process of distributing an audio signal between the left and right channels of a stereo sound field. Panning left makes the sound appear to come from the left speaker, while panning right makes it come from the right speaker.

What is the difference between pan and balance?

Pan moves a mono signal between left and right channels. Balance adjusts the relative levels of an existing stereo signal. ChangerAudio uses true stereo panning, which works with both mono and stereo files.

Do I need headphones to hear the panning effect?

While you can hear panning with speakers, headphones provide the best stereo experience because they deliver sound directly to each ear without room acoustics interfering.

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device, ensuring 100% privacy.
