Whether you need a quick voice amplifier, a karaoke microphone app, or a simple voice recorder, Mic To Speaker does it all in one lightweight app.

Completely free. Every feature — mic passthrough, recording, playback, sharing — is free to use, with no paywalls or locked functionality. The app is supported by ads only.

We take your privacy seriously — microphone access is used solely to power the app's core recording and passthrough features. See our privacy policy in-app for details.
