Auto Recorder is a free Android app developed by Giuseppe Romano. It is a voice-operated recording app that starts and stops recording automatically when it detects sound of a certain threshold, saving valuable recording time by not recording periods when there is little or no sound.

One of the most impressive features of Auto Recorder is its smart voice-activated spy recording, which allows you to record conversations without anyone noticing. Additionally, the app offers a mic calibration recorder, live audio spectrum analyzer, and unlimited recording time. You can set the recording format to WAV (3GP, AMR, MP4), set the sampling frequency, and use the rear microphone. The app also supports background recording, allowing you to open other apps while recording, even when the display is off. You can share your recordings via Bluetooth, Drive, Dropbox, Email, Gmail, WhatsApp, and other apps.

Overall, Auto Recorder is a solid choice for anyone looking for a reliable and efficient voice-operated recording app. Its features are well-designed and easy to use, making it a great choice for both personal and professional use.
