GNOME-Nano

Subminiature stereo digital voice recorder

Gnome-Nano is a new subminiature recorder. It is designed for very high-quality digital audio indoor and outdoor recording and recording in difficult acoustic conditisons.
APPLICATION

  • Law enforcement agencies: Recording during special operations, in police cars, etc.
  • Security companies: Recording inside cash-in-transit vans and for other safety reasons.
  • Emergency services: Tracking of rescue operations inside vehicles.
  • Legal practices and institutions, businessmen, etc.: Recording of important conversations, lectures and interviews operations.

FEATURES

  • Continuous high-quality mono and stereo recording with or without compression using a built-in microphone and/or one or two external microphones in the integrated flash memory
  • Automatic and manual gain control
  • Recording started/stopped manually or automatically (by signal level / timers)
  • Recording format: files *.wav
  • Built-in battery rechargeable from power supply (AC/DC 220V/50Hz) or USB computer interface


HIGHLIGHTS

  • One of the smallest professional recorders
  • Long duration of the recording
  • Nearly undetectable and insuppressible
  • Digital signature to protect the recorded data from modification
