Its intuitive and well-organized interface makes it accessible to all users, from beginners to experienced professionals.
Snooper Professional voice activated recorder software user interface.
Sound/Voice activated recording
A voice activated recording (VOX) is automatically triggered when sound is detected above an adjustable threshold. The audio recording is then saved with a timestamp when there is silence.
Dictation recording mode
Sound activated recording mode where all recordings are captured and collected into a single file. Individual recordings can be located inside the file by time-stamps.
 Great for scanner and dictation recordings.
Stealth mode
Run Snooper in stealth mode or as a Windows service to keep it hidden from the taskbar and system tray. Ideal for background recording, with options for automatic start and stop based on system events.
Recording scheduler
Snooper can be scheduled to start and stop a recording at any time you set. It can also record on the fly for as long as you like without interruption.
Plugins
Post process your recordings with automatic Zip-compression, PGP encryption, email sending, upload to Dropbox or an FTP-server, execute external programs or execute your own plugin.
Use the MQTT-plugin to get status information about Snooper and to control Snooper states.
The Speech-to-text Plugin using OpenAI’s Whisper model can transcribe recorded speech to text automatically.
Sound editor
Use the built in sound editor to do simple adjustment of a recording.
Increase/decrease volume, remove unwanted sections, transcribe parts of a recording etc.
Noise suppression and automatic gain control
Suppress unwanted signals according to a pre-recorded noise profile. This in combination with the automatic gain control (AGC) can capture sounds with very low amplitude. Advanced users can use the frequency analyzer to help fine tune the setup with different filters to enable the recorder to be highly sensitive.
Remote monitoring
The Remote Monitor tool allows users to monitor instances of Snooper Professional, including Snooper Multi-Channel, in real-time. It enables listening to live audio, viewing the spectrum and octave analysis, and tracking the history of sound levels, including the start and stop of recordings.

Data Integrity
To make sure that the recordings are reliable, consistence and accurate over its entire life-cycle enable the Data Integrity plugin to guard your recordings.
Sound level logger
Use the built in sound pressure level (SPL) meter to document noise levels for over a longer period of time. This is often used for documenting dog barks or loud environmental noise over a day.
Multi channel recorder
The multi channel version of Snooper records multiple audio channels simultaneously.
