Features of Snooper





  • Robust and stable sound recording engine
    The recorder engine is built to be resource efficient with low CPU and memory usage. It has evolved over time and is very stable and robust.

  • Flexible recording system
    The sound activated recorder has a flexible trigger window that allows the recording to start up to 10 seconds  before the actual trigger sound occur. Adjustable trigger sensitivity level and pre-recording DSP filters can be applied for better trigger accuracy.

  • Unique noise suppression system
    Will during a recording suppress noise according to a pre-recorded noise profile. Makes it easy to detect and trigger at really low sound levels. Perfect for use with laptops with internal noise etc.

  • MP3 and WAV formats
    Various settings available including bit rate, sample rate, mono, stereo, etc.

  • Exclusive Dual recording formats
    Record to WAV simultaneously as recording to MP3. Possible to record a  RAW untouched WAV file without any filtering etc along with the filtered and compressed MP3 file.

  • Dictation mode
    A special recording mode where all recordings are collected into a single file. The autosave function saves the recording after a selected time has elapsed. Setting the autosave to 30 minutes will generate a file 30 minutes after the first trigger occured. A maximum of two files an hour will be generated with autosave set to 30 minutes.

  • Frequency triggering
    Setup Snooper Professional to trigger a recording by a specific frequency. Use TwoToneSequential mode to trigger on common audio tones used by public pagers or control systems. It's even possible to trigger on a series of DTMF tones.


  • Hotkeys
    System wide user definable hotkeys can be set to control the program. Recordings can also be set to automatically start/stop when switching to/from screen lock.

  • Automatic gain control (AGC)
    The AGC will adjust the input sound level to an optimal value and thus produce a consistent output amplitude. This in combination with the Noise cancellation system makes it easy to record sound with low amplitudes.

  • Sound pressure level meter/logger
    Monitor sound pressure level (SPL) 24/7  with the built in SPL meter. View the measured sound/noise levels graphically with the built in viewer. In the graph you can see the parameters Lmax, Lmin, Lpeak and Leq which provides a very useful means of describing the sound levels.
    Amplitude data can be searched for and exported to an MS Excel compatible format for further analysis.

  • Pre-recording digital filters
    Adjustable digital filters (LP, HP, BP, Notch, 3-band equalizer) can be applied to the audio recording. This can be used to attenuate unwanted signals or noise from the audio recording.

  • Instant timer recording
    Right-click the recorder button to quickly add a timer recording in the selected recording mode.

  • File splitter
    Recordings can automatically be splitted and saved after a pre-defined file size or time duration.


  • FTP support
    Recordings and snapshot images of the SPL meter/logger can automatically be uploaded to an FTP-server. This makes it possible to view the graph and listen to recordings from remote locations using smart phones etc.

  • Email handling
    After the recording is saved the audio file can automatically be sent by email to designated address. You can also create voice mail with the integrated voice mail function. TLS/SSL encrypted connections are supported.

  • Scheduler
    Snooper can be setup to get activated in different recorder modes and with different recording devices at specific time and date.

  • Trigger event
    Play a selectable sound or start an external program when a trigger sound  occurs. Delete file after it's sent by email with a script, copy file to backup storage, database etc.

  • Smart storage
    All recorded sound files can be stored in a date folder hierarchy for easy organization of the sound files.

    Tip: Sync the folder structure with Dropbox, Google drive or similar service for remote access to the files from smart phones etc.

  • Encryption
    Snooper can after a recording automatically encrypt the recorded sound file (Snooper Professional has advanced PGP encryption). Useful when transferring the recording over internet by mail or FTP.

  • Frequency analyzer
    Built in Real time frequency analyzer (spectrum analyzer and octave analyzer) shows a detailed picture of the input sound signal.
