Snooper is a trigger-based sound and voice recording application for Windows, developed by Peter Skarin from Sweden. It comes with a large number of options and features, and offers multiple recording modes. Users can use it to quickly and flexibly record sounds from computer microphones. So it can be used to record meetings, monitor and record phone calls, record broadcasts, and even for espionage activities.

Snooper features a sound trigger, which ensures that there is no garbage time during the entire recording process. Recording starts automatically when sound exceeding an adjustable threshold is detected from the microphone; when silence occurs, recording is stopped and a timestamp is saved in the audio recording. Even better, it captures all recordings to a single file .

Snooper offers a stealth mode, so the program icon can be hidden from the taskbar. It supports starting and stopping recording at any preset time, and allows to use a frequency analyzer to fine-tune the noise suppression effect. It has a recording scheduler that allows you to set scheduled automatic recordings, and also provides a variety of tools such as filters, plug-ins manager, frequency analyzer, and sound editor.

The audio quality recorded through Snooper is very good, the original sound can be guaranteed to the greatest extent, and the audio files generated are very small and easy to save and transfer. Even better, it allows to automatically send the audio files via email to designated mailboxes, and you can also create voicemails using the integrated voicemail feature.

// Key Features //

Feature	Description
Robust and stable sound recording engine	The sound recording engine of Snooper is built to be resource efficient with low CPU and memory usage, the Snooper recorder system has evolved over time and is very stable and robust. Snooper is used in many critical installations like, airports, fire stations and radio stations e.t.c.
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	Suppress noise according to a pre-recorded noise cancellation profile. This makes it easy to detect and trigger sounds at very low levels, perfect for use with laptops with internal noise etc.
Scheduler	Snooper can be setup to get activated in different recorder modes and with different recording devices at specific time and date. Every Snooper Professional plugin can individually be set to be enabled during specified times and weekdays.
MP3, WAV and FLAC formats	Various settings available including bit rate, sample rate, mono, stereo, etc.
Exclusive Dual recording option	The dual recording option allows for recording to both WAV and to MP3 file formats at the same time. It is also possible to record a RAW untouched WAV file without any filtering etc along with a filtered and compressed MP3 file.
Dictation mode	A special recording mode where all sound activated recordings are collected into a single file. The auto-save function saves the recording after a selected time has elapsed. Setting the auto-save to 30 minutes will generate a file 30 minutes after the first trigger occurred. A maximum of two files an hour will be generated with auto-save set to 30 minutes.
Tone 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.
File splitter	Recordings can automatically be splitted and saved after a pre-defined file size or time duration.
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.
Encryption	Snooper can after a recording is completed automatically encrypt the recorded sound file (Snooper Professional has advanced PGP encryption). Useful when transferring the recording over internet by mail or FTP.
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.
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.
Frequency analyzer	Built in Real time frequency analyzer (spectrum analyzer and octave analyzer) shows a detailed picture of the input sound signal.
Trigger event	Play a sound or start an external program when a trigger sound occurs. Delete file after it’s sent by email, copy file to backup storage, database, FTP etc.
