Portable High-Capacity Audio Recorder
Tonfarb 136GB Digital Voice Recorder
A compact voice-activated recorder for interviews, lectures, field notes and audio sessions requiring long recording capacity.
Clear recording with less background distraction
The Tonfarb A20 uses dual noise-reduction microphones and supports recording at up to 1536 kbps PCM. Its automatic noise-reduction system is intended to help produce clearer recordings in classrooms, meeting rooms, interviews and other environments where background sound may be present.
For paranormal investigators, it can serve as a conventional digital recorder for documenting spoken notes and conducting EVP-style audio sessions. Any unusual sound should be carefully compared with environmental noise, movement and nearby voices before conclusions are drawn.

Why investigators may find it useful
Long investigations can produce hours of audio. The combination of substantial storage, an extended battery, one-touch operation and portable construction makes this recorder convenient for investigators who do not want to repeatedly change memory cards or recharge their equipment.
Its A-B repeat and adjustable playback-speed functions can also help when reviewing a short portion of a long recording. For better evidence control, announce the time, location and names of everyone present at the beginning of each session. Verbally mark footsteps, whispered conversations, passing vehicles and equipment handling when they occur.
Important recording tip
Voice activation is convenient for meetings, but it may omit very quiet sounds or create abrupt starts in an audio file. Investigators conducting controlled audio sessions may prefer continuous recording at the highest practical quality. Test both modes before relying on the recorder during an investigation.
