Digital Recorder
Digital Recorders
In digital recording, the analog signal of video or sound is
converted into a stream of discrete numbers, representing the changes in chroma
and luminance values (video) or air pressure (audio) through time, thus making
an abstract template for the original sound or moving image.
The most recent and
revolutionary developments have been in digital recording, with the development
of various uncompressed and compressed digital audio file formats, processors
capable and fast enough to convert the digital data to sound in real time, and
inexpensive mass storage.
Digital recording and
reproduction converts the analog sound signal picked up by the microphone to a
digital form by a process of digitization, allowing it to be stored and
transmitted by a wider variety of media. Digital recording stores audio as a
series of binary numbers representing samples of the amplitude of the audio
signal at equal time intervals, at a sample rate so fast that the human ear
perceives the result as continuous sound. Digital recordings are considered
higher quality than analog recordings not necessarily because they have higher
fidelity (wider frequency response or dynamic range), but because the digital
format can prevent much loss of quality found in analog recording due to noise
and electromagnetic interference in playback, and mechanical deterioration or
damage to the storage medium. A digital audio signal must be reconverted to
analog form during playback before it is applied to a loudspeaker or earphones.

We use Olympus Digital Voice
Recorder; it lets us capture over 272 hours of audio in high-quality stereo
sound with the compact style. Easily store and organize files and transfer them
to a PC with the easy-to-use "USB Direct" design. Simply plug the
recorder into a computer, with no USB cable necessary, for easy downloading of
audio files, documents, image files and more.
It’s important for a
Paranormal Investigator to do an investigation with the proper tool. We attach to the Olympus Digital Recorders, a
stereo or a Noise Cancellation Microphone is an ideal accessory
to have around when background noise may be a problem.
