Black Box Enhancement
for Voice Recorders
In almost every commercial aircraft, there are several microphones built
into the cockpit to track the conversations of the flight crew. These
microphones are also designed to track any ambient noise in the cockpit,
such as switches being thrown or any knocks or thuds. Most magnetic-tape
CVRs store the last 30 minutes of sound. They use a continuous loop of tape
that completes a cycle every 30 minutes. As new material is recorded, the
oldest material is replaced. CVRs that used solid-state storage can record
two hours of audio. Similar to the magnetic-tape recorders, solid-state
recorders also record over old material. MASC™ technology, can
dramatically increase the storage capacity of such devices while not
sacrificing quality. With a mere 64MB of storage available MASC can store
upto 21.5 hours of voice at telephone line quality.
Digital Audio Tape
Both DCC tape or Minidisc use data compression. The quality of DAT
format is such that professional studios very quickly adopted it and made it
the digital standard for recording. Moreover, DAT offers a comfort of use
infinitely higher than that of an analog tape. MASC™
technology, can improve upon the already excellent technology by
further condensing the size of the audio while maintaining superb quality.
Mass Storage
MASC™
technology, can dramatically increase the storage capacity, access and
retrieval of mass storage devices including jukeboxes, tape libraries,
magneto optical, raid storage and management software. MASC
