Audio Format Wars

Before buying a new car, getting married, or adopting a new audio format

it is wise to ask a few questions, peer under the hood, and ask the advice of

someone you trust. Will the new format satisfy your needs not only now but,

also in the future? Will it look (and sound) as good on all the mornings after

you first met?

The analogue cassette is an old and trusted versatile friend that went

with you on those morning jogs and cruised in the car with you on Friday nights.

However, the powers that be, have declared our trusted friend to be in the last

phase of the life cycle. It's successor must sound better, work better, and

have new features such as a digital display for song titles. There are

currently two formats competing to be the consumers next choice for sound on the

go. They are Philips' Digital Compact Cassette (DCC) and Sony's Mini Disc (MD).

What exactly is digital recording? The definition is, "An electronic

format that is designed to duplicate sound, while affording extremely accurate

control over any changes you might wish to make in the recording" (Mclan &

Wichman,1988). In simple terms it means that the digital circuitry samples the

signal and then reproduces what it has seen. The quality of the recording

depends on the sampling rate of the machine. The sampled signal is then encoded

to the tape or disc in 1's and 0's, just like a computer disk drive would encode

information. However, the biggest advantage of digital recording is the fact

that it eliminates tape "hiss" that is usually found present in analogue

recordings.

In the Eighties, a Philips invention captured the limelight. The

Compact Disc introduced us to a new era of digital sound, or "perfect sound."

In the nineties another Philips invention has taken centre-stage, the Digital

Compact Cassette (DCC). DCC is the marriage of the analogue cassette to Digital

Audio. Together they form a union that combines perfect sound, high convince and

greater versatility. " DCC is a medium on which audio information is digitally

encoded and which reproduces CD quality sound" (Philips Electronics, Sound &

Vision, 1995). A number of features have been incorporated into DCC tapes and

decks to achieve CD like sound and convince. DCC decks can locate a chosen

track on either side of the tape because track and time codes are recorded on

the tape. This combined with autoreverse, which is standard on all DCC decks,

makes track access effortless but, not as fast as a CD. Another attractive

feature of DCC is the text mode.
