Is SACD All Hype?

Article Written By: ShaneRofrigues

Today's audiophiles and music lovers have wide arrays of options when it comes to music listening and recording. The latest innovations in home audio are Super Audio Compact Disc and DVD-Audio. Each of this has its distinct leap from present CD format technology, in which, each comes with its own great quality sound and storage capacity. SACD saves the data differently from the normal CD encoding. Typical CD encode by capturing the analog signal and saving it digitally.andnbsp; The CD data is read by the CD player and its signal is interpolated. This approximate value is converted and this soundwave is fed to the pulse code modulation process which is hear as music by the amplifier.

Unlike the approximations done with normal CDs, DVD-Audio has a higher fidelity of sampling speeds. CD offer at 44.1kHz and 16 bit. Meanwhile, DVD-Audio has settings at 96 kHz, 24 bit and both six and two channels.andnbsp; DVD-Audio offer other advantages over CD because of the storage capacity. Unlike normal CDs, DVD-audio can include other cool stuff like, photos, video clips, artist bios and musical lyrics to accompany the higher quality music. On the other hand, SACD features new technology known as DSD or Direct Stream Digital, which is touted as the andquot;PCM killerandquot; by two huge companies, Philips and Sony. Direct Stream Digital enhances music resolution to an admirable degree, even greater than DVD-Audio, by means of following closely to the music's original waveform.

Using the DSD technology is able to recorded the music at higher sampling rates. It no longer has to interpolate the data to contain the sound waves like PCM methodology. In addition to the better sound quality, the SACD format offers higher storage capacity. Head to head, SACD is six times more capacity than the traditional CD.

When comparing the sound quality of the music, SACD is warmer and smoother because the DSD capture more musical data than the Pulse Code Modulation (PCM). The sound is fresher and reproduces a better amibience. By using six channel instead of the normal two channels, SACD audio reproduction is fuller and has more added realism. It should great when played on a 5.1 channel home theater system.

Although much better in sound quality and reproduction, the cost of new audio equipment may be slightly out of some people's budget. The great thing about SACD and DVD-Audio players is that they also can play CD and DVD-Video formats. No need to double up in equipment. Overall, if you truly love the sonic fidelity of more data and smoother tone, why not consider adding a SACD player to you system. It makes an awesome addition to your home theater system.
