Digital Waves are More Effective.

Digital, The More Efficient Wave.

Digital Waves are the better waves when it comes to CD's and records. When you listen to a record you hear static and "interference." However, when you listen to a CD it is usually a clear sound.

Digital Waves

Digital waves use a code of either 0 or 1. That's why CD's were created. Records don't have as good of a sound as CD's.

How does this Device work?

There are 783,216,000 bytes in a CD. A CD has one spiral for its data, going from the inside out. There are bumps on the track that store data. When the CD is played in a CD player the CD player reads the data stored in the bumps.

Records first start as a recording. Then, a lacquer is placed on a record cutting machine and as it rotates electric signals are sent to a needle which imprints the record.
