Analogue Sound

In Chris's lesson today we looked at analogue recording methods over digital. Analogue sound is a higher quality debatably because the record uses vibrations to create real physical sound which is then amplified this sound is more natural to us humans.
The sound is played because different wave lengths are scribed onto a surface as a physical texture which cause vibrations in the needle which then produces the correct wavelength which is amplified for us to hear. This is the method used for record players that use a needle to play the sound from a disc.
Another analogue recording method uses magnetic tape rather than a vinyl disc used for record players. To record the quality sounds the thicker the tape and how slowly it is winded define the quality of the sound slower and thicker means better quality unlike modern CD recordings.
