Audio Week 1

WHAT IS A FREQUENCY: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasises the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency

WHAT IS IT MEASURED IN: One means that an event repeats once per second. A previous name for this unit was cycles per second (cps). The SI unit for period is the second.

WHAT IS SOUND: Sounds are vibrations that travel through the air and come in contact with our ears

What is analog audio? Analog audio is a physical medium of sound as in analog audio is made with vibrations and sound-waves. 

What scale is used in the measurement of analog audio? A logarithmic scale

What is digital audio? - Digital audio is a technology that is used to record, store, manipulate, generate and reproduce sound using audio signals that have been encoded in digital form.

What scale is used in the measurement of digital audio? - Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems.
