#1
Front (Question)

Analogue Sound Waves and binary:

Back (Answer)

• Analogue sound waves must be digitally recorded and stored in binary. • To record the sound, the amplitude of the analogue sound wave is measured and recorded in binary at specific intervals.

#2
Front (Question)

Sampling an Analogue Sound Wave:

Back (Answer)

• Digital sampling is discrete (separate) and not continuous like analogue waves. • To get the highest quality sound, many samples are taken to recreate the analogue wave as closely as possible.

#3
Front (Question)

Sample Rate:

Back (Answer)

• Number of times per second the amplitude of the sound wave is measured (kHz).

#4
Front (Question)

Higher Sample Rate Advantage:

Back (Answer)

• The higher the sample rate, the better the audio quality as the digital data closely resembles an analogue wave.

#5
Front (Question)

Higher Sample Rate Disadvantage:

Back (Answer)

• Higher sample rates result in larger file sizes because more data is stored for each individual type.

#6
Front (Question)

Bit Depth:

Back (Answer)

• The number of bits available to represent each sample.

#7
Front (Question)

Advantage of having higher bit depth:

Back (Answer)

• More bits are available to be used for each sample. - Therefore, the quality is often higher as the wave more closely resembles an analogue wave.

#8
Front (Question)

Disadvantage of having higher bit depth:

Back (Answer)

• File size will also be larger as each sample stores additional bits.

#9
Front (Question)

Sound File Size calculation:

Back (Answer)

• Sound file size = sample rate x bit depth x duration (seconds). • Divide by 8 to convert to bytes.
