  • Q2
    What is the outcome of the ADC process?
    Analogue is compressed to smaller file formats
    Audio sounds are converted to analogue
    Soundwaves are represented in binary (digital)
    Digital sound is represented in analogue

  • Q3
    Why must analogue sound be converted to digital?
    So that computers can understand it in a binary format
    Because its easier for humans to understand
    To have a digital copy of the sounds
    So that it takes up less computer storage

    What is the sample rate?
    The frequency with which the sound changes in an audio recording
    The number of recordings you have of the same sound
    The size of the total audio sample
    The frequency with which you record the amplitude of the sound

    What is the sample resolution?
    The number of bits used to store each sample
    The frequency of the samples taken per second
    The range of rounds recorded
    The volume of the sound recorded
    30s

  • Q6
    What is the Amplitude?
    The loudest sound recorded in a sample
    The maximum height of sound wave from the middle of the wave to its peak or trough
    The frequency with which you record the amplitude of the sound
    The number of bits used to store each sample

  • Q12
    What happens is an audio file is compressed after conversion?
    The length of the recording in shorted, removing any silent parts
    The file sizes increases to match the maximum resolution
    The sample rate is reduced, reducing the resolution and file size
    The sample rate in increased, increasing the resolution and file size
