What is amplitude in the context of sound waves?: The volume or loudness of the audio
What does 'bit depth' refer to in digital audio?: The number of bits stored for each sample
True or False: A higher sample rate means that the digital audio will be a more accurate representation of the analog sound wave.: TRUE
How does bit depth affect the quality of digital audio?: More bits per sample means higher quality audio
What is the sample rate measured in?: Hertz (Hz)
True or False: Digital audio can exactly replicate analog sound waves.: FALSE
Why do we sample analog sound waves when converting them to digital audio?: computers cannot store the infinite resolution of analog audio
What does increasing the bit depth do to the file size of an audio file?: It increases the file size
How do you calculate the file size of an uncompressed audio file in bits?: Sample Rate (KHz) x Bit Depth (bits) x Duration (seconds)
To convert the file size of an audio file from bits to bytes, what operation do you perform?: Divide the file size in bits by 8
What term describes the number of times an analog wave is sampled per second in digital audio?: Sample rate
What is the term for the perceived loudness or intensity of a sound wave?: Amplitude
How many unique amplitudes can a 4-bit audio sample represent?: 16
True or False: A sample rate of 8 KHz means 8000 samples are taken per second.: TRUE
Why might a digital audio file be a larger file size than another if they are the same duration?: It could have a higher bit depth
It could have a higher sample rate
How would a sample rate of 48 KHz compare to one of 44.1 KHz in terms of audio file size?: The 48 KHz file would be larger
True or False: The amplitude of a digital audio signal can be represented by a scale of 0 to 15 with a bit depth of 4.: TRUE
