Understanding Sound File Size Calculations

What is the bit rate of an audio file with a sampling rate of 44.1 kHz, 16 bits per sample, and 2 channels (stereo)?

• 1411.2 kbps

• 705.6 kbps

• 320 kbps

• 128 kbps

Which of the following is a lossless audio file format?

• MP3

• AAC

• WAV

• OGG

How does increasing the sampling rate affect the quality of an audio file?

• It decreases the quality

• It has no effect on quality

• It increases the quality

• It makes the file unplayable

Which file compression method is typically used to reduce the size of audio files without losing quality?

• Lossy compression

• Lossless compression

• Data encryption

• Data deduplication

If an audio file has a duration of 3 minutes and a bit rate of 128 kbps, what is the approximate file size in megabytes (MB)?

• 2.88 MB

• 5.76 MB

• 11.52 MB

• 23.04 MB

Which of the following is NOT a common audio file format?

• FLAC

• JPEG

• AIFF

• ALAC

What is the effect of increasing the bit depth of an audio file?

• It decreases the dynamic range

• It increases the dynamic range

• It decreases the file size

• It makes the file incompatible with most players

Which unit is used to measure the sampling rate of an audio file?

• Hertz (Hz)

• Bits per second (bps)

• Decibels (dB)

• Bytes

What is the relationship between audio file duration and file size?

• Longer duration always means smaller file size

• Longer duration always means larger file size

• Duration has no effect on file size

• Duration and file size are inversely proportional

Which of the following is a lossy audio file format?

• FLAC

• WAV

• MP3

• ALAC
