Question Details

Given below are two statements about music files:

Statement I: A music clip stored in MP3 format would take up more memory than the same clip stored in WAV format.

Statement II: Music files stored in MP3 format are of better quality than files stored in WAV format

In the light of the above statements, choose the correct answer from the options given below.

Options

A

Both Statement I and Statement II are true

B

Both Statement I and Statement II are false

C

Statement I is true but Statement II is false

D

Show Answer

Correct Answer :

Option B

Both Statement I and Statement II are false

Solution :

The correct answer is: Both Statement I and Statement II are false.

Let's analyze each statement step-by-step to understand why they are incorrect:

Analysis of Statement I:
MP3 (MPEG-1 Audio Layer III) is a compressed audio format that uses "lossy" compression. This compression algorithm reduces the file size by identifying and removing sound components that are beyond the range of human hearing or are masked by other sounds. On the other hand, WAV (Waveform Audio File Format) is an uncompressed audio format that preserves all the original sound data. Because of this, an MP3 file is significantly smaller than a WAV file of the same recording—typically about 1/10th of the size. Therefore, a music clip in MP3 format takes up much less memory, not more, than the same clip in WAV format. Thus, Statement I is false.

Analysis of Statement II:
Since MP3 is a lossy compression format, some audio data is permanently discarded to achieve a smaller file size, which results in a reduction in overall audio quality. WAV files are uncompressed and lossless, meaning they retain the full audio frequency range and original recording quality without any degradation. Consequently, files stored in WAV format have superior audio quality compared to those stored in MP3 format. Thus, Statement II is false.

Conclusion: Since both Statement I and Statement II are incorrect, the option "Both Statement I and Statement II are false" is the correct choice.
