Which file format retains the original sound quality but has a large file size?

The WAV file format is known for retaining the original sound quality due to its uncompressed nature. Unlike formats that use compression algorithms, such as MP3, WAV files store audio data in a way that preserves every detail and nuance of the sound. This results in higher fidelity playback, making WAV ideal for professional audio applications, music production, and situations where sound quality is paramount.

The trade-off for this sound quality is the larger file size associated with WAV files. Since they do not compress the audio data, they take up significantly more space on storage devices compared to compressed formats. This makes WAV files less convenient for casual listening or streaming, where smaller file sizes are often preferred to save bandwidth and storage.

In contrast, other options like MIDI (which does not contain actual sound data but rather instructions for producing sound), MP3 (which sacrifices some audio quality for a smaller file size through compression), and HTML (which is a markup language for web pages and does not store audio directly) do not meet the requirement of retaining original sound quality alongside having a larger file size. Thus, the WAV file stands out as the appropriate choice in this context.
