According to a study by the Audio Engineering Library, MP3s can have a distinct effect on the “timbral and emotional characteristics” of the instruments involved.

Researchers compared responses to compressed and uncompressed music over ten emotional categories at several bit rates.

The results showed that MP3 compression tended to strengthen neutral and negative emotional characteristics of a song, which the study defines as “mysterious, shy, scary and sad”.

On the other hand, MP3s can dull positive emotional characteristics, such as “happy, romantic or calm”. However, they had no effect on songs that were categorised as “angry”.

The Audio Engineering Library suggest that the background noise added by low-quality compression could be what intensifies the negative emotions.

The research also found that some instruments are more affected by compression than others with trumpets the most prone to change and horns the least.
