WAV MP3 変換 フリーソフト

Does converting to MP3 cause a decline in sound quality?

MP3 is a compression technology that reduces the capacity by cutting data in the bandwidth inaudible to humans. Therefore, although it is said that theoretically there is no change in sound quality (because it is not audible to the ear), sound quality is actually degraded. The sound quality was poor due to the MP3 encoding and bit rate that had just appeared, and it was a convenience at the expense of sound quality.

Recently, however, high bit rate MP3 encoding and improved encoding quality have improved the sound quality considerably, and it can be said that the sound quality has not deteriorated to the extent that one should be pessimistic about MP3 encoding.

However, depending on the encoding software and playback environment (an audio environment capable of reproducing a wide bandwidth), the sound quality degradation of MP3 may be more pronounced.

Sound quality degradation caused by MP3 often appears as changes such as a narrow soundstage and lack of a sense of three-dimensionality or airiness, rather than as muffled sound or noise.
