Linear phase filters are particularly useful in situations where the phase relationship between the various frequency components of a signal is important, such as: b. mixing or Mastering of music, where phase information can influence spatial perception and sound quality. They are often used when it comes to maintaining the transparency and naturalness of the sound. Linear phase filters are also useful in situations where Phase shifts should be avoided, e.g. B. when using Multiband compressors or -Limitersto shape the signal without affecting spatial perception.
