  • detect very high or low frequency sounds
  • detect very loud or soft level sounds
  • tailor the sound quality to increase or enhance enjoyment of music.

Manufacturers may use the following terms:

  • music programs
  • extended frequency range
  • extended dynamic range.

Frequency shaping

Makes the sound better, so it's more like what we naturally hear. Manufacturers may use the following terms:

  • binaural cue preservation
  • spatial cue preservation
  • streamed audio equalisation.

Frequency lowering

Frequency lowering uses technology to change the pitch of certain sounds so you can hear them more easily.

Manufacturers may use the following terms:

  • frequency lowering transposition
  • linear transposition
  • frequency compression.
