Good to know

  • Five bands: bass (60 Hz), low mids (230 Hz), mids (910 Hz), presence (3.6 kHz) and air (14 kHz), each from −12 to +12 dB.
  • Boosts are followed by a gentle limiter, so the result doesn't distort.
  • Video files keep their picture as it is; only the sound is changed.
  • For hiss and hum in speech, Remove Background Noise works better than an equalizer.
