Adjusting the sound

The player has various settings for adjusting the sound. There are two options to adjust the sound.

  • “Sound adjustment” app.
  • The sound adjustment screens in “Music player”.

The following are instructions for using “Sound adjustment” app.

  1. On the [WALKMAN Home] screen, tap [Sound adjustment].
  2. Swipe the screen to the left or right to select the sound adjustment.
  3. Adjust the sound by following the onscreen instructions.

You can set the following sound adjustment.

  • Direct Source
    This setting outputs the file’s original sound quality directly without applying any sound effects.
    Turn on this function to listen to music without processing the audio signals. This will be effective when you enjoy High-Resolution Audio content. On one of the sound adjustment screens, tap the [DIRECT] switch to turn this function on or off.

  • Equalizer
    You can select an equalizer setting to suit your mood or current activity. When the switch is set to [ON], tap [Preset] and select the desired preset, then tap [OK] to apply.
    [Custom 1] and [Custom 2] are the user presets. Select [Custom 1] or [Custom 2] and tap [OK] to apply. Then, tap [ADJUST] to customize the equalizer setting.

  • DSEE Ultimate™
    This function upscales the sound quality of audio files. The sound quality will become almost equal to that of High-Resolution Audio. The function reproduces the clear high-range sound that is often lost.

  • DC Phase Linearizer
    This function adjusts low-frequency phase shifts to reproduce the audio characteristics of analog amplifiers.

  • Dynamic Normalizer
    You can moderate the change in volume between tracks to minimize differences in volume level.

  • Vinyl Processor
    This function produces rich sound that is close to the playback from a vinyl record on a turntable.

  • ClearAudio+™
    This function automatically applies the recommended sound settings to the output sound.


  • Even if you tap the ON/OFF switch of each sound adjustment, the current state will be kept. You can compare the sound while switching the sound adjustments ON and OFF to adjust the settings.
  • You cannot select sound adjustments if you have turned on the following settings. Turn off the settings to enable the other sound adjustments.
