Nu-Music Player

This music player lets you create custom playlists from songs on your device and apply effects in real time.
(This app registers links to songs in its playlists; song data is not imported into the app.)
Use it for learning music by ear, practicing instruments or vocals, language learning, and listening closely to speech.

■ Effects
- Speed change
- Pitch change
- 10-Band EQ (Equalizer)
- FX (Echo)
- Center Cancel / Center Emphasis

Tap the buttons (Player, Tune, EQ, FX) on the toolbar at the bottom to switch the controls displayed on the screen.
The app retains the effect parameters you set, so your settings remain in effect when you switch songs.
