1. Instrumental/Karaoke practice
PracTone supports the following functions for performance parts / karaoke practice.

(1) AB loop

Using the AB loop function, you can practice a specific playback section repeatedly. This is useful if you want to focus on difficult sections or sections where you are likely to make mistakes when practicing a performance part.
An unlimited number of settings can be saved for each song.
This feature is also available for Apple Music/DRM/iCloud songs.

(2) Time Stretch and Pitch Shift

You can slow down the playback speed when practicing or playing by ear, or speed it up as you improve. You can also practice by adjusting the pitch of the sound source without changing the tuning of the stringed instrument. You can use it in various ways, such as lowering the pitch when practicing vocals.
Also, the playback speed change function can be used with Apple Music/DRM/iCloud songs.(premium version)

(3) Separator (sound source separation)

You can adjust the volume balance of the sound source (song) to vocals, drums, bass, and other performance parts as you like. An unlimited number of settings can be saved.
As an example of use, when playing by ear, cut/lower the volume other than the target volume. When practicing jointly with a sound source, please cut/make your playing part smaller.
There is no need to connect to the Internet for sound source separation. Also, since it works like real time, no storage saving is required for this feature.
[2 Stems (Vocals/Others) / 4 Stems (Vocals/Drums/Bass/Others) *premium version]

(4) Equalizer

You can adjust the sound quality to your liking by increasing or decreasing the volume for each frequency band. An unlimited number of settings can be saved.
