## What is MusicFreq?

MusicFreq is a music player.

MusicFreq analyzes the audio data of the DRM Free music being played and visualizes it in a real-time frequency spectrum graph.

This graph appears when you're playing DRM-free (unprotected) MP3, M4A, AIFF, etc. music files that have been synced to your Music Library using your Mac or Windows computer and then downloaded to your device.

Music purchased from AppleMusic or iTunesStore is in m4p (AAC) format protected by DRM (Apple FairPlay). Please note that protected audio files and cloud items will not be displayed in the graph. (Music can still be played.)

Graphs can be customized as line, scatter, and bar graphs.
The screen color changes to the same color as the album artwork of the music being played.
You can control music with tap, long tap, left and right swipe.
Display the simplified setting menu with the upper swipe.
You can quickly change the basic color of the screen to your favorite color with few operations.
Screen rotation is automatic and can be displayed and operated in both portrait and landscape.

MusicFreq controls the iOS system player, so the music to be played is shared with the music library of the iOS Music App, the music controller widget in the lock screen and the control center, the equalizer for the music in the settings app. You can also use the timer stop setting within the settings app to stop playback.
It is also possible to remotely control the player from a Blutooth device.

Preparation

Add DRM-free music files such as MP3 and M4A (unprotected AAC) to the Music app library on your Mac or Windows computer.
Connect your iPhone to your Mac or Windows computer and sync your music library.
Download the synced DRM-free music in the Music app on your iPhone and start playing it.
Make sure the graph is displayed in the MusicFreq App.

Notes

All audio files in the music library can be played, but only DRM-free (unprotected) music files such as mp3 and m4a can be displayed as a graph.
Also, cloud items cannot be analyzed on the device and will not be displayed in graphs, so please download them to the device using a genuine iOS music app.
You cannot add DRM-free music files to your library on only device such as an iPhone iPad or iPod Touch.
You need a Mac or Windows Computer to load DRM-free (unprotected) music files such as mp3s and m4a into your iOS Music App library.

Graph drawing is a heavy processing load, which can cause your device to overheat and consume more power. Please be careful of your battery level.
