EqualizeMusic vs EZ Set EQ

This app is the minimal version of a player with a 10-band equalizer. For reasons of simplification, it only contains the functions that are absolutely necessary for the player and equalizer. 
 With the app you can
 ・ create playlists from the music files stored on the device or in cloud storage. The tracks are saved in the sandbox and can therefore also be played offline. To use a specific cloud storage, the corresponding app must be activated. ・ define individual equalizer settings for the individual tracks. 
 ・ make a default setting for the individual playlists.
 ・ use a switch to determine whether the playlists are played with the individual EQ settings of the tracks or with the playlist preset.

Loudspeakers and room interaction inevitably introduce unwanted coloration to sound during playback – colorations which are sometimes either difficult or impossible to remove with traditional electronics or room treatments. The free EZ Set EQ app provides easy-to-use room equalization for optimized sound quality. The built-in microphone of a supported iOS device can be used for the calibration. Compatible with all models of JBL MA series AV Receivers. Note: For the best experience, please check your AVR is running the latest firmware.
