FL Studio Mobile
Stereoizer creates stereo effects from mono sources. Use it to create a 'wider' sounding mix.
To load presets tap the menu icon (upper right) and choose Presets List.
There are two stereo effects available - Phase based - Strength, Timber and Focus OR Delay based ('Haas effect') - L/R Delay.
Delay stereoizing (Haas effect): Normally, to use this effecy, set Strength, Timbre and Focus to zero, so only L/R Delay is active.
