About A/B Audio Player Pro
Let visitors hear the difference.
Press play, then switch between Before and After. The new version takes over at the exact same moment in the track. No gap, no restart, no click. Compare up to 6 versions in one player: Raw, Mix, Master, Reference.
Fair comparisons, built in
Louder always sounds "better". The player measures each version's loudness (LUFS) and level-matches them automatically, so visitors judge the sound, not the volume.
