Ok. I correct. It does not need to be distorted progressbar but I need to have hotspots ( note or speaker sign) a after clicking to start playing the sound with proggres bar to see the time, length and play/pause button.
Imagine room with a lot af statues and each of them has the audio hotspot. Yes, it is enough to start and stop but it would be nice to have to each audio the proggres bar.
