Create tags for your media files.
Define Start/End time and additional information for each media tag.
Later, you can play the tags using an embedded media player.
This tool really helps me to study guitar. I record my master teacher for a ~1 hour each lesson. Then I tag all the material adding meta information for each tag. Then I play every tag in the embedded player (& on guitar). This extremely accelerates my learning process!!! Thank you for such a useful tool :)
