 This player has two modes, SOUND_MODE_AUDIO which uses the audio element to load sounds via the audio element and SOUND_MODE_FETCH to load sounds via the web audio API. Here are some of the differences between the two:
 
-### the web audio API
+### the web audio API (SOUND_MODE_FETCH)
 
 * No support for streaming
 * Files get loaded using fetch, the loading progress is in percent and it is a single value between 0 and 100 percent loaded
 * A song has to be fully fetched before it can be turned into a buffer and hence before the playback can start
 
 For a more complete list of features, check out the w3c [web audio API features list](https://www.w3.org/TR/webaudio/#Features) in their [candidate recommendation document](https://www.w3.org/TR/webaudio/#Features)
 
-### the audio element
+### the audio element (SOUND_MODE_AUDIO)
 
 * Support for streaming
 * Files get loaded using the audio element, the loading progress is not just a single value, it can be split into multiple parts (time ranges), so for example the start of a song from 0 to 10 percent got loaded, then there is a blank of not yet loaded data and then also the part from 35 to 60 percent has been loaded
