// How to get resources file path:
- Using an audio player you can:
- Play sounds of any duration
- Play sounds from files or memory buffers
- Loop sounds
- Play multiple sounds simultaneously, one sound per audio player, with precise synchronization
- Control relative playback level, stereo positioning, and playback rate for each sound you are playing
- Seek to a particular point in a sound file, which supports such application features as fast forward and rewind
- Obtain data you can use for playback-level metering
