The Ambient Environments soundscapes are quality recordings that combine sound and music into an audio atmosphere for your storytelling games. Each track is ten minutes long, with no fade in/out at the start or end, making them perfect for continuous looping. While reviewing this series, I played each track in the background and often didn't notice when it had started over. The sound levels are compressed very well, which means that there will be very few distracting volume changes when you play these during a session. And at $1.49 each, the price is very reasonable.
The Dungeon Crawling soundscape features ambient music, a torch cracking and whooshing as it is moved around, water dripping, rats squeaking, distant growls and other "possible monster" noises. The "torch whooshes" can get a bit repetitive and distracting in this one, but otherwise the track works very well.
