Everything is so soft - and the slider option for fine tuning is great. It’s generated on the spot instead of a file being played back which is what most “generators” really are. The only Green noise app I can find that has such high quality and accurate noise generation. Comparing the tone to other soundscapes, the tone of the noises provided in this app are highly accurate to natural recordings while still being noise from a noise generator. Great stuff. Great to listen to, and soothing. The Green noise specifically reminds me exactly of wind in the mountains for our summer trips. Exactly the right tone. ## Frequently asked questions about Moss ### What sounds does Moss offer? Moss offers synthesized green noise for free.
