Tinnitus Masker is hardware you can download (there's a free trial so you can try before buying). It's supposed to help mask your tinnitus by allowing you to mix sounds together to create either real time or recorded masking relief. The theory here is that as each person's tinnitus is unique, pre-recorded masking sounds simply cannot be adjusted minutely enough to perfectly suit the individual user. But by adjusting the output of each sound exactly to your specific requirements, you'll hopefully be able to create a masking effect that works for you and which can be adjusted (if need be) over time as your tinnitus changes. Disclaimer: I haven't tried this product nor am I an affiliate. I just thought it looked promising. If you've tried this or any other masking device, please leave a comment as to whether or not it was of any help. Try Quietum Plus
