I was testing imitone a bit watching for CPU usage, seems it is quite better that 0.8 in that aspect, nice.
But in Process Explorer (oh yeah, I'm on Windows 10 64bit) I'm also seeing a constantly rising memory usage. Slow but steady.
I'll look into this. imitone uses so little memory that tracking down leaks has tended to be a lower priority — but not the sort of thing I should let slip by. Let me know if you see significant (>300MB) memory usage.
