SnoreLog: a night summary scoring 67 with 2h 13m of snoring, beside a minute of audio where eleven snores are accepted on their 3.4-second rhythm and a door, television, cough and a partner turning over are rejected

SnoreLog

I wanted to know how badly I snore. A recorded night turns out to be full of other noise, and pulling the snoring back out of it was the whole problem.

Label

I write notes as I read, but stopping at every line to type breaks the thread of the book. Now underlining collects the passage and the note is already going.
