Archive.org, which houses LibriVox files for downloads, keeps track of that activity for us. It's been habit for me occasionally to query for all of my solos (currently, 67 books - there are others that appear if you search, but they're single-file works, which I don't count.) That's a fair amount of work to sleuth out and tot up!
In February I counted up, figured out the download rate for each book, year-to-date, and did a projection: if things held steady, then on or by August 15 (today) I should hit a cumulative total of ten million downloads! That's a big milestone!
Coincidentally, I just happened to think about checking today - I hadn't marked it on a calendar or anything, but if I'm going to devote the work to checking numbers, I usually pick mid-month.
I am delighted by the total! It stands at 10,277,638! Apparently I passed the marker about a month ago. My first solo published in March, 2006, so this represents about nine years of narration.
I thank LibriVox users again for investing so much time in listening to my voice. Special thanks to those who have dropped me notes on "Thank-a-Narrator" at the LibriVox site. My friend Carolin (who gets around but is currently living in The Netherlands), who is a LibriVox administrator, makes sure I see every one. And as I've noted before, it's listener feedback that keeps us narrators at our mics!
