I listened and indeed there is some persistent squealing, sounds like the results of enthusiastic noisecleaning to me....Dear Librivox,
I am sorry to bother you with this complaint. I have been listening to "The Tenant of Wildfell Hall." There are several chapters that have a very audible BEEP BEEP BEEP going on in the background of the recording throughout the whole chapter. Sometimes it is quiet enough to almost (but not quite) ignore, but after chapter 25 I had to give up. 26 is equally bad. It is headache material! I am sorry to complain. I love your service!! I don't remember which of the earlier chapters were beeping because I thought I could just ignore it, or I'd tell you those, too. The voice recording is wonderful; it's just this background beep. I tried listening to a different version of the chapter (e.g., the 7.7mg version versus the 3.3mg) but they were the same.
Not sure if there is anything to be done ....
