I converted 36 WAV files that range from 10 mins to 1 hour in length in "batch conversion" from 48000 to 44100, and all of them now have a horrible hiss. What happened? Can this be reversed??

I'm still having this issue. Recently I had to convert stereo wav files down to mono mp3 files, you can hear the "before and after" from two files I've posted here: WeTransfer

thoughts??

What other parameters did you have set for the conversion? Was it only the sample rate or did the conversion involve the bit depth as well? Can you show a screen grab of the Batch Process window export settings?

As to whether it can be undone depends on where and how you saved the output of the batch conversion using different file names (as would have happened by default) and still have all the 48kHz originals.

I'm pretty sure I did an "over write" of the originals (stupid, I now realize). Here's a screen shot - but the original sample rate was 48000, not 44100 as shown here

One of the easiest ways to stop overwriting of the original files is to set a Prefix or Postfix to automatically add to the file name. However the settings that you used there shouldn't have made the audio anymore 'hissy' unless you also had some effects applied in the Batch Processing pane. Can you post one of the noisy files via Dropbox or Google Drive for us to take a listen to?
