Decreasing audibility, so not as pleasurable as before.
I have done freelance transcription with Rev.com for years. Sadly, I've found the audio files available to claim are decreasing in audibility over the last few months, despite the fact that I've downloaded various audio apps to enhance clarity etc, so income has decreased substantially. I used to think that low reviews mentioning difficulty etc were odd, but after getting knocked down from Rev+ status myself by a single harsh grading, I understand.
