In the first post I noticed one typo (so far). Red emphasis mine:
The file name is missing an 'e' before "_01_chekhov". I believe it ought to be 'chelovekvfutliare_01_chekhov_128kb'....
Notes for the Editor:
Please name final edited chapters with the following format: chelovekvfutliar_01_chekhov_128kb.mp3 (Dramatis Personae will be numbered as "00".)
There should be ~5 seconds silence at the end of the recording.
