Some issues

Hi,

some moments:
1. f.e. mp3 files size may exceed the processing volume, so may be its better to save as intermediate result.
2. such string python main.py "C:\AB" "C:\AB\m4b\Protivost.m4b" "*.mp3" raises error of uknown parameter "*.mp3"
3. also in requiurements didnt find this module "audioop-lts".
