Put 2 files (1.mp3,2.mp3) in the same directory as the script files.
With small files (duration time ~ 1:30) there is no error. But with large files (duration time ~ 60 minutes there is sound error).
Try to run run_me.py
First click the first button, and after 5 seconds click the second.
Can you help me to solve this?
Edit: Code updated (added record feature with wave module)
Thanks in advance, Chris Pappas
