VLC says that my recorded wav file has a duration of 1:14:09, but when it reaches 40:57 it stops abruptly. Other programs like Audacity and Media Player say the duration is 40:57. However, the audio ends at a point where it is not supposed to end, I don't think I stopped the recorder at that point. From the contents of the recording it does look like there might be about 20-30 minutes of audio missing at the end. I'd like to know what's going on with this file, specially if those 23 minutes of missing audio are somewhere inside the file and it is possible to recover them.
