Error when trying to convert 2-channels sound file to mono using sox or ffmpeg

2

When I tried:

sox file.wav -c 1 file.wav

I got:

sox WARN wav: Premature EOF on .wav input file

When I tried:

ffmpeg -i file.wav -ac 1 file.wav

I got:

[pcm_s16le @ 0x2997880] Invalid PCM packet, data has size 2 but at least a size of 4 was expected
Error while decoding stream #0:0: Invalid data found when processing input

The problem was in using the same file as input and output.
