尝试使用 sox 或 ffmpeg 将双声道声音文件转换为单声道时出错

Question

当我尝试时：

sox file.wav -c 1 file.wav

我有：

sox WARN wav: Premature EOF on .wav input file

当我尝试时：

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

我有：

[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

Answer 1

问题在于使用同一个文件作为输入和输出。
