我想在 linux 中使用 SOX 混合音频。这是我的脚本。我是这件事的初学者。

    time sox --buffer 128000 --combine mix audio1.mp3 audio_recorded.wav -C 64.0 "./Mixed.mp3"
    time ffmpeg -loglevel warning -i ./Output.wav -c:a libfdk_aac -b:a 64k -map 0:0 -f segment -segment_time 10 -segment_list ./Output.m3u8 -segment_format aac './stream%03d.aac'

    cd ..

但结果是这样的..

    sox FAIL formats: can't open input file `audio_recorded.wav': WAVE: RIFF header not found

    real    0m0.003s
    user    0m0.000s
    sys     0m0.002s

这audio_recorded.wav是从android录制的音频文件。

[删除安卓代码：不再需要]

更新：我试图修改我的录音机..设置比特率和采样率与 audio1.mp3 相同。然后我试着混合它。这就是现在发生的事情：

我设置了录制的采样率和比特率，因为当我尝试在 sox 中混合它时，它提示我文件没有相同的通道和比特率。

可能该文件没有标题。您可以指定文件类型

-t <file-type>

这是手册页： http ://sox.sourceforge.net/sox.html
