我正在混合两个 wav 音频文件，如下所示
/data/data/com.example.letsjam/app_bin/ffmpeg -i /storage/emulated/0/test1.wav -i /storage/emulated/0/test2.wav -filter:v amerge=inputs=2 /storage/emulated/0/output.wav
输出的 wav 文件仅包含第一个音频的声音。两个音频文件具有相同的采样率和相同的通道数，当然还有相同的格式，即 wav。以下是上述命令的 shell 输出：
shellLine: Input #0, wav, from '/storage/emulated/0/test1.wav':
shellLine: Metadata:
shellLine: encoder : Lavf55.42.100
shellLine: Duration: 00:00:05.02, bitrate: 2048 kb/s

我做错了什么吗？我也试过了，amix但结果是一样的。生成的输出只有第一个音频文件的声音。任何帮助都将不胜感激！

您尝试过使用吗audacity？您可以同步多条音频线路，然后可以混合并导出它们。请参阅此手动输入。
