如何使用 sox 删除元数据或者防止添加评论“由 SoX 处理”？

如果使用 sox 进行转换，它会在元数据中添加一条注释：

$ soxi audio.wav

Input File     : 'audio.wav'
Channels       : 1
Sample Rate    : 48000
Precision      : 24-bit
Duration       : 00:00:04.20 = 201600 samples ~ 315 CDDA sectors
File Size      : 605k
Bit Rate       : 1.15M
Sample Encoding: 24-bit Signed Integer PCM

$ sox audio.wav audio.flac
$ soxi audio.flac

Input File     : 'audio.flac'
Channels       : 1
Sample Rate    : 48000
Precision      : 24-bit
Duration       : 00:00:04.20 = 201600 samples ~ 315 CDDA sectors
File Size      : 414k
Bit Rate       : 788k
Sample Encoding: 24-bit FLAC
Comment        : 'Comment=Processed by SoX'

如何预防或者消除这种情况？
