我正在使用mp3gain。目标是将文件规范化为98db并接受剪切。我的命令是
mp3gain.exe /r /d 98 /c /p music.mp3
但是它已经失真了。使用归一化文件到98db并在GUI中接受剪切是有效的。
如何更改命令？
这是mp3gain.exe的输出
Usage: mp3gain.exe [options] <infile> [<infile 2> ...]
options:
/v - show version number
/g <i> - apply gain i to mp3 without doing any analysis
/l 0 <i> - apply gain i to channel 0 (left channel) of mp3
without doing any analysis (ONLY works for STEREO mp3s,
not Joint Stereo mp3s)
/l 1 <i> - apply gain i to channel 1 (right channel) of mp3
/r - apply Track gain automatically (all files set to equal loudness)
/k - automatically lower Track/Album gain to not clip audio
/a - apply Album gain automatically (files are all from the same
album: a single gain change is applied to all files, so
their loudness relative to each other remains unchanged,
but the average album loudness is normalized)
/m <i> - modify suggested MP3 gain by integer i
/d <n> - modify suggested dB gain by floating-point n
/c - ignore clipping warning when applying gain
/o - output is a database-friendly tab-delimited list
/t - mp3gain writes modified mp3 to temp file, then deletes original
instead of modifying bytes in original file
/q - Quiet mode: no status messages
/p - Preserve original file timestamp
/x - Only find max. amplitude of mp3
/f - Force mp3gain to assume input file is an MPEG 2 Layer III file
(i.e. don't check for mis-named Layer I or Layer II files)
/? or /h - show this message
/s c - only check stored tag info (no other processing)
/s d - delete stored tag info (no other processing)
/s s - skip (ignore) stored tag info (do not read or write tags)
/s r - force re-calculation (do not read tag info)
/u - undo changes made by mp3gain (based on stored tag info)
/w - "wrap" gain change if gain+change > 255 or gain+change < 0
(use "/? wrap" switch for a complete explanation)
If you specify /r and /a, only the second one will work
If you do not specify /c, the program will stop and ask before
applying gain change to a file that might clip
