個人用了 mp3 隨身聽一段時間，都是用它來聽 StudioClassroom ，覺得很不錯。
不過總覺得每次都要聽它前面一段約 40 秒的音樂，覺得很不愉快，因為就是我要趕緊聽它的正文。
因為有時會使用電腦聽，mplayer, vlc 這類的軟體都能夠利用一個指令就自動略過每個 mp3 的前 n 秒。問題是如果是用mp3隨身聽的話，就沒有辦法這樣做了。除非直接對mp3剪接，目前都是利用 audition來做，但是總覺得很累。
有沒有方法或軟體能夠利用下指令的方式，直接剪掉 mp3 的前 40 秒？ Thank you.

剛才稍微試了一下 Goldwave 的下載試用版，它果然能夠從指令去批次編輯 mp3，雖然要另外「事先」設 preset 比較不方便一點，不能直接從指令就表示出要做什麼事。不過這樣已經是非常強了，是可以解決問題的軟體。
也試了 Audacity 1.3.2，不過它好像不能直接從指令去批次編輯檔案。雖然它的網頁上有宣稱到Improved batch processing，preferences>batch 的設定處有功能選項，但是到目前還找到不該如何用它。這可能還要再 try 一下。
sound forge好像要錢，所以就沒有試了。

Command line options
Usage: mp3DirectCut.exe <filename> <option(s)> <destination>
As <filename> every file type known by mp3DirectCut is possible (MP3, MP2, Project files, Cue sheets). Usually this is for the file to be opened. In your operating system settings you can associate mp3DirectCut to one or more of these file types and with different options. Then you can open the program easily by any file of that type. It is also possible to drag files of known types over mp3DirectCut.
If you use the <filename> parameter together with /rec you can set an individual record filename that differs from the base filename of the recording settings.
The following options can be used to let the program perform an action immediately. After finnishing, the program quits. Note that special adjustments (e.g. for Normalize, Auto cue, Encoder settings) cannot be given over the command line. They must be done before in the normal program environment.
Examples
mp3DirectCut track01.mp3 /normalize /overwrite
mp3DirectCut audiobook.mp3 /autocue d:\split
mp3DirectCut /rec
mp3DirectCut other_recname.mp3 /rec
Options
/normalize Normalizes the file up to 0 dB. Higher or lower levels cannot be set in the command line.
/autocue Splits the given file into segments of that length set in the Auto cue feature. For the performed Auto cue and Save split operations, the current settings available on normal program usage are applied. If as <destination> an existing folder is set, the split files will be saved there.
/pausesplit Runs the pause detector and splits the given file at all found pause positions. For the performed Pause detection and Save split operations, the current settings are applied. You can change them by normal program usage. As <destination> a folder for the split files can be set which must exist.
/save Opens and saves the file. Simple re-save can be used to eliminate incomplete frames or unwanted headers
/overwrite Replaces the original file. The "Keep date of source file" option is valid (it can be set in the program environment). If /overwrite is not set, the given file extension will be appended once more.
/rec Starts recording immediately. This feature is especially made for timer recordings. In a scheduler usually you can also set a duration time after which the program will be terminated. For multiple timer recordings be sure to check 'Add date and time' or 'Append data' in the recording settings, otherwise previous recordings will be overwritten. If a filename is given before the /rec option and 'Add date and time' or 'Append data' is not (!) selected, the program records into a file of that name.
