音頻一批修剪開頭和結尾使用紅襪

Question

如何合併兩個，所以多個文件進行處理，每個文件修剪從開始15秒，15秒底：

@echo off 
cd E:\trim\multiplefiles 
mkdir trimmed 

rem trims 15 seconds from end of each file, and creates a snipped file in 
rem trimmed folder 

FOR %%A IN (*.wav) DO sox "%%A" "trimmed\%%~nxA" reverse trim 15 reverse 

和

@echo off 
cd E:\trim\multiplefiles 
mkdir trimmed 

rem trims 15 seconds from beginning of each file, and creates a snipped file in rem trimmed folder 

FOR %%A IN (*.wav) DO sox "%%A" "trimmed\%%~nxA" trim 15 

Answer 1

紅襪修剪效果可以讓你同時指定開始和持續時間，以及負的持續時間規定了從底了測量的終點文件。因此sox infile outfile trim 15 -15將從文件中移除前15秒和後15秒。

@echo off 
cd E:\trim\multiplefiles 
mkdir trimmed 

rem trims 15 seconds from beginning and end of each file, putting result in trimmed folder 

FOR %%A IN (*.wav) DO sox "%%A" "trimmed\%%A" trim 15 -15 

注意~nx不需要在輸出規範。

Answer 2

我會假設您可以先從文件末尾修剪15秒，然後從結果開始修剪15秒。然後，你可以把一切都放在一個循環，並使用臨時文件是這樣的：

@echo off 

cd E:\trim\multiplefiles 
mkdir trimmed 

FOR %%A IN (*.wav) DO (
    rem trim 15 seconds from end and put it in temporary file 
    sox "%%A" "trimmed\temp_%%~nxA" reverse trim 15 reverse 
    rem trim 15 seconds from beginning of the temporary file 
    sox "trimmed\temp_%%~nxA" "trimmed\%%~nxA" trim 15 
    rem delete temporary file 
    del "trimmed\temp_%%~nxA" 
)
