Title: Batch editing MP3 files
Post by: hollowman on 2008-11-01 04:26:02
I need to chop off the first few seconds of over 100 MP3 files. How can I do this quickly (batch edit ) with (preferably) freeware? I have Audacity, and also Nero's packaged audio editor.

Thx for an info you can provide!

I saw this application mpTrim, might just do the trick you're looking for.

Thx for your reply. The version of this program that will do what I want costs $70.00 (USD). A bit beyond what I want to pay.

I don't use Audacity, so I don't know if it will do exactly what you want, but it does have batch processing (http://audacityteam.org/manual/index.php?title=Batch_Processing) capability.

You might want to consider a special-purpose MP3 editor that can directly (losslessly) edit MP3s.  As you may already know, most audio editors have to decode the MP3 before editing and re-encode it before saving.  This takes time and it can affect audio quality.  A couple of lossless MP3 editors that I know of are mp3DirectCut (http://mpesch3.de1.cc/mp3dc.html) (FREE!!!) and MP3 Surgeon (http://www.mp3surgeon.com/sur_screen.php) ($30 USD).  MP3 Surgeon also has a "batch mode".  (I've never used either of these programs... I'm just aware of them...)

Didn't know about the Audacity Batch Preferences mode. Alas, it doesn't seem to have Batch Edit.
mp3DirectCut looks promising and I've contacted its developer to investigate options.

(BTW: The purpose of my batch-editing needs is to remove ubiquitous intros /endings to podcasts -- like a TV commercial skip)

Have you been able to find a batch editor you were looking for?

Save this as mp3split.cmd, and to crop first 5 sec run: mp3split.cmd 00:05:00 path-to-mp3s/*.mp3
Code: [Select]
for %%f in (%2) do (
    echo FILE "%%~f" MP3> sheet.cue
    echo TRACK 01 AUDIO>>sheet.cue
    echo INDEX 01 00:00:00>>sheet.cue
    echo TRACK 02 AUDIO>>sheet.cue
    echo INDEX 01 %1>>sheet.cue
    mp3directcut.exe sheet.cue /split
)
del sheet.cue


/edit: Its easier to do Cut from the gui, under batch processing menu.
