FFmpeg] How to Batch Trim MP3 Files Using FFmpeg on Windows

-

Introduction: Why Batch Trimming MP3s with FFmpeg Saves Time

If you only need to trim one or two MP3 files—like cutting out an intro or logo sound—online audio trimmers are good enough.
However, if you need to crop dozens or hundreds of MP3 files, using an online tool becomes extremely time-consuming.

That’s where FFmpeg, a free and open-source command-line tool for processing audio and video, comes in. It’s fast, efficient, and works on all major platforms.

Environment

  • OS: Windows 10 Pro x64
  • Tool: FFmpeg full build (version 2022-07-04)

FFmpeg Basics: How to Crop a Single MP3 File

Parameters explained:

  • -i: Input file path
  • -ss: Start time (can include milliseconds)
  • -t: Duration (in seconds)
  • -acodec copy: Copy audio codec (no re-encoding = faster)

Example 1: Trim from 10.123 seconds to end

ffmpeg -i input.mp3 -ss 00:00:10.123 -acodec copy output.mp3

Example 2: Trim from 5 seconds for 5 minutes

ffmpeg -i input.mp3 -ss 00:00:05 -t 300 -acodec copy output.mp3

Batch Processing: Automatically Trim Multiple MP3 Files

To batch crop MP3 files in a folder using FFmpeg on Windows 10, use the following batch script:

Script: batch_trim.bat

@echo off
for /R %cd% %%G in (*.mp3) do (
    ffmpeg.exe -i "%%G" -ss 00:00:04 -acodec copy "%%~nG_cut.mp3"
)

Script Breakdown:

  • for /R %cd% %%G in (*.mp3): Recursively loops through all MP3 files in the current directory
  • %%~nG: Gets the filename without the extension
  • Output files will be named as originalfilename_cut.mp3

✅ Tip: Place this script in the same folder as FFmpeg or ensure FFmpeg is added to your system PATH.

Final Thoughts

Batch trimming MP3s with FFmpeg is:

  • Faster than online tools
  • Customizable for any start time or duration
  • Free and open source

If you're regularly editing podcasts, intros, or background music, automating with FFmpeg will save you hours of manual work.

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running.
