HOW TO TRIM MP3 FILES USING PYTHON

Audio editing can often seem complex, but with Python, it becomes straightforward and efficient. Whether you want to cut out unwanted parts of a podcast or shorten a music file for a project, trimming MP3 files using Python is a skill worth learning.

Getting started

First, you’ll need to install “pydub”.You can do this using pip:

pip install pydub

Additionally, ‘pydub’ relies on the ‘ffmpeg’ library to handle various audio formats. Ensure you have ‘ffmpeg’ installed on your system. You can download it from ffmpeg.org and follow the installation instructions for your operating system.

TRIMMING AN MP3 FILE

STEPS:

STEP 1:IMPORT LIBRARIES

from pydub import AudioSegment

STEP 2:LOAD THE MP3 FILE

Load the mp3 file into an ‘AudioSegment’ object.

audio = AudioSegment.from_mp3("path_to_your_file.mp3")

STEP 3:DEFINE THE TRIM POINTS

Define the start and end points for the trim

start_time = 30 * 1000 # 30 seconds
end_time = 90 * 1000   # 90 seconds

STEP 4:TRIM THE AUDIO

Use the slice notation to trim the audio:

rimmed_audio = audio[start_time:end_time]

STEP 5:EXPORT THE  TRIMMED AUDIO

trimmed_audio.export("trimmed_file.mp3", format="mp3")

FULL CODE

from pydub import AudioSegment

# Load the MP3 file
audio = AudioSegment.from_mp3(“path_to_your_file.mp3”)

# Define the start and end times in milliseconds
start_time = 30 * 1000 # 30 seconds
end_time = 90 * 1000 # 90 seconds

# Trim the audio
trimmed_audio = audio[start_time:end_time]

# Export the trimmed audio
trimmed_audio.export(“trimmed_file.mp3″, format=”mp3”)
