[파이썬] moviepy 오디오 잘라내기 및 병합하기

Moviepy is a powerful Python library that allows you to manipulate videos and audios. In this tutorial, we will learn how to cut and merge audio files using Moviepy.

Prerequisites

Before getting started, make sure you have Moviepy installed. You can install it using pip:

pip install moviepy

Cutting Audio

To cut an audio file using Moviepy, follow these steps:

  1. Import the necessary libraries:
from moviepy.editor import AudioFileClip
  1. Load the audio file:
audio = AudioFileClip("input_audio.mp3")
  1. Define the start and end times for the desired audio segment:
start_time = 10  # Start time in seconds
end_time = 30  # End time in seconds
  1. Extract the desired audio segment using the subclip method:
cut_audio = audio.subclip(start_time, end_time)
  1. Export the cut audio to a new file:
cut_audio.write_audiofile("output_audio.mp3")

You can replace "input_audio.mp3" and "output_audio.mp3" with the paths to your input and output audio files, respectively. Adjust the start_time and end_time values to specify the desired segment you want to cut.

Merging Audio

To merge multiple audio files into a single file, follow these steps:

  1. Import the necessary libraries:
from moviepy.editor import concatenate_audioclips
  1. Load the audio files:
audio1 = AudioFileClip("audio1.mp3")
audio2 = AudioFileClip("audio2.mp3")
audio3 = AudioFileClip("audio3.mp3")
  1. Concatenate the audio files using the concatenate_audioclips method:
merged_audio = concatenate_audioclips([audio1, audio2, audio3])
  1. Export the merged audio to a new file:
merged_audio.write_audiofile("merged_audio.mp3")

You can replace "audio1.mp3", "audio2.mp3", "audio3.mp3", and "merged_audio.mp3" with the paths to your input and output audio files, respectively. Adjust the list of audioclips to include all the audio files you want to merge.

Conclusion

In this tutorial, you learned how to cut and merge audio files using Moviepy in Python. Moviepy provides a simple and intuitive interface to perform these operations on audio files. By leveraging its capabilities, you can easily manipulate audio files according to your needs.

Happy coding!
