Introduction:
Editing MP3 tags with Python is a common task that can be done easily using the `mutagen` library. `mutagen` is a Python library for handling audio metadata. It supports a wide range of audio formats, including MP3, FLAC, OGG, and more.
Required pip:
Here's a step-by-step guide on how to edit MP3 tags using Python and `mutagen`:
1. Install the `mutagen` library using pip:
pip install mutagen
Steps to implementation:
2. Import the `mutagen` library and open the MP3 file:
from mutagen.mp3 import MP3
audio = MP3("filename.mp3")
3. Access the tags of the MP3 file:
audio_tags = audio.tags
4. Modify the tags as needed:
audio_tags["TIT2"] = "New Title"
audio_tags["TPE1"] = "New Artist"
audio_tags["TALB"] = "New Album"
In this example, we are modifying the title, artist, and album tags of the MP3 file.
5. Save the changes to the MP3 file:
audio.save()
This will save the modified tags to the MP3 file.
Demo Code:
Here's the complete code for editing MP3 tags with Python and `mutagen`:
audio = MP3("filename.mp3")
audio_tags = audio.tags
audio_tags["TIT2"] = "New Title"
audio_tags["TPE1"] = "New Artist"
audio_tags["TALB"] = "New Album"
audio.save()
Note that MP3 tags are stored in ID3 format, which is a metadata container format used in MP3 files. The tags are identified by a four-letter code, such as `TIT2` for title, `TPE1` for artist, and `TALB` for album. You can find a list of ID3 tag codes and their meanings online.
In addition to modifying tags, `mutagen` allows you to read and edit other metadata in MP3 files, such as bitrate, duration, and more. You can also use `mutagen` to handle other audio formats, such as FLAC, OGG, and more.
Change MP3 "Name" with Its "Title":
Suppose you have a list of MP3 files that are named using only numerical values, but their title tags contain the actual names of the MP3 files. You want to change the names of the MP3 files to match their title tags using batch renaming in a Python program.
Yes, you can use Python to rename your MP3 files based on their title tags.
from mutagen.mp3 import MP3
# set the path to your MP3 files
path = "/path/to/mp3/files"
# loop through each file in the path
for filename in os.listdir(path):
if filename.endswith(".mp3"):
# open the MP3 file and get the title tag
audio = MP3(os.path.join(path, filename))
title = audio.tags.get("TIT2", None)
if title:
# use the title as the new filename
new_filename = title[0] + ".mp3"
# rename the file
os.rename(os.path.join(path, filename), os.path.join(path, new_filename))
print(f"Renamed {filename} to {new_filename}")
This script uses the `os` module to loop through each file in the specified directory (`path`). For each file with a `.mp3` extension, it opens the file using `mutagen`, gets the title tag (if it exists), and uses the title as the new filename. Finally, it renames the file using `os.rename`.
Note that this script assumes that the title tag contains only valid characters for a filename. If your title tags contain characters that are not allowed in filenames (such as `/`, `\`, `:`, `*`, `?`, `"`, `<`, `>`, or `|`), you may need to modify the script to replace these characters with valid alternatives.
Change MP3 name with title with number:
Suppose you have a list of MP3 files that are named using only numerical values, but their title tags contain the actual names of the MP3 files. You want to change the names of the MP3 files to match their title tags using batch renaming in a Python program, while also including a natural number in the renamed text."
Sure, you can modify the script to include a natural number in the filename, in addition to the title tag. Here's an example modified script:
from mutagen.mp3 import MP3
# set the path to your MP3 files
path = "/path/to/mp3/files"
# initialize the counter
counter = 1
# loop through each file in the path
for filename in os.listdir(path):
if filename.endswith(".mp3"):
# open the MP3 file and get the title tag
audio = MP3(os.path.join(path, filename))
title = audio.tags.get("TIT2", None)
if title:
# use the title and counter as the new filename
new_filename = f"{counter:03d} - {title[0]}.mp3"
# rename the file
os.rename(os.path.join(path, filename), os.path.join(path, new_filename))
print(f"Renamed {filename} to {new_filename}")
# increment the counter
counter += 1
In this modified script, we add a `counter` variable that is initialized to 1 at the beginning of the script. For each MP3 file with a valid title tag, we use the `counter` and the title tag to create a new filename that includes the counter as a natural number in a three-digit format (e.g. `001`, `002`, `003`, etc.). We then rename the file using the new filename and increment the `counter` variable.
Note that the `:03d` in the `f"{counter:03d} - {title[0]}.mp3"` line is a format specifier that pads the `counter` variable with leading zeros to ensure that it has three digits. You can change the number of digits by modifying the `:03d` specifier accordingly.
