python check audio file type, MP3 or FLAC

问题

I want to check if a audio file to see if its MP3 or FLAC the checks only have to be basic but I want to go beyond simply checking the file extensions

os.path.splitext

Works okay but no good if the file doesn't have an extensions written in or someone passes a file with a fake extension

I've tried but it just returns None

sndhdr.what(file)

I've also tried using magic but it returns 'application/octet-stream' which isn't much use.

magic.from_file(file, mime=True)

I've read Mutagen could be good for this but so far failed to find any function that outputs the audio encoding as MP3 or FLAC

To find the File format including audio, video, txt and more, you can use fleep python library to check the audio file format:

First you need to install the library:

pip install fleep

Here is a test code:

import fleep

with open("vida.flac", "rb") as file:
    info = fleep.get(file.read(128))

print(info.type)
print(info.extension)
print(info.mime) 

Here is the results:

['audio']
['flac']
['audio/flac']

Even if the file doesn't have an extension or someone passes a file with a fake extension, it will detect and return.

Here I have copied the vida.wav file to dar.txt and also removed the extension

import fleep

with open("dar", "rb") as file:
    info = fleep.get(file.read(128))

print(info.type)
print(info.extension) 
print(info.mime) 

The result is still the same.

['audio']
['flac']
['audio/flac']

You can read file specifications of mp3 and flac and then can implement a checker that reads and parses mp3 as a binary file.A modifiable example with a similar goal is here
