Manipulating multiple audio files with PyDub
You've seen how to convert a single file using PyDub
but what if you had a folder with multiple different file types?
For this exercise, we've setup a folder
which has .mp3
, .m4a
and .aac
versions of the good-afternoon
audio file.
We'll use PyDub
to open each of the files and export them as .wav
format so they're compatible with speech recognition APIs.
This exercise is part of the course
Spoken Language Processing in Python
Exercise instructions
- Pass
audio_file
to thefrom_file()
function. - Use
export()
to exportwav_filename
with the format".wav"
.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Loop through the files in the folder
for audio_file in folder:
# Create the new .wav filename
wav_filename = os.path.splitext(os.path.basename(audio_file))[0] + ".wav"
# Read audio_file and export it in wav format
AudioSegment.from_file(____).____(out_f=wav_filename,
format=____)
print(f"Creating {wav_filename}...")
