It is easy to convert a mp3 to mp4 using python pydub. Here is the example code: from pydub import AudioSegment # assign files input_file = r"D:\1878_2.mp3" output_file = r"D:\1878_2.wav" # convert mp3 file to wav file sound = AudioSegment.from_mp3 (input_file) sound.export (output_file, format="wav") This example code will convert 1878_2.mp3 A WAV file can be prohibitively large in size – ten times larger than an MP3 file. This makes sharing and storing WAV files particularly challenging. If a WAV file has been converted to a compressed file format and then later converted back to a WAV file, then the original audio quality of that WAV file would have been lost. 5.

Once that is done, sox -h will list supported formats. When mp3 libraries are installed, sox -t wav -r 8000 -c 1 -t mp3 . Share. . WAV files are lossless compared to the lossy MP3 file format, meaning that WAV audio is a high-quality uncompressed file. This also means WAVs are typically larger in file size. It’s why MP3 audio is ideal for smaller devices and streaming, while the WAV format is excellent for studio recordings and audio mastering. WAV is an acceptable lossless format for most services. However, depending on the service, that file might be converted and compressed to a different format. MP3 files can be uploaded to all the popular streaming services, but there’s no reason to convert a lossless file format, such as WAV, to MP3 if you don’t have to.
