Download audio in a quality as high as 320 kbps. YTMP3.ch; YTMP3 YT to MP3 Converter is one of the prime options to convert YouTube to MP3 or even MP4 with ease. The software lets you convert your YouTube to MP3 with ease. I guess it's possible, but I wouldn't expect a huge difference. I just tried it on a lossless file, and the 320 Kbps AAC version was actually .9% larger than the 320 Kbps MP3.

Click the "Choose Files" button to select multiple files on your computer or click the "URL" button to choose an online file from URL, Google Drive or Dropbox.

You can use file analyzer to get source audio's detailed information such as track name Convert one track first to set up the mp3 quality. File > Import > Audio > choose your track. File > Export > Export as mp3. I get best results with: Bit Rate Mode - Variable Quality - 220-260 kbps (it will go higher than 260 if needed) Variable Speed - Fast. Channel Mode - Stereo.
