Best way to rip audio from Youtube? (not for the reason you think!!)

[Tortango]

I have an odd problem today... someone asked me for an mp3 download of a mix that I put on youtube some time ago, but I no longer have the audio recording saved anywhere. I would like to make the highest quality possible rip of my own youtube video and then upload that audio to soundcloud... anyone know a way to do this?

I have seen "youtube to mp3" websites before, but without the advice of someone who knows more about this I don't trust any of them to give me good audio quality.

Use DownloadHelper or equivalent to download the original Youtube MP4 file (in HD 720p+ if possible). Then demux the file to get the audio separated.

There's also a Chrome add-on that you download that will allow you to download with 1-click straight to .mp3.

Converting to MP3 is an unneccesary step though. The audio can be extracted without conversion from the video, and decompressed to WAV/AIFF if needed for Soundcloud.

Thanks guys! Any recommended software for demux?

MP4Box GUI is free and easy to use:

Ripped the audio, hosted it on soundcloud with downloads enabled, and the person who requested the download was very grateful. Thanks for the help, that was easier than I expected.

The Media-Human Youtube to MP3 Converter is very good too. You can download music from Youtube at HQ (i think, at least the ones which are HQ), and you can also download entire playlists just by choosing one of the musics on it

vidmate application has the function of extracting audio from youtube video. Have you tried vidmate?

Log in, go to creator studio, click on video manager, on the dropdown next to edit choose Download MP4.

Now simply convert the MP4 to .wav or MP3. You can also pull the audio in most video editors such as Premiere.
