Youtube is the biggest library of online video however it can also be a great source of audio as well. Sadly, Youtube does not allow viewers to download video or audio from its website. On computers there are several unofficial tools available that enable users to download the audio from their favorite videos. Just like the Youtube website, the official Youtube app for iOS does not allow users to download the audio on their devices. So there’s no way you can download video or audio from Youtube on your iPhone or iPad. That’s only true if you are not jailbroken as for the rest us a Cydia app called YoutubeToMp3, which makes this possible.
With YoutubeToMP3 you can convert any Youtube’s video into MP3 format and download them on your iOS device. The best thing about this Cydia app is that you don’t need your computer at any point. After getting the MP3 versions of your favorite video you can either listen to through this app’s built-in audio player, which also lets you create playlists or export that audio file to your device’s Music app. From the ‘All Songs’ page you can also delete, rename and share files you have downloaded using the application through email.
YoutubeToMp3 is not a new app as it has been available on the iOS platform since iOS 6. It recently got updated with full support for iOS 7. It works on all iOS devices including iPhone, iPad and iPod touch. You can get it for free from the BigBoss repo.
