BlackSave Alternative: Black Duck Media Library

BlackSave main screen with video playback — **BlackSave** is better if you mainly want to split audio out of a video already on your phone.

Black Duck Media Library is better if you want saved media kept in one library.

BlackSave is a tool for extracting, saving, and sharing audio from a video that is already on your phone. Its listing describes background playback, splitting or extracting audio, and one-tap sharing. Its listing does not claim to download videos from social apps.

If you are looking for a replacement for BlackSave, Black Duck Media Library is one option to consider. It can save videos from social apps, and the downloaded file goes into a library next to your other media, including audio, so the audio part works in the same place.
