How do I separate bass with RePAN plugin?

RePAN separates a stereo mix into a number of different spatial bands. If bass is the only source present in a given spatial band then you can separate bass using RePAN. This sometimes occurs in older stereo mixes, but in most modern mixes, there are typically other instruments in the same spatial position as the bass. These will also be separated with the bass.

Regardless of the target use case, the first step in using RePAN is always to carefully listen to the mixed music and analyse how the mixing process positioned each source in space. A good rule of thumb is to always apply RePAN on the simplest mix available. For example it will be easier to extract a bass from a track without vocals and drums than from the full mix, therefore it will help to remove some other sources from the mix prior to using RePAN (with stem separation tools such as AudioSourceRE’s other plugins VOXLESS and DRUMLESS).
