Note before you begin: Importing from the Music app on your device is the slowest and least reliable method to import tracks. Importing from the Music app requires Soundboard Studio to completely re-encode the audio file, since 3rd party apps are restricted from copying the original file. This means imports are much slower for all tracks and can occasionally result in tracks failing to import or endlessly loading forever. If you have very long audio files, these issues may occur.
Recommended Alternative: Move your audio files to the Files app on your device, or onto a file sharing service such a Google Drive, Dropbox, or iCloud Drive. Importing from these locations will be 100% reliable and do not require re-encoding, so importing is instant.
