WavePad Music and Audio Editor

This is the fastest app I’ve found on the App Store to increase the length of all my silences in a recording. It’s almost like having audacity on an iPhone. But I do have to scroll through my entire audio, select each silence manually, and click “add silence at selection”, and click ok. And here’s why:
1) The advanced silence trimmer can detect silences, and even baits you with the option of “new silence length”, but it won’t actually add silence, it only wants to trim, as said in the user guide manual (haha which means the devs knew I might like to do this, and decided not to let me, lol).
2) The split/(batch)join would probably be able to do it, except the devs didn’t give us the option to import multiple files at once! You actually have to click “add files(s)…” again and again, once for every single file, and scroll down every time to find the next file. You can’t checkmark multiple files for import. So it takes so long to add all the files, that there’s hardly any benefit.
3) There seems to be no system to add marks throughout the file, and then apply actions at all the marked locations. For example, every feature that automatically detects any points in an audio, could (should?) give the option to mark all those detected points. So then you could automatically apply actions at all marked locations. For example, “trim silences: mark all”, and then “add silence: at every mark”.
