ios – Create trimming UI like build-in iPhone Voice Memo App in swift

I’ve the identical problem like Audio cutter native iOS aspect , iOS voice recorder visualization on swift , Crop Audio Recordsdata however no solutions have but been posted on these matters. Furthermore I’ve Googled it rather a lot principally libraries associated to movies trimming not for audio or developed in objective-C.

I need to create audio recording App. On this App I need to implement trim and lower performance however I’m caught on UI half.

1. The way to create waves when audio report based on voice?
2. The way to reveals waves which is already recorded audio and its scrolling when audio performs?
3. The way to create UI for lower want audio like yellow? Similar as iPhone Voice Memo App.

Can anybody please information me that How I can obtain above functionalities?

Thanks prematurely
