A full version app for Android, by Suture Sound Inc..

Flip Sampler is a free mobile music app that was designed for a fast and intuitive workflow. Flip can record a song or multiple songs in performance and export the audio file(s) to your device. 16 sections can be created by dragging and dropping them into your recording. 

As Flip Sampler has high CPU usage, your device must be Android 10 and up to ensure a smoother experience. 

A note about audio:

If you have an Android phone or tablet that is capable of recording audio, Flip will record the sound from the microphone. It is recommended that you use the default microphone on your device.
