[Note]
To use this app to its full potential, basic understanding of analog tape recording would be highly beneficial, e.g.: terms like “dB”, "VU", "MOL" and "SNR”... The app’s core functionalities are designed around these concepts. The app comes with documentation, wizard, and online videos to ease the learning curve. Once you’ve picked up the new workflow, it will become effortless. But please be aware before acquiring the app.

[Limitations]
