[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]
- Online streaming sources are not supported, unless pre-downloaded as local files.
- Items protected in the local Audio Library (e.g.: iTunes) are not supported.
- Acceptable audio file formats are: wav, flac, mp3, aac, m4a and ape, with standard stereo L/R channel layout, 44.1kHz ~ 192kHz, 16/24Bit.
- Preferred audio file location is the system designated "Music" folder, or otherwise explicit access permissions will be required repetitively.
- Common DJ features are not included
- Basic knowledge in analog tape recording would be required.
