At9tool.exe [upd]

: For users who prefer a graphical interface, a tool called ATRACTool-Reloaded is available. This open-source GUI application is specifically designed to make at3tool.exe and at9tool.exe intuitive to operate, handling conversions without the need for command-line knowledge.

: Open your source audio in a tool like Audacity and export it strictly as a 16-bit Linear PCM WAV file. Ensure it matches the sampling rate expected by your command line flags (usually 44.1kHz or 48kHz) and check that it is saved as a Stereo track if encoding at high bitrates. 2.
