There are three main workflow modes: ONLINE, OFFLINE ENCODE and OFFLINE
DECODE. The modes are accessible via tabs at the top of the main graphical user interface
(GUI):
By default, the ONLINE mode is active, and the centre panel of the GUI provides a large
FFT (Fast Fourier Transfer) display, showing the spectral content of the input signal in
yellow, the DIFF signal in red (the difference between the input and output signals), and
what we refer to as an NMR (Noise-to-Mask Ratio) display in green.
This display can be scrolled and zoomed in both frequency and dB.
For a stereo signal, you can select LEFT, RIGHT or the SUM of both left and right. The
NMR signal can be turned off, if required.
Beneath the FFT window, the CODEC LIST enables the simultaneous selection of up to five
codecs. The associated MON buttons allow monitoring of a selected codec. The ARM
buttons are used when recording online to an encoded file.
To the right of the codec list are three tabbed windows; shown above is the BITSTREAM
LEVEL / TRIM window. The COMPRESSION tab provides an indication of the data
compression for the selected codecs, and the A-B tab allows A-B and A-B-X auditioning.
