7.2.6 Input Files

The Input Files that are required for the encoding process must be loaded into this section of the user

interface (see Figure 7-5 and Figure 7-6). Input files may be loaded either by drag-and-drop into the

appropriate text field or by double-clicking on the text field and selecting the source files from the file

browser window. All active channels should be populated with mono or stereo audio input source files.

The selected channel layout determines which audio input fields must be populated. Supported audio

input file types include LPCM wave, Broadcast LPCM wave (.wav) files, and LPCM Audio Interchange

File Format (.aif).

The labels running vertically on the left side of the Input Files window pane from top to bottom

correspond to the active channels of the selected channel layout. If a channel is not active, then that row

will not be selectable. The labels will change dynamically to reflect the channel layout that is selected.

The column to the right of the Files text boxes labeled ‘Ch’ specifies which channel of the input material

will be used in the encoding processing. If a stereo input file has been entered, Left (‘L’) or Right (‘R’)

will appear in the column. An ‘M’ will be displayed if the input source material is a mono file.

The column labeled ‘Bw’ specifies the bit-width of the source file. Typically this value is 16 or 24 bits.

The column labeled ‘Fs’ specifies the sample rate (F = frequency, s = sample) of the input material. The

column labeled ‘Duration’ denotes the length of the input file in HH:MM:SS.MSEC where HH denotes

hours, MM denotes minutes, SS denotes seconds and MSEC denotes milliseconds.

If a desired input file is incorrect, positioning the mouse over the file and clicking the right mouse button,

will display a pop-up menu showing a “CLEAR” button. Selecting this button will clear out all of the

values in columns (i.e. Bw, Fs, and Duration) associated with the selected file. If you need to clear all of

the input files, the “Clear All” button will clear all of the input files in one step.

Note: Input files may have varying durations. The encode process will encode up to the

longest file duration. For example, in Figure 7-6, the input files have duration of

00:00:10.000 and 00:00:30.030. The process will create an encoded file up to 00:00:30.030

in length. The shorter files will be padded out with 0’s (-INFdB).

Note: The input source material may be 16-bit or 24-bit resolution mono or stereo in ‘.wav’

‘.aif’ or ‘.aiff’ format only.
