3 For each enabled audio channel (based on the Audio Coding Mode), specify the input
file. Click the Browse button and select the audio file you will use for the channel, then
click Open. All audio files must be the same audio file type.
4 If any of the input files are not AIFF or WAV, you may have to specify whether they are
little- or big-endian. This is only the case for PCM streams without file headers. If you
specify such an input file, you will need to select from the following options:
• PCM files are big-endian (Mac)
• PCM files are little-endian (IBM)
5 To audition an audio channel, do the following:
• Select the input field for the audio channel you want to hear and click Play.
• To adjust the volume, drag the vertical slider.
• Click Stop to stop playback.
• To begin playback from a specific location, enter a Start Time in the Audio Playback
section.
