PCM 16 or 24 32 to 192 4 .WAV yes
FLAC 16 or 24 32 to 48 4 .FLAC no
FLAC 16 or 24 32 – 96 2 .FLAC no
MP2 (mono) 16 32, 44.1,, 48

MP2 (stereo) 16 32, 44.1, 48
(64, 96, 128, 160, 192, 256, 320, 384) * 2 .MP2 no
MP3 (mono) 16 32, 44.1 48
(32, 64, 96, 128, 160, 192, 256, 320) 1 .MP3 no
MP3 (stereo) 16 32, 44.1, 48
(32, 64, 96, 128, 160, 192, 256, 320) ** 2 .MP3 no
* For MP2-Stereo, the per-channel bit rate is half of the selected bit rate.
** MP3-Stereo uses Joint Stereo Coding, which improves per-channel resolution over MP2-Stereo but
can not be quantified into a specific per-channel bit rate.
iXML
The 744T includes iXML (revision 1.5) data in addition to the broadcast wave extension data. For
iXML-aware software applications this data is available. For applications that don’t recognize iXML,
this information is ignored.
Notes
iXML supports notes fields. From the File Viewer select OPTIONS, then Notes.
Using an external keyboard via the CL-1 Remote Control and Keyboard Interface the entry of notes
is much quicker than using the Rotary Switch.
If time code is turned off, metadata will still be written. Post-record metadata editing can be performed
using a Mac OS or Windows based computer with Sound Devices Wave Agent Beta.
See Wave Agent
Beta for more details.
Recording Time Calculation
The calculation of available 744T recording time involves three factors:
• track count - how many concurrent audio tracks are selected for recording.
