Voyager (007)
See also Fixed field codes for sound recordings (008)
Multiple 007 fields are appropriate whenever more than one code would apply to the recording in any of the various subfields. Stereo/mono (SND) and capture/storage (C/ST) would be the most frequent candidates.

Update: You may begin using code "q" for recordings with more than two playback channels as per changes regarding sound recordings: 007/04
Configuration of Playback Channels code "q" definition. In order to allow for a direct equivalent coding for surround sound, code "q" was redefined to allow for playback configuration for recordings with more than two playback channels. Previous to this change, code "q" was restricted to quadraphonic recordings (four playback channels), a limitation that resulted in the use of code "z" for non-quadraphonic recordings with more than two playback channels. In order to align with equivalent definitions of code "q" in Motion Pictures and Videorecordings (007/08 - Configuration of playback channels), the definition of code "q" in Sound Recordings 007/04 was revised to read:
Configured to be played back on more than two channels. Use this code for Dolby surround sound tracks and other multichannel techniques.
The definition has already been revised in the MARC Documentation (www.loc.gov/marc/bibliographic/bd007s.html); however, the renaming of the data element to Quadraphonic, multichannel, or surround has been delayed because it needs to be documented in the Content Designator History section. The change will be made official and documented in the next MARC Update.
note 1: From Kathy Glennan, 8/5/15, MOUG-L
note 2: Quadraphonic, multichannel, or surround: The sound recording is configured to be played back on more than two channels. Use this code for Dolby surround sound tracks and other multichannel techniques. (See Technical Bulletin 264 (Formerly, Quadraphonic.)
note 3: LC practice is to "assume a CD is stereo unless there is a clear indication (wording on container, printed insert, or the disc itself) that the recording in hand intended to be mono." (MLA-L correspondence on 3/11/2005 from Joe Bartl, Music & Sound Recording Team 1, Special Materials Cataloging Division, Library of Congress)
note 4: Enter the code in subfield ‡f, even if the information does not appear on the item.

note 5: The third letter "D" (for "digital") in the three-letter SPARS code usually corresponds to code "e" in Playback characteristics (OCLC ‡m)
When a recording does not clearly indicate playback configuration, users may either use code u in subfield ‡e or infer a configuration from the recording itself.
note 6: The first letter "A" (for "analog") in the three-letter SPARS code usually corresponds to code "e" in Capture & storage techniques (OCLC ‡n)
SPARS codes appeared on compact discs through the mid 1990s to indicate the type of equipment used to produce the disc. Its emphasis only on tape recorder as equipment is one reason it was discontinued. However, when the code appears on a compact disc, it can be useful to determine Playback characteristics and Capture & storage techniques.
1st letter = type of audio equipment (usually a tape recorder) used during initial recording (analog or digital)
2nd letter = type of audio equipment used during mixing/editing (analog or digital)
3rd letter = type of mastering used (digital only)
AAD = analog equipment for initial recording; analog equipment for mixing/editing; digital equipment for mastering
ADD = analog equipment for initial recording; digital equipment for mixing/editing; digital equipment for mastering
DDD = digital equipment for initial recording; digital equipment for mixing/editing; digital equipment for mastering
DAD = digital equipment for initial recording; analog equipment for mixing/editing; digital equipment for mastering
