Expanded from AACR2 6.5C1
Extracted from AACR2 7.5C1 Give the characteristics in the following order:
Type of recording (sound recordings and sound track films)
Playback or projection speed (all formats)
Groove characteristic (cylinders and analogue discs)
Track configuration (sound track films)
Number of sound tracks (sound recordings)
Playback mode (sound recordings)
Sound characteristics (films, videos, and electronic resources)
Colour (films, videos, and electronic resources)
Recording and reproduction characteristics (sound recordings)
5.C.1. Type of recording (sound recordings and sound track films)
5.C.1.1. Sound recordings
Expanded from AACR2 6.5C2 Give, for a disc or a tape, the type of recording (i.e., the way in which the sound is encoded on the item ).
1 disc (27 min.) : digital
4 tape reels (56 min.) : analogue
1 sound videocassettes (U-matic, 62 min.) : digital
Optionally, when available, qualify with the SPARS-Code. These three recording industry codes often appear on CDs and indicate the encoding on the three generations of 1. recording; 2. mixing/processing; and 3. reproduction .
A = analogue
D = digital
X = unknown
AAA
(analogue recording, mixing and reproduction )
AXD
(analogue recording, unknown mixing, digital reproduction )
DDD
(digital recording, mixing and reproduction )
1 sound cassette (DAT, 58 min.) : digital (ADD)
Where the codes alone would not indicate the sound quality of the final production , include a note in Area 7 with further detail, if it is known (or according to Chapter 10, if more than one copy is being described).
1 sound disc (CD, 64 min.) : digital (DDD)
(Digital recording 16 bit PCM, 44.1 kHz, editing 16 bit PCM 44.1 kHz, issued on CD 16 bit PCM, 44.1 kHz. An example of a high quality DDD. The normal expectation of DDD is that it would be high quality sound)
1 sound cassette (DCC, 29 min.) : digital (DDD)
Note: Mini disc recording, edited on SADIE, published on digital compact cassette.
(A low grade DDD. Here it is appropriate to note the detail if known, to explain the poorer sound quality, as this example is not what would normally be expected of DDD)
1 sound cassette (DAT, 58 min.) : digital (ADD)
Note: Original 78 rpm shellac disc, electrical playback processed with CEDAR DC1, DAT reproduction .
5.C.1.2. Sound track film

33 rpm (= 33 1/3 rpm )
Note that many pre-electric coarse groove discs require playback speeds less than or in excess of 78 rpm . Include the correct speed where known or make an explanatory note if the statement is in any way speculative.
1 sound disc : analogue, 81 rpm
Note: Playback speed ascertained from audition. 5.C.2.3. Sound tape and wire reels
Adapted and expanded from AACR2 6.5C3
Adapted from ARSC 6.H.2

4,75 cm/sec
9,5 cm/sec = 3 3/4 ips
19 cm/sec (= 19,05) = 7 1/2 ips
38 cm/sec (= 38,1) = 15 ips
76 cm/sec (= 76,2) = 30 ips
4 sound tape reels (56 min.) : analogue, 76 cm/sec
1 sound wire reel : 19 cm/sec
5.C.2.4. Video formats For videorecordings, do not give the playback speed. Instead, give the specification of the video format either in this area (see 5.B.2-5.B.3) or in a note, if further detail is required. By specifying the video format, the correct playing equipment and speed can be chosen.

5.C.2.5. Films and sound track film s
AACR2 6.5C3, 7.5C5 For films and sound track films give the playback or projection speed in frames per second (fps) (see also 5.C.2.6).

5.C.2.6. Formats with pre-determined playback or projection speeds
AACR2 6.5C3, 7.5C5 Do not give the playback speed if it is standard for the type of item (e.g. 4,75 cm/sec for an analogue tape cassette; 24 fps for a sound film; 16 fps for a silent film ), or for discs where the playback machine is programmed to revolve at standard speed (e.g. for CDs, mini discs). 5.C.3. Groove characteristic (cylinders and analogue discs)
5.C.3.1.
ARSC 6.C.3 Optionally, for cylinders, give one of the following groove characteristics: coarse groove (100 groove s per inch; e.g., Edison 2-minute cylinders), microgroove (200 groove s per inch; e.g., Edison 4-minute cylinders), and other.

5.C.5. Number of sound tracks (sound recordings)
Expanded from AACR2 6.5C6 If readily ascertainable, for cartridges, cassettes, or tape reels, give the number of sound tracks, unless the number of tracks is standard for the item (e.g., the standard number of tracks for a cartridge is 8, and for an analogue cassette 4). If necessary, include the direction of play (i.e. unidirectional or bidirectional). A list of examples of the numbers of tracks which may occur on sound tape formats follows.
1 track
2 track
4 track
8 track
16 track
