SPARS code

SPARS Code

SPARS is an acronym for the Society of Professional Audio Recording Studios.

A 3-letter code that appears on some CD recordings telling the consumer what type of tape recorder was used in the recording process. It typically comes in three types (In the code, ‘A’ means analogue, and ‘D’ means digital):

 AAD – Analogue tape recorder used during initial recording, Analogue tape recorder used during mixing/editing, Digital mastering.

 ADD – Analogue tape recorder used during initial recording, Digital tape recorder used during mixing/editing and for the mastering.

 DDD – Digital tape recorder used during initial recording, mixing/editing and for mastering.

A small number of DAD recordings were also produced.

Since CD is a digital medium, it must be produced from a digital master – therefore the last letter of the code will always be ‘D’.

As digital tape recorders only became available in the early 1980s, all recordings prior to this date that appear on CD will be AAD – having been ‘digitally remastered’. This means that the original analogue master tape has been converted (transcribed) to digital. It does not always imply that there has been any additional editing or mixing, although this may have taken place.

The SPARS code should not be taken as an indicator of the quality of the recording. There are lots of poor quality DDD recordings around, and also lots of excellent quality AAD recordings. This was particularly true in the early years of digital recording, as recording engineers were inexperienced with the new technology and did not know how to get the best from it. Even today, when digital tape recorders are inexpensive, many recordings, including many pop records, are made AAD and have excellent sound quality.

The main limitation of the code is that it only covers the type of tape recorder used, not taking into account other equipment used in the production of the recording. For example, during the mixing stage (the middle letter in the code) many DDD recordings may have actually been converted from digital to analogue, mixed on an analogue mixing console, but converted back to digital and digitally recorded, thus earning it a ‘D’ in the relevant part of the code. This is because while digital tape recorders are now relatively cheap, large digital mixing consoles are still extremely expensive. In addition to this, many recordings have effects or parts of different recordings added on to them, creating more confusion for the code.

The confusion surrounding the code and the anomalies it produces has led the inventor of the code to recommend it be scrapped in the mid 1990s. This has largely happened, and new CD releases are increasingly less likely to include a SPARS code.

Examples of recordings with SPARS codes are:

Weezer – The Blue Album (1994) – AAD U2 – The Unforgettable Fire (1984) – ADD ABBA – The Visitors (1981, released on CD 1984) – DDD
