1. Regarding the availability of analogue tape, please see this url: http://www.prosoundnews.com/articles/article_1573.shtml It seems that analogue tape will continue to be available, so the most prudent practice, making both analogue and digital transfers, will continue to be possible. 2. Work flow for archiving analogue to digital: a. Procure excellent playback equipment for each analogue format. In playback, for best quality, you may need to adjust the azimuth of the playback head for each batch of recordings. This is the sort of thing a competent audio engineer understands. b. Determine which method of analogue-to-digital-conversion is appropriate for your needs. For very best quality an external A/D converter may be appropriate. However, a high-quality sound card such as the Lynx 2 may suit your needs. (An added advantage: If you do the conversion with an external A/D converter, you'll still need a sound card to squirt the audio into the computer. So using a sound card like the Lynx combines the two processes.) Consider which sampling rate and bit depth are appropriate for your conversions. If you're only going to make audio CDs, you may decide that 44.1kHz/16 bits is the right choice, since this is what is used for commercial CDs. For high-end audio conversion, typically higher sampling rates are often employed, either 88.2kHz/176.4kHz (multiples of 44.1) or 96kHz/192kHz (multiples of 48kHz) with a bit-depth of 24 bits rather than 16. c. With the digitised audio in the computer, an editing programme is needed to manipulate the audio before archiving it to CDR or whatever. I use Samplitude Producer V8 for this purpose. d. Typically, I make transfers at a high sampling rate, and archive these original transfers to CDR as data files in WAV format. Then the audio is resampled to meet the needs of audio CDs, which are then created from within Samplitude using its ability to make Redbook CDs (which is what CD players need). While there are no hard data on CD durability, many posters on this list like the Mitsui Gold CDs. The Archival grade costs around $1.20 in quantity. e. Logging the digitised audio. This needs to be thought through. It's considered reckless behaviour to write on the part of the CD's surface that has audio. Writing only on the innermost portion, closest to the centre hole, with a pen approved for CD usage is considered good practice. With the burnt CD safely lodged in a hard case, you'll need to create a liner printed with all the important data. It's fairly easy to find a pre-formatted Word file containing a blank liner. Then with Word and a laser printer, liners can be created. An important aspect of logging: Maintaining a catalogue as the work proceeds. NB: Some batches of tape manufactured in the 1970s and 1980s had a defect now called "sticky shed syndrome" which only surfaced later. If you're working with reel-to-reel tapes you'll need to look for this during playback. If tapes have this problem, it can be cured temporarily. But that's yet another discussion. Archiving can be time-consuming. You may wish to ascertain whether there's funding to employ a grad student to do it.
