RE: [AV Media Matters] Digital audio file formats


Just to get a better understanding of your content, this is all audio
content or is it a mix of audio and video?

For audio, you might want to look at Digidesign ProTools.  This would
allow for you to capture the content in an uncompressed format (WAV
file).  This will produce about a 445Kbps stream to storage or 200MB of
storage per hour of content.

How do you plan to catalog the content?  Are you looking at making this
a living system archive (making the archive searchable)?

Subject: [AV Media Matters] Digital audio file formats

We're designing a preservation plan for the Alaska state government,
for their collections of legislative recordings. We are planning on
advising that instead of making preservation copies to a tape format
or CD, digitization and storage on hard drives be done (stored
off-site from the original tapes), achieving access copies and
backup migration in one step. Any thoughts or concerns anyone has
with this, I'd be pleased if you'd pass them along.

I'd also like to hear suggestions regarding file formats to capture
in- ".wav" files have been suggested. Anyone willing to comment (on
or off the record) on this vital decision area, please contact me.
It is highly likely the data will end up on one of the state's
servers, so there will also be other copies of the data out "in the
world" once we digitize.
