<div>Dear Roberta Rouge,</div>

<div>I don't know how you subscribed to this list, but the way to
unsubrcribe is not to send five messages to the list. I have
unsubscribed you now.</div>

digitally. And so a master (archival and citable) audio file is the
same as its copies, and they can be downsampled and transcribed and
the transcript will also relate to the master copy. Making edited
copies can lead to problems if you then invest effort into timecoding
transcripts to files that are not archival and citable.</blockquote>

little effort to realign my current transcripts to the archival

<b>Final Questions:<br>
</b>A further concern which emerged when I thought about downsampling
to MP3 was:<i> Would the time coding change from the original WAV
format</i>? The aim of archiving linguistic data is to make it
consistent, durable, catalogued and thus easily accessible (always
back to the original source) in the future by those to whom the
speakers allow data access.<br>
I've already had the experience of a DAT tape 'drop out' of 23 seconds
in the digitisation process. Luckily the Master copy kept at AIATSIS
had these 23 seconds of material and they could make a 'red book' copy
for our use. However, I noticed that the time coding of the first
Master CD we had was now one second out from the 'red book' copy (in
addition to the 23 seconds) and thus I wonder if any copy made from
the original Master would not share the same time coding?<br>
<br>
This is a serious issue to consider if we are to use hyperlinks to
audio recordings, and I'd appreciate any advice, comments or similar
experiences you may have.<br>
