I'm researching digital voice recording to record long workshops... 6 to 8 hours. Questions: 1. Can the T3 be used for this? A. Would the auto-off kick in and turn it off? B. If the auto off doesn't turn it off..how long would the battery last? C. If battery life is the limiting factor...can I get that power sled thing to keep it going? D. Can I save the files to disk? 2. If T3 is not the optimum device for this purpose...and digital voice recorders are.... A. Where can I get info on which voice recorder to buy..and what to look for in such a gadget? B. I looked at a digital voice recorder at a store 2 weeks ago, and noted that it said on the back panel that the device had x number of "folders". Would this limit the amount of recording you could do at any one time...or can you just set the thing and let it run for hours?
