I recorded a program for a company I am doing some consulting at. Basically the managers have to listen to it and then they are take tests to ensure they have complied with program.
The orginal plan was to burn the program to a CD in wav and let people play it on their computer but I figured most have mp3 players and it’d be easier for them to take it with them
Anyway I recorded it in .wav form from my computer using my voice. Seeing how huge the files are, I decided to compress it with LAME to mp3.
Then I was reading how if you use the mp4 format you can bookmark it. So you can stop and start. Plus it takes up less room.
So I downloaded the free aac codec from NERO and used Exact Audio Copy to compress the wav into .aac.
My first question is, I read that the files formats
[ul]
[li].aac[/li][li].mp4[/li][li].m4a[/li][/ul]
are all the same, and you can use any of them, it doesn’t matter. Is this correct?
Nero by default put in a file extension of .aac
I don’t want to confuse people so I figured I would change the extension to mp4.
Or should I just leave it.
The second question is the bookmarking thing. Is there special players that are needed or anything? If anyone has a decent website they can direct me to I’d appreciate it.
I went to Snapfiles.com and I see there are plenty of free programs to change mp4 to mp3 so if anyone has a player that won’t play the mp4 they can change it. So that doesn’t seem to be an issue.
I checked and most of the mp3 players can play mp4 so that shouldn’t be an issue.
Anything else you can suggest. These people aren’t the most computer literate.
