Audio formats(Edit)

Classic Frye (1/6/2014): I always record in WAV at the highest quality I can for the space I have to work with, then flip to whatever format the media will be distributed in and archive the WAV file. At 16 bit it's roughly 11m per minute and 24bit (shucks! I forgot, but it eats drive space like I eat cookies).(Edit)

So, for streaming from your web site flip to 128k mp3, for download 192 - 320k mp3. The higher quality is better for broadcasting, so I'd try to get the jock to play the WAV, but 320k mp3 would be OK, 192 passable, depending on the station. (If you are going to put it on KLCK it might be a good idea to call them up and ask them how they like to get it, and do that for other stations as well). Audacity will nicely handle the conversions for you.

If you know about raster graphics like BMP and TIFF and how sharp they are, but big files, and you flip them to JPG they are not as sharp, but the file size is a lot smaller. You can take that JPG and flip it back to BMP or TIFF, but they will never be as crisp as the originals because of data loss in compression where there was a lot of averaging of colors going on.

WAV is the really high definition audio format and mp3 and other formats are sort of like the JPG that had all the averaging going on. The only compression algorithm that successfully restores to high def WAV is FLAC, which is why it is the choice of tapers everywhere, even though it doesn't "squish" as far in file size , so there's another conversion if you want to archive the master, but need drive space.

For archiving you can also burn them to CD then rip them back if it got burned in regular CD format instead of data format.

Hope that's helpful.
