.Wav, 60 minutes.
Regarding the downloaded MP3 "debate" file from 4wd's post: It was quite interesting to notice how much faster it is to convert from MP3 to WMA, than the other way around.
I used Aimersoft Video Converter Ultimate to convert the 3 hours 'debate' file from MP3 to WMA. It only took 2 minutes, but it took 5 minutes to convert it back into MP3! My converters will not work any faster than 30, 40 or 50 times the normed play time - depending on the settings. This is where the key to conversion speed is to be found, meaning that most programs probably will convert with the exact same speed!
As Hank said, in this discipline (1 long file, from wma to mp3) MediaCoder was in fact slower than the other converters. I used to have a lot of converters, and still have some license keys, so I was tempted to do a thorough test. But the European Championship tournament in female Handball is beginning in a few minutes, so I skipped the lot and went strait to the target: If conversion speed really is so important to Hank, he should consider not converting at all; it is a waste of time, just in order to halve the size of the files! Speaking of "halves"; if you must
change any settings, divide any number with 2 or 4, avoid odd dividers. Don't use "Preset > Voice", it takes forever to create.
Sorry; I am out of time (hopefully not too literally!!!) Handball girls, here I come!
