Hmmmmm, I don’t believe the issue is QUITE that black and white!
Seems most think better quality = BETTER.BUT – the hitherto unmentioned DOWNside is SIZE.
I must say I was not aware of any difference in quality whatsoever beetween 1-3 and 4-5, but I DID most definitely notice the ever escalating file SIZE dropped back dramatically for 4 and 5!
In fact if it hadn’t, I’d probably not have been bothering listening to many more (and yes, I’m – most of the time – on DIALUP speed, along with probably 30% of internet users).For the record, durations and file sizes so far (with the original 16.000 versions of 4 & 5):
#1 – 18min – 16MB
#2 – 22min – 21MB
#3 – 24min – 22MB
#4 – 29min – 10MB !!
#5 – 37min! – 13MBMay 31, 2006 at 6:59 am #145449Eagle_KiwiMemberJeff wrote:Crap… Audacity doesn’t allow me to encode MP3s at 44… it’s 24, 48, 96, 128… no multiples of 11. … …
?? My Audacity (1.3.0-Beta) offers the following Project Rates:
8000
11025
16000
22050
44100
48000

96000Yes, that’s true for project rates, but if you check the MP3 export rates (Edit > Preferences > File Format Setup) you’ll see that the MP3 Export setup only allows 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, etc.
May 31, 2006 at 1:46 pm #145450Eagle_KiwiMemberSorry Jeff. Fair enough. (I’m out of my comfort zone here 😉 )
I’ve searched a bit for a solution, but to no avail. Though I’m surprised to find THIS useful looking outline of podcasting with Audacity, which makes no mention of any “11/22/44” problem.
May 31, 2006 at 1:58 pm #145445SpikeMemberI think we’re confusing two different parts of the MP3 codec here, let me clarify.
Bitrate is the quality. Standard bitrates are usually 96,128,192,256,320, etc. The higher the number, the better the quality. You can even find out the bitarte by taking the filesize in Kilobits and dividing by the number of seconds (hence “kbps” = kilobits per second).
On the other hand, you have the MP3’s bandwith, or sample rate as iTunes calls it. This is a number measured in kHz, and also determines the sound quality, but to a lesser extent. Most songs are encoded in either 44.100 kHz or 48.000 kHz (right-click, Get Info on a song in iTunes, and you can see the Sample rate there along with the bitrate) Most people don’t worry too much about it, but in our case, it’s important.
If you don’t believe me, open a song in Audacity that has a bitarte of 128kbps or 192kbps, and re-encode it at about 48 or 56kbps, then play it. It will sound much, much worse.
So Jeff, please don’t encode our podcasts at 48kbps, it will sound like utter crap. My suggestion: Encode at 128kbps and 44.100 kHz sample rate. With any luck, the flash player will have us all sounding normal again 😉
