My first ever use of the wamug group and I stuff up. This was an old
message (yesterday) I had drafted and since then I found out more
from the wamug website.
However, there is still a problem:
The podcast in Garageband (v4.1.2) was sent to my iTunes (8.0.1).
The original version was 3.4 MB. When I get iTunes to convert to a
mp3 files, the size increases to 8.1MB. As I want to upload this to
Hipcast as a podcast (and later to iTunes), my gut feel is that the
size is too big.
The bit rate has changed from 64 kbps to 192 kbps in the conversion.
Is that the reason for the increase in size?
Yes, a higher bitrate creates a larger size file.
If you want to change the bitrate in iTunes:
1. Choose iTunes > Preferences - General and click Import Settings.
2. Choose an encoder from the Import Using pop-up menu (you select MP3)
3. Choose a bit rate from the Setting pop-up menu (you select custom)
Then under the Stereo Bitrate select a lower Bitrate
4. Click OK.
5. Select your track in iTunes then choose Advanced > "Create MP3
Version"
Unfortunately, there is no such thing as a typical bit rate for a
podcast, as they vary greatly from as low as 32 kbps up to around 128
kbps.
As a rough guide to the use of different bit rates however, the
following may be helpful:
320 kbps - Virtually indistinguishable from original CDs
128 kbps - Typical for musical MP3s and quality podcasts
64 kbps - Common bit rate for speech podcasts
48 kbps - Reasonably common for longer speech podcasts
32 kbps - Poor, usually used to reduce download times
Listen For Yourself:

<http://www.siliconbay.co.uk/services/32kbps.mp3>
Is there a smarter way to do this?
I think you can direct Export to MP3 format in GarageBand v4.1.2
The Podcasters on WAMUG can probably give you more advice on Podcasting.

Thanks again

I have created a podcast in Garageband (v4.1.2) and sent it to my
iTunes (under the Share button in Garageband). I then dragged it to
the desktop just to make it easy to upload to Hipcast. It uploads
fine, but ends up in the video section, not the audio which is
where I want it. The podcast file has a suffix .m4a. If I convert
to an mp3 it has a suffix .aif. Will this version upload better?
I have done a search of the internet but with no joy. Old advice
says "convert to AAC" under the advanced button in iTunes, but
there doesn't appear to be one with iTunes 8 (8.0.1).
I am grateful for any advice or websites that will help. Please
keep any response simple as I have no idea what .m4a, .aif or AAC
mean. Simply put, what is the best way to present a podcast to the
world, well, Hipcast anyway?
