Choppy audio playback
In general, dialup connections have trouble with streaming
audio and streaming video. People who have modem connections
usually understand the limitations on what they can actually
do in this area :)
To correct the "stuttering" effect, try increasing the "buffer audio" option to a higher value. Something like 10-20 may work better. Or, you may want to consider reducing the overall size of your files by increasing the amount of compression you are suing to generate your MP3 files.
Initial MP3 playback for modem users may be "choppy."
Once the entire file is downloaded, however, the file will
play normally. In the current version there is no option to
force the entire file to download before starting playback.
This is something that will be incorporated into future versions.
(Upgrading to newer versions of Wimpy is free.)
As for streaming videos, it all depends on how large the
videos are in file size. For example, if you put a really
large, high-quality photograph on the web, then modem users
will have to wait longer to see it because the actual file
size is large. Of course, people with faster internet connections
will be able to download the file faster. The same thing applies
with video, the larger the file, the longer it will take for
modem users to download the file. The best thing to do is
to test different compression sizes vs. quality.
There are two things you can do to minimize
1) Use the Customizer Tool and increase the "Buffer Audio" to a higher value. Something like 10 or 30 seconds will help. For dial-up connections, you may even want to try a higher number such as 45 or 60.
2) Install Wimpy into two separate folders on your web site. One for "Broadband" users, which contains higher quality (and therefore larger files)
and the other for "Dial-up" users, which contains lower quality, and therefore smaller files). Then present the user with
a choice prior to launching Wimpy.
The following chart can be userd as a guide when creating MP3 files so that you can encode / compress your MP3 files for a "target" internet connection speed.
|Type of connection:
|Dial up modem
Audio artifacts will be present. Good for talk radio.
56k modems shouldn't have too much trouble with these
files. 28.8k modems will probably choke.
|DSL / ISDN
Wider range of tone, little to no audio artifacts.
56k modems may experience some choppiness, but not
Decent sound, not quite as good as a CD, but close
56k modems choke. DSL / ISDN may experience some skipping
from time to time, but not much.
