Hi,

Just would like to share an article on audio encoding optimization for
podcasting. No need to think what bit rate to choose the batch file
will automatically encode your podcast with the best bit rate to
preserve the best quality and smallest file size. The approach was
tested on MP3, Nero AAC and OGG.

This paper will give you understanding on how one can achieve better
compression ratio by bit rate optimization. The key point is that our
approach describes a fully automated manner of choosing the bit rate
that will preserve the audio quality you define. Read this paper
through and find out how to save on size when encoding your podcasts,
save on bandwidth when transmitting your audio streams in the network,
make more audio tracks fit your memory stick when grabbed from a CD,
or store more audio books on your mobile device. This paper will tell
you how to save up to 50% on audio file size and up to 50% on the bit
rate you encode your audio with still having a descent sound quality.

quality in this blog post:
