Flash Video Can Have Near CD-Quality Audio
I confess. I’m a YouTube music junkie. I’ve found vintage and rare recordings at YouTube that I couldn’t order from iTunes, even if I had the budget to do that. But have you listened to YouTube audio on a decent sound system? Or even with a decent set of headphones? First of all, it’s mono—and not great mono quality at that.
When you create your own Flash Video, using Flash Video Encoder, you can generate downloadable videos with CD-quality audio, and yes, I’m talking about stereo audio.
At the maximum encoding quality available in Flash Video Encoder, you can generate videos with 256 kbps (kilobytes per second). That is generally considered to be “near CD quality.” I find that 192 kbps is close enough to CD quality stereo, and, obviously, the less audio data in the video file, the faster the video downloads.

At the other end of the spectrum, when you create your own Flash Video, you can generate audio quality even lower than that used at YouTube. That makes for a faster downloading video, and is acceptable for narrated instructional videos, or stripped-down files that will download quickly over a slow Internet connection.
