Audio Samples

The world is going digital. However, digital audio does not guarantee good subjective audio quality. Digital audio systems have wider dynamic range (soft-to-loud) than analog systems, but they can also have annoying artifacts at low bit rates, due to the compression algorithms, that can cause rapid listener fatigue. Some listeners describe the effect as "swishy" or "underwater". DRE presents these real-life audio samples for you to make your own informed decision. We believe they are compelling evidence of the enormous potential of our digital subcarrier system. But don't take our word for it, listen for yourself!

Clip One The first audio sample demonstrates the quality of current FM analog SCA broadcasts, such as Reading Services, in good reception conditions - excerpt courtesy of Minnesota Public Radio and Minnesota State Services for the Blind.1.3 MB
Clip Two The next sample demonstrates the audio quality of FMeXtra combined with aacPlus at 32 kbit/sec for a male speech segment:1.5 MB
Clip Three and Four FMeXtra with aacPlus can also achieve excellent music quality at low bit rates as the following stereo clips at 32kbit/sec and 40kbit/sec, respectively, clearly demonstate:

The audio samples are stored in non-streaming .WAV file format and are very large, several megabytes each.
A broadband connection is highly recommended. If the audio playback is choppy, try increasing the buffer size in your media player to 20 seconds or more, or download the entire file before playing.
