KJJP-FM 105.7 is currently operating at 15% of power, limiting its signal strength and range in the Amarillo-Canyon area. This due to complicated problems with its very old transmitter. Local engineers are continuing to work on the transmitter and are consulting with the manufacturer to diagnose and fix the problems. We apologize for this disruption and service as we work as quickly as possible to restore KJPFM to full power. In the mean time you can always stream either the HPPR Mix service or HPPR Connect service using the player above or the HPPR app.

How Well Can You Hear Audio Quality?

We are marking a milestone, 50 years of NPR, with a look back at stories from the archive.


Recently, the rapper Jay Z relaunched the subscription streaming music service Tidal, which includes the option to listen to high-definition audio for $19.99 per month. Tidal's HiFi, with its uncompressed audio files, promises a better listening experience than any other streaming service on the market.

Many listeners cannot hear the difference between uncompressed audio files and MP3s, but when it comes to audio quality, the size of the file isn't (ahem) everything. There are plenty of other ingredients to consider, from the quality of your headphones to the size of the room you're sitting in to, well, your own ears.

Can you hear the difference? Take this quiz to find out. One hint: Turn your volume up.
