Q: What are the benefits and costs of upgrading to Pandora One?
High Quality 192Kbps audio streams, the highest-quality streaming music-discovery available in the US, for every song in our collection. High Quality 192Kbps streams are currently available for:
- Pandora on the Web (on your computer via
www.Pandora.com and the Mini Tuner),
- Pandora One Desktop Application
NOTE: Pandora Mobile and Pandora In-Home Devices do not currently support 192Kbps streams, although we're very interested in expanding High Quality audio options at some point in the future.
