Presto Sound Library Open Beta

Background service to add support for variable speed or pitch for playback of MP3 and Ogg Vorbis files. AAC is not supported due to existing patents.

I have been informed that the following apps have added support for Presto:
- BeyondPod Beta (not on Android Market)
- DoggCatcher
- PodTrapper
- Pocket Casts

The Presto developer is a different developer from those applications. Those developers are not responsible for Presto's implementation, bugs, or cost.

Presto is still in beta. Bugs are listed at the end of this description. Please e-mail me if you find new bugs. I apologize for the lack of updates; I bit off way more than I can chew this semester. Work is ongoing, but I can only spare a few hours at a time on some Mondays. Please be patient.

Apps using Presto must be restarted after upgrading Presto.

Download problems are a problem with the Android Market, not with Presto. See these pages for potential solutions:

For developers: See the home page for nearly drop-in code that replaces android.media.MediaPlayer, using Presto when available, or gracefully degrading to use the default Android MediaPlayer when not.

Known bugs (please e-mail me if you find any new ones or any of these impact you too severely; I have no means to respond to Market comments). Asterisks (*) indicate bugs that have not been observed in a while; please e-mail me if you encounter them so I can confirm they are not fixed.

Remember that sending an e-mail is a lot more likely to get a problem fixed than anything else (such as posting a comment).
