OTR Audio PDA Player Project


This is a project to develop software for an OTR MP3 / OGG player. It is designed to run on the Sharp series of PDAs. Such as the SL-5000 and SL-5500. This software is GPL.

OTR is Old Time Radio. It is radio shows from the 1930-1950, which is called the golden age of radio. This was the era before television when radio was the main entertainment medium in the home. It is popular to collect these shows in MP3 format. They have unique features associated with them that is different from music. This makes many MP3 player useless with these programs. These programs are typically encoded with bit rates of 24, 32, or 48 kbits. They are mono and most have a sample rate of 22050 Hz. This project is to make a MP3 / OGG player that is optimized for these type of files and not music MP3s.

V3.0 adds support for the OGG format. It also fixes a bug where if one pressed play right after power on it would skip several files since the CF was not yet mounted. This is now fixed.





To run this software you will need to download the software specified under the software section of the Resources section.
