Notes about the OMA file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The OMA file type is primarily associated with 'Sony' by Sony Corporation of America. These files are in Sony's ATRAC3 format. There appears to be several ways to read/convert these files. One is to use a program like SonicStage to burn them to a CD. Then, use whatever program you like to rip the audio off the CD and convert to whatever format suits. You should also be able to use the original Sony software with the Tools | Options | CD Recording | Select Format menu to convert to a .WAV CD format which can then be ripped. Can be played with SonicStage 2.1+.
