From RISC OS
AMPlayer is a module for playing Audio MPEG files. Its primary use is playing MPEG 1.0 Layer III player (MP3), although it also supports MPEG 2.0 and 2.5.
AMPlayer supports ID3 and ID3v2 tags.
As a module, AMPlayer can be accessed from a taskwindow, although it is more commonly used with a front end. The binary download includes a simple front end, and command line decoder tools.
The latest release is version 1.42. This runs on RISC OS 3.50 or later, and also 32 bit versions of RISC OS as used on the IYONIX pc and A9home, up to and including the latest ARMv7 and ARMv8 processors which don't allow unaligned memory accesses.
