AMR has various meanings in the General category. Discover the full forms, definitions, and usage contexts of AMR in General.
AMR is a specification developed by Intel for packaging the analog I/O audio functions of modem circuitry together with a codec chip on a small board that plugs directly into a computer's motherboard . The small board is called a riser because it rises above the motherboard rather than laying flatly on it. Having this circuitry on a riser means that it doesn't have to be part of the motherboard itself.
