The Linear Arithmetic 32 (LA32) is an audio chip designed around 1987 by Roland and used in several of their synthesizers. The chip uses traditional subtractive synthesis combined with PCM-based samples on the attack portion of the instrument to give a sound superior to what subtractive synthesis can achieve alone.

The term "linear arithmetic" is derived from the facts that the synthesis is all digital (linear) and a summing (arithmetic) of sounds.

The chip features 8 melody channels of LA synthesis and 1 rhythm channel.

The following synthesizers and sound cards utilized the LA32:
