A "Sampler" is a device or software used to capture and play back audio samples. It allows musicians and producers to manipulate sounds, creating unique compositions by layering different audio clips. Samplers can be found in various forms, including hardware units and digital audio workstations (DAWs) like Ableton Live or FL Studio. In addition to music production, samplers are often used in live performances, enabling artists to trigger sounds on-the-fly. They can work with a wide range of audio formats, making them versatile tools for both studio recording and stage setups. Popular samplers include the Akai MPC series and Native Instruments' Kontakt.
