I'm working on a project where I need to connect four Dayton Audio TT25-8 Puck Tactile Transducers to a Raspberry Pi. The goal is to have each transducer play a separate audio track simultaneously. Is this possible? What would be the best way to do this?
I'm thinking I would need not only an amplifier but also an audio interface, since I would need 4 separate channels that the Pi could communicate with. I'm looking for a budget friendly way to do this, so I was thinking of buying two audio interfaces, although I'm not sure if that would work. These 4 channel amplifiers and audio interfaces are super expensive so I am wondering if there's another way about this. Thanks!
