The most impressive thing I saw at Podcast Movement 2022 was Nomono's Sound Capsule. This replaces multiple pieces of audio equipment and processing software to capture high-quality audio with great simplicity.
The Sound Capsule comes with four wireless microphones, which record into separate tracks. The smart hardware and software processing reduces the crossover audio between the microphones.
The base station is wireless, too, and can connect to a wifi network for effortless uploading immediately after recording. The base station even has its own microphone array for capturing spatial audio or even ambient sound for noise-reduction.
While the anticipated price is high at about $3,000 (USD), it's replacing nearly that much in hardware and software. So if you frequently need a fully portable, straightforward, quick option, this could be a perfect match for you!
