Firmware is software embedded within hardware. In this case, the hardware is an acoustic recorder.
Firmware updates often enhance hardware functionality by improving compatibility with other devices, fixing bugs, or adding new features.
Updating firmware helps users avoid encountering bugs we've already identified and fixed or adds new features.
In some instances, customers require consistency to follow a specific protocol. For example, they might need to maintain the exact settings from the previous season to compare results.
