What does AAERT recommend against when using microphones?

AAERT recommends against using batteries when operating microphones primarily because battery-powered microphones can introduce a variety of risks and operational challenges. Batteries can malfunction or run low during usage, potentially leading to audio interruptions or failures in capturing important audio data. Additionally, relying on batteries adds an element of unpredictability, making the recording process less reliable, which is crucial in environments where accuracy and dependability are paramount, such as legal and official proceedings.

In contrast, other choices such as using external speakers, condensers, and interfaces have valid applications and can enhance the audio recording experience when used appropriately in professional settings. For example, external speakers can help in monitoring audio quality, condenser microphones are widely used for their sensitivity and clarity, and interfaces can improve sound quality by connecting microphones to computers effectively.
