When designing a microphone assembly the other day, I reached for an electret condenser microphone capsule without thinking. To be strictly accurate I ordered a pack of them, these small cylindrical ...

Electret microphones are capable of high-quality output, and are prized for their smooth frequency response. However, unlike other types, they can’t simply be plugged directly into a mixing desk.

Because of advancements in microphone technologies and small-signal A/D (analog/digital) integrated circuits, Electret Condenser Microphones (ECM) are now able to deliver digital audio output, which ...
