Working Principles

The ISD4004-12MP utilizes flash memory technology to store and retrieve audio data. When recording, analog audio signals are converted into digital format using an internal ADC (Analog-to-Digital Converter) and stored in the flash memory. During playback, the stored digital audio data is retrieved from the flash memory and converted back into analog signals using a DAC (Digital-to-Analog Converter), which can then be amplified and played through speakers or headphones.
