Generating AUDIO ECHO using Atmega32 microcontroller. But now I can do this very easily by a simple digital signal processing using a microcontroller. It’s concept is very simple, ie we need to apply a proper delayed feedback in digital samples with in a circular buffer. I did this using an atmega32 microcontroller and it worked fine.

I'm thinking that the microcontroller will read the data from the eeprom and then send the information to a dac for audio playback. However, I'm not sure if I need to convert the mp3 file into another ...

The combination of the C with the R sets the lowest frequency that can pass through to the ADC. DC (the ultimate low frequency) is blocked, while AC passes through. In this case, the cutoff frequency would be 1 Hz, which is plenty low for audio. The DC bias is provided by something in the middle of the ADC range, with low noise.
