One of the Nintendo Entertainment System voice channels supports playback of sound samples. Which one?

The answer is DMC (Delta Modulation Channel) because it was the only voice channel on the Nintendo Entertainment System (NES) that supported the playback of sound samples. The DMC was capable of sampling and playing back pre-recorded sounds stored in its dedicated memory, allowing for more versatile and realistic sound effects and music during gameplay. The other voice channels on the NES, namely the Pulse channels and the Triangle channel, were primarily used for generating basic waveforms and tones.
