128 GB Voice Recorder for Lectures and Meetings

The arungo ZD70 captures audio in WAV or MP3 at 1536 kbps using an omnidirectional stereo microphone. It ships with a pre-installed 128 GB TF card and a 1.44 inch display. The lithium-ion battery delivers 50 hours of continuous recording on a single charge. Students, professionals and journalists can record, save and playback files instantly.

Upgrade from Low-Capacity or Voice-Only Recorders

Older dictaphones with limited internal memory force frequent file transfers or risk missing content. This unit replaces them with 128 GB of storage and voice-activated recording that starts automatically when sound is detected. The jump is worth it when you need day-long capture without manual intervention or when password protection is required for sensitive interviews.

Capacity and Headroom for Extended Sessions

The 128 GB card holds thousands of hours of MP3 recordings or hundreds of hours at the highest WAV quality. Voice activation extends practical runtime by pausing during silence, making 50-hour battery life sufficient for multi-day events. It runs out when storage is full or the battery depletes; both are resolved by USB-C file transfer and recharging.
