72GB Magnetic Voice Recorder

The Tallkcoder recorder provides 72GB of internal storage rated for up to 7000 hours of WAV format recording. It is designed for students, professionals and anyone who needs a portable device for lectures, meetings, interviews or classes. A 3.5mm headphone jack allows direct playback without a computer.

Sustained Recording with AI Noise Reduction

The device uses a DSP 5.0 chip with triple intelligent digital noise reduction to continuously filter ambient sound during long sessions. Voice activation pauses recording during silence, conserving storage and battery life across extended use. Magnetic mounting keeps the unit fixed on metal surfaces so handling noise is minimised throughout the session.

USB-C Transfer and Practical Limits

Files move to a PC over the USB-C interface using the supplied data cable and C-port adapter. The 72GB capacity sets a hard ceiling on total recording time, and the WAV format produces larger files than compressed alternatives. No wireless or cloud sync is included, so all offloading requires a physical connection.

Questions about this item

How much heat or fan noise does the 72GB recorder produce when left recording all day?

The device has no fan and uses a solid-state design, so it runs silently and generates negligible heat even during continuous 7000-hour sessions.

What must I already own to transfer the WAV files from the USB-C port?

You need a computer or phone with a USB-C socket; the box includes a USB-C data cable and a C-port adapter for older USB-A ports.

Can I plug my existing 3.5 mm headphones straight into the recorder for playback?

Yes, the built-in 3.5 mm headphone jack accepts standard wired headphones without any extra adapter.
