Purpose and audience

The GL-88 is a compact digital voice recorder with 32 GB of built-in memory for students, professionals and anyone who needs reliable audio capture. It records in WAV format and offers up to 100 hours of continuous recording time. The titanium CNC body measures 95 by 25 by 13 mm and weighs about 53 g, making it easy to carry in a pocket or on a belt clip.

Build integration and connectivity

A single USB connector handles both data transfer and charging from a 5 V 1 A supply, so no proprietary cables are required. The built-in 18 mm dynamic speaker lets you review recordings without headphones, while the 0.96 inch TFT colour screen shows status and menus. Dual microphones and a line-in option give flexibility for lectures, meetings or telephone recording, and a boot password protects stored files.

Sustained-load behaviour

The lithium battery provides up to 40 hours of operation per charge, supporting long sessions without interruption. DeNoise 4.0 with CVC algorithm adjusts noise-reduction levels in real time to keep vocals clear in changing environments. Voice-activated recording splits files automatically to save space, and power-off auto-preservation safeguards the current recording if the battery runs out.
