Available with 32GB or 64GB internal memory, this recorder stores a substantial number of WAV files at 192 kbps. With 32GB, it saves approximately 188 hours of audio; the 64GB version stores around 376 hours.

Everyday Home Use

For personal recording tasks such as voice memos or interviews, the one-key record and playback system is straightforward. The recorder also functions as an MP3 player, playing WMA, WAV, MP3, and OGG files through headphones via the USB audio jack.
