Sony ICD-PX470 4 GB voice recorder

This compact Sony digital voice recorder is focused on clear meeting and lecture capture, combining a stereo microphone arrangement with easy file transfer and expandable memory. It suits note-taking, interviews and on-the-go dictation, offering up to 55 hours of continuous recording according to the manufacturer and simple plug-and-play via the built-in USB.

Key Points

The recorder includes a stereo S-microphone system that captures distant or soft sounds and lets you choose between zoom focus mode and a wide stereo panorama for greater control over what is recorded. Automatic voice recording helps reduce background noise in many situations, making spoken content easier to transcribe. The unit is lightweight and pocketable, so it can be carried to classes, meetings or field interviews without much fuss. 🎧

Technical Specifications

• Name: Sony ICD-PX470
• Internal memory: 4 GB
• Expandable memory: microSD card up to 32 GB
• Maximum recording time: 55 hours (according to the manufacturer)

Benefits

Recording quality is versatile thanks to the combination of focused and panoramic modes, which allow the device to emphasise a speaker or capture the ambience of a room. The built-in USB connector removes the need for cables or docks, letting you copy files straight to a computer for editing or archiving. Battery life and the relatively large internal memory mean fewer interruptions during long sessions. 🔋

Usage Recommendations

For meetings where a single speaker dominates, use the focus (zoom) mode to prioritise that voice and reduce the prominence of surrounding sounds. When you want a sense of the room or multiple participants, switch to wide stereo panorama to preserve spatial cues. Consider adding a microSD card if you expect to record many long sessions or need to keep separate sets of files on different cards.
