Frequently asked questions

Most models support both. Use Continuous Recording for full coverage, or enable Voice-Activated Recording (VOR) to save storage and battery by recording only when sound is detected.

Connect the device to a computer via USB (or remove the memory card if applicable). Recordings are stored as standard audio files, so you can copy, rename, and organize them easily.

Many models support recording while charging for longer sessions. For best stability, use a reliable 5V USB power source and avoid fast-charging adapters unless the product specifically supports them.

For best clarity, keep the recorder within 1–3 meters of the sound source and avoid covering the microphone. Background noise (wind, traffic, fans) can reduce clarity—quiet placement works best.

Laws vary by country/state. Always use this device for lawful purposes, and obtain consent where required—especially in private spaces or when recording conversations.
