Buying Guide
What should you look for when selecting a digital recorder for qualitative interviews?
- Storage capacity and battery life: For long interviews or fieldwork, choose models with 64GB or more and long-lasting batteries. Consider devices with USB charging or fast-charging options to minimize downtime between sessions.

- Playback options and features: A-B repeat, variable playback speed, and time-slot recording help with efficient transcription and analysis. Two-button simplicity can be advantageous for quick captures in the field.
- Security and confidentiality: Password protection or encrypted storage is important for interviews containing sensitive information. Assess how securely the device stores and restricts access to files.
- Portability and durability: A compact, metal body can withstand travel and daily use. Consider weight, size, and build quality when you’ll be moving between locations.
- Compatibility and transfer: Ensure the device supports common formats (wav, mp3) and offers straightforward USB data transfer to PCs or transcription software.
