Voice recorders allow users to capture moments and never lose a thought. While analogue types rely on cassettes to store audio, newer models feature flash drives. Models with higher storage capacities and memory card slots can store longer recording or shorter ones at higher fidelity.
Recorders often use the MP3 format, but some record lossless formats and may be a better choice when recording music. Finally, models with jacks for external microphones allow higher recording quality.
