Zoom H4n Handy Portable Digital Recorder
This may be more digital recorder than you need for simple vocal content, given there’s so many more features here than any of the devices on our list. The H4n comes with a pair of X/Y stereo condenser mics designed to be equidistant from your source of sound. This provides a more uniform recording and prevents time delay, so you have true stereo sound.
You can record four channels of sound, combining the integrated X/Y microphones with externals of your choice and an onboard mixer lets you tweak the EQ so you have a fully balanced recording. The H4n's microphones can record up to 24-bit/96kHz resolution in linear PCM WAV files or smaller size MP3 files if you prefer.
The H4n includes multiple features like speed control playback, background noise suppression, file editing, automatic recording that triggers when the device detects sounds above a certain decibel level, and DSP effects including compressor, chorus, phaser, delay, and reverb enhancements.
Rounding this device out is an expandable card slot for SDHC cards, which means you have near unlimited storage capacity. Battery life lasts a considerable amount of time and can work up to 10 hours if it’s in stamina mode.
