The best digital voice recorders are ideal for capturing audio of all kinds in the highest quality. Sure, you can use an app on your smartphone but they're always going to be limited by the quality of the microphones. And that's not to mention interruptions from the phone and battery life issues.
From recording a lecture at college to capturing a loud gig, the ability to adapt makes the best voice recorders well worth having. Many have longer range microphones and the ability to adapt pick-up based on the room noise. Lots are built specifically to capture a voice in a certain direction – yup, very secret agent like.
Other features worth looking out for include multi-track recording, adjustable stereo microphone arrays, and multi-input capture. The ability to replace batteries and swap out memory cards are also useful to keep your recording longer without the worry of charging or running out of space.
Prices start at around $25 but go all the way up to around the $400 mark. So it's worth thinking about what you actually need before picking the best digital voice recorder for you. It could save you money and end up getting you a far easier to use setup that does what you need just fine.
For top-end uses there are super recorders like the Zoom H6, which offers features like far-field microphones and specialist software which are great. But for most regular needs this might be overkill.
This best digital voice recorders guide will have something for you and it's also worth looking at the best voice recording software to make sure you get the most out of your choice.

Best Digital Voice Recorders: How Do They Work?
Every sound you’ve ever heard starts with vibrations in the air. These vibrations move through the air like waves, so they are aptly called sound waves. It’s like dropping a pebble into a puddle and watching the ripples move outward from the center.
These sound waves move at various speeds, which is why we hear different tones. For example, when you hit the lowest key on a piano, the low A, you create a ripple of sound waves that move up and down at 27.5 cycles per second, which is measured in hertz (Hz). When you hit the highest key, a high F, sound waves ripple out at 4,186 cycles per second.
Analog technology, such as records, captures a representation of these sound waves on physical media, and those waves are replicated when played back through an analog player. While records and record players have become popular again, analog devices aren’t very practical for recording on the fly.
To create a digital representation of a sound wave, a voice recorder picks up the audio with a microphone that converts the sound to an analog electric signal. The analog electric signal runs into an analog-to-digital converter (ADC). The ADC then converts the analog signal into a digital signal using pulse-code modulation or linear pulse-code modulation. In this process, the various points on the sound wave are given numerical values. When put next to each other on a graph, you can see the sound wave. A digital file might contain a lot of data, but you can write it to a hard drive or SD card, both of which can fit thousands of these files.
To play the recorded digital audio file, the reverse happens. The digital signal is converted to an analog electric signal that is sent along a wire connected to a speaker. The signal makes the speaker vibrate, which causes the air to vibrate, recreating the sound waves you originally heard.
Important Features in Digital Voice Recorders
Beyond audio fidelity, there are myriad other features to consider when choosing a digital voice recorder. When you know what features are available and which ones you need, you have the best chance of finding a quality recorder that fits your budget:
Most digital voice recorders fall under one of two categories: those meant for amateur or casual users and those made for professionals. If you fall under the former category – say, if you’re a student looking to record your professors’ lectures – a simple lower-end model is more than sufficient. There are plenty of recorders that focus on recording audio over creating high-quality audio files.
However, if you want to record your latest album of guitar songs or your voice acting portfolio, it’s critical you invest in a high-end recorder, as they create better sounding audio files. More expensive recorders are more powerful, have more customization options and sound better during playback.
Smaller voice recorders last about eight hours per charge, depending on what you record and which settings you use. This is more than enough time to record a lecture or a few short audio clips. Most recorders have decent standby capacity as well, so you don’t have to constantly charge them or replace the batteries often.
For light users, storage isn’t really an issue. However, if you record frequently or capture large, high-quality files, you need a device that has lots of internal storage or supports large SD cards. If you buy a recorder with insufficient storage, you’ll have to constantly delete old files, which is a hassle.
Size & Weight
Some of the recorders we tested are small enough to fit in your backpack, purse or even your front pocket. These small recorders won’t weigh you down should you have to lug them around all the time, and they aren’t conspicuous. However, they are typically lower-end models with fewer features.
Larger recorders are heavier and harder to maneuver, especially if you have microphones plugged into them. Consider how mobile your recorder needs to be and how much storage space you have before you buy.
Ease of Use
Smaller, lower-end recorders are all generally easy to use – spend five or 10 minutes reading their user manuals or tinkering with them, and you can find all the menus and features you’ll probably ever need to use. Higher-end recorders are much more complicated. They have lots more features and usually come with thick user manuals that take quite some time to read. You likely won’t be able to use a professional-quality recorder without first reading a good portion of the manual.
Audio fidelity is the overall accuracy of the sound as represented by the digital recording. Audio fidelity of a digital audio recording largely depends on the sampling rate and the bit depth. Since most people hear with two ears, mono and stereo recording can also affect fidelity.
The sampling rate is the number of times per second audio is recorded. It helps to imagine it like a video camera, which generally takes 24 still-frame images each second. When you view those still frames one after the other in quick succession, you see movement. When these auditory samples are played one after another, you hear intelligible sound.
Most digital voice recorders sample audio with a 44.1kHz or 48kHz rate. The highest-fidelity handheld recorders sample as high as 96kHz. However, humans can’t process sampling rates over 50kHz in a meaningful way, so a 96kHz sampling rate is overkill in most situations.
The bit depth is a measure of the bits of information in each sample. For example, audio recorded on a CD has a bit depth of 16-bits per sample, which is the same as most digital voice recorders. The bit depth determines the amplitude of the sound wave. A higher bit depth means there is a greater dynamic value between the loudest part of the sound wave and quietest part of the sound wave. Your smartphone records audio at 8 bits per sample, while the highest-fidelity digital audio recorders have 24-bit depths.
The difference in these recordings is the dynamic potential between loudest sound wave and the quietest sound wave. Imagine recording a roundtable meeting – the person sitting closest to you will sound the loudest, and the person sitting furthest from you will sound the quietest. The bit depth helps interpret how noticeable that volume difference was when you recorded it. As such, it is less important in situations where audio fidelity is not a priority.
In some cases, a lower bit depth with a high-pass filter, which removes unwanted frequencies, is ideal. For example, recording a lecture typically only requires enough fidelity to be able to clearly hear what your professor is saying. In fact, too much fidelity could result in picking up unwanted noise – whispers, chatter, pages being turned, etc.
Mono or Stereo?
Handheld digital recorders either record in mono or stereo. Mono recordings are made on one track, typically with one microphone. This means that when you listen to the track with headphones, you hear an equal mix on the left and right side. Digital voice recorders that record in stereo must have two microphones, which means they tend to cost more than mono recorders.
The difference between mono and stereo recording is depth. Stereo sound is more true to life because it is how your ears are designed to hear, similar to how two eyes provide vision depth a single eye cannot. For example, if your professor roams around the classroom during a lecture, with a stereo recorder you can identify where they were in the room at any given time. With a mono recording, you only hear fluctuations in the volume of the professor’s voice as they move away from and closer to the recorder.
Most stereo digital audio recorders have their microphones set up in an XY configuration – the microphone on the right is angled to the left side and vice versa. Some allow you to adjust the directions of the microphones so you can record audio with an AB configuration, where the microphones are parallel, or an ORTF configuration, where the microphones are directed away from each other.
Each microphone configuration creates a different stereo image. The XY configuration records sound with the least depth, as the microphones overlap each other. This emphasizes the middle of the mix and is best for recording a main source head on while picking up others on either side. The AB configuration provides more depth by de-emphasizing the center. For the widest stereo image, the ORTF configuration focuses almost entirely on separating the left and the right microphones with very little overlap.
