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. When put next to each other on a graph, you can see the sound wave. In this process, the various points on the sound wave are given numerical values. The ADC then converts the analog signal into a digital signal using pulse-code modulation or linear pulse-code modulation. The analog electric signal runs into an analog-to-digital converter (ADC). 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. While records and record players have become popular again, analog devices aren’t very practical for recording on the fly. When you hit the highest key, a high F, sound waves ripple out at 4,186 cycles per second.Īnalog 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. 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). These sound waves move at various speeds, which is why we hear different tones. It’s like dropping a pebble into a puddle and watching the ripples move outward from the center. These vibrations move through the air like waves, so they are aptly called sound waves.
īest Digital Voice Recorders: How Do They Work?Įvery sound you’ve ever heard starts with vibrations in the air. Read our Sony ICD-BX140 review (opens in new tab).A great option for anyone on a budget that doesn't mind playback on the device. The MP3 quality comes in 128 kbps and 192 kbps options with up to 4,175 hours of storage and 28 hours of battery life from the AAA batteries.
Quality is decent with a low-cut filter helping cut out wind noise from that mono microphone. You will need to listen on the device though as there's no output option from the 4GB of onboard storage. For the low price you get a big screen with lots of data, easy to use buttons and a compact design with headphone port for private listening. The Sony ICD-BX140 is a top pick for a super budget friendly digital voice recorder from a big name reliable brand. Olympus VN-541PC: Best affordable voice recorder

This comes with AAA batteries, making it easy to keep fully powered with a quick swap if needed and you get multiple editing software options to pick from. Everything is recorded to SD card, up to 128GB, so you can get it at the highest quality without worry about space. You get XY and mid-side microphones with the recorder but there are four other options to buy for specific purposes. The mic controls are easy enough to use with gain variations tracked and EQ settings variable. This is good enough for professionals that want the best quality thanks to the high-fidelity microphones and four XLR/TLS inputs on this six track recorder. The Zoom H6 is one of the more expensive voice recorders on this list but that is pricey only relatively – in reality this is well priced when you consider how many pro-grade features this delivers.
