A song is the same, only rather than being a collection of frames, it’s a collection of samples of audio signals. A faster frame rate means the video moves from one frame to the next quicker, making for a smoother video.

Consider the fact that a video is a collection of stills, or frames, put together. The sample rate of an audio file is akin to the frame rate of a video file. Those waves that create sounds must be converted-digitized-using what are known as transducers, like microphones and amplifiers for example, which turn these soundwaves into electrical signals.Ī digital system can then record those electrical signals by “sampling” them. Without sounding too flowery, audio is simply vibrations or waves traveling through the air. When we talk about the quality of an audio file, we’re usually talking about sampling rate and bit depth.Īudio is, at its core, analog. Each digital audio format will offer different capabilities in terms of sampling rate, bit depth, and compression. Another important term when considering sound quality is “lossless” or contrarily, “lossy” audio. Obviously, the higher the quality the better, but with high fidelity audio can come issues with storage, as these files tend to be huge.Īudio quality is mostly measured by sample rate and bit depth, which we’ll summarize below. There are a few different factors that will impact the quality of an audio file. When you’re building your music library, you shouldn’t let storage limitations get in the way of sound quality, and here we’ll explore a few tips for making sure your music is heard the way it’s meant to be heard. Audio compression is a technique used to reduce file size, making it easier to store music, but with a reduction in file size comes a reduction in quality. Whether you’re a passionate listener or a passionate creator, you want to be sure that your music library offers the best possible quality for your favorite tracks.
