Sample rate is the number of samples of audio taken per second and controls the frequency response of a recording. Now that you know the basics of digital audio formats, let's talk about audio resolution, and how it affects the quality of your recordings.Īudio resolution is determined by the sample rate and bit depth of the digital audio recording. Some formats use data compression to reduce the size of the file-more on that later. When a computer scans the code, it recreates the original audio signal. When we record audio in a digital format, like an MP3 or an audio file on a CD, the original signal is sampled, digitized and stored as binary code (1's and 0's). When we record audio in an analog format, like on a vinyl record or a roll of tape, the original audio waveform is stored directly on the medium. In this blog, we'll break down the differences between the most common audio file formats to help you determine which is best, including FLAC, WAV, MP3 and more.īefore we get too far along, let's talk about what an audio file format actually is. That's why it's important to make sure you're always using the best format for the job. But, using the right file format can have a big impact on your overall sound. From high-res FLAC files to compressed MP3s, it can be tricky to keep them all straight. ![]() In the audio world, we work with a lot of different file types.
