Imagine the quietest whisper and the loudest bang in a concert. Dynamic Range: Key Differences Between Bitsīut look at this difference in terms of dynamics: The difference between 16-bit and 24-bit sounds huge - at least when you look at the number of available levels. Whereas 24 bits can contain over 16 million (16,777,216) unique levels. Computers are able to manage entire strings of these at a time.ġ6 bits states that there are 16 binary digits in a word, so each digit in a string represents either a value of 0 or 1.Ģ4 bits states there are 24 digits in a word, and this idea goes the same for higher-numbered bits.Ī sample recorded at 16 bits can, therefore, contain over 65,000 (65,536) levels. In the computing world, strings of binary digits or bits are used to describe anything a computer does. Let’s talk music geek for a bit, shall we? All About Bits And that’s why we have something called “sampling” in music. What these actually mean is that in practice, digital recording can never be an exact representation of the original signal but rather a “sample” of it. Speed of sampling (sample rate which is expressed as a number of samples taken during 1 second).It’s important to understand now that sampling (or digital capturing) is essentially a process that creates a digital ‘snapshot’ of an analog signal (that’s constantly varying). It then converts the bitstream back to voltage or current. When we want captured bit audio data, we need to send the information to a digital-to-analog converter (DAC). This audio interface can be processed and stored as binary numbers. Your audio interface (e.g., portable recorder, sound card, hardware sampler, etc.) uses a special analog-to-digital converter (ADC) to convert analog electrical signals such as voltage or current into a digital bitstream. Bit Depth Guide for Dummies: Breaking Down the Bitsįun fact: Analog source signal (straight curve) is converted to digital representation that can then be processed into the digital domain.
