To capture a specific frequency, at least 2 samples are needed for each cycle … to measure both the upper and lower points of the sound wave. To record digital audio accurately, converters have to capture the entire human listening spectrum, which is between 20Hz – 20kHz.Īccording to the Nyquist-Shannon Sampling Theorem … The minimum of 44.1kHz is due to a mathematical principle known as … Normal sampling frequencies in professional audio range around: Logically, the end result is … better sound quality. It generates a much more accurate image of the analog signal. When taking more samples per second, the highest sampling rate: The results are not perfect, but they are good enough to generate excellent sound quality. The image is not accurate because in the intervals between samples, the converter basically has to guess what is happening. To convert the audio to binary code, they take tens of thousands of samples (samples) per second to make an “approximate” image of the analog waveform. Those that are integrated into the audio interfaces, which are usually seen in home studios. Those that are an independent device, which are normally seen in more advanced studies, or … In recording studios there are 2 types of digital converters: Then, as technology progressed, people discovered new ways to convert that information to other formats, including:īut in the end, with the rise of computers, digital audio ended up being the dominant format in the music production industry, since it allowed copying and transporting songs in a simple and free way.Īnd the device that made all that possible was … the digital converter. Originally, music information only existed as sound waves in the air. The Rise of the Digital Ageīinary code Although digital audio is the standard in today’s music … However, surprisingly, there are few people who really understand what it is about. Today … digital audio is the standard in almost all studios, both professional and amateur. The analog equipment of the past decades was being slowly but inexorably replaced …įor a new generation of audio interfaces and other digital equipment that was cheaper and easier to use. 62c-digital audio When recording at home began to become popular …
