Digital audio is a technology that uses digital means to record, store, edit, compress or play sound. It is a brand new sound developed with the development of digital signal digital audio processing technology, computer technology and multimedia technology. Means of treatment. The main areas of application for digital audio are music post production and recording. The storage of computer data is accessed in the form of 0, 1. The digital audio is to first convert the audio file, and then convert these level signals into binary data, and convert the data into analog power when playing. The flat signal is sent to the horn to broadcast, and the digital sound is essentially different from the sound in the general tape, radio, and television. In comparison, it has the characteristics of convenient storage, low storage cost, no sound distortion during storage and transmission, and easy editing and processing. Common digital audio interfaces include I2S interface, PCM interface and SPDIF interface. Here is a brief introduction. 3â„4 I2S interface: It can only transmit digital audio in mono or two-channel stereo, and the data format is PCM format. The interface is derived from three categories: left-justified format, right-aligned format, and I2S format. I2S time difference performance is better than SPDIF, suitable for short-distance communication. 3â„4 PCM interface: Also called DSP mode audio interface. It is generally used to transmit digital audio in mono or two-channel stereo, but theoretically it can also transmit multi-channel digital audio. The data format is PCM format. 3â„4 SPDIF interface: SPDIF (Sony Phillips Digital Interface) SONY, PHILIPS digital audio interface. Its transmission carrier has two kinds of coaxial and optical fibers, and the latter has stronger anti-interference ability. SPDIF can transmit PCM streams and also transmit surround sound compressed audio signals such as Dolby Digital and DTS. The PCM stream is the original, uncompressed audio signal, and the Dolby Digital and DTS are also derived from the PCM stream. Digital audio applications are not very extensive, but it has its own domain that is the recording of music and a post-production of the song. Digital audio can convert its audio files first, then convert the signals belonging to the audio files into a unique data for saving. When playing the converted music, you can change the previous data. A simulated signal is then output by a loudspeaker. The digital sound thus formed has the essential difference between the sound on the radio, the speaker, and the sound on the TV. In this case, the digital sound has the convenience of audio storage, and the audio storage has the advantage of low cost. There are significant changes in the file during transmission, such as the file is not damaged, and there are some features that are very convenient during editing and processing. Xiaobian will tell you a few basic knowledge of digital audio, including sampling rate, compression ratio, bit rate and quantization. The higher the percentage of the sample rate, the better the sound quality within the digital audio. The compression ratio is the ratio of the file to the size of the file before it is compressed. The bit rate is a reference performance indicator that indicates the bit value of digital audio at a particular time. Quantization is to describe the data of digital sound. The basic knowledge of these digital audio contains a lot of information about digital audio. I hope that if you want to know more about the basic knowledge about digital audio, you should check the information well.
