What is the WAV format?
What are the advantages of the wav format?
WAV is a sound file format developed by Microsoft. It complies with the RIFF (Resource Interchange File Format) file specification and is used to store audio information resources on the Windows platform. It is widely compatible with the Windows platform and its applications. The format also supports various compression algorithms, such as MSADPCM, CCITT A LAW, and supports various audio numbers, sample rates, and channels. The standard format WAV file is the same as the CD format, with a sampling frequency of 44.1 kHz and a quantization number of -bit, so the quality of the sound file is almost the same as that of CD. a CD.
WAV uses three parameters to represent the sound, that is, the number of quantization bits, the sampling frequency and the number of channels, among them, the sampling frequency generally has three types: 11025Hz (11kHz), 22050Hz (22kHz) and 44100Hz (44kHz). ), and your WAV file occupies Capacity = (sample rate × sample bits × channel) × time / 8 (1 byte = 8 bits).
In terms of quality, we just said that WAV is almost equivalent to CD. But judging from the size of the above file, it is not difficult to find that the space occupied by WAV is too large. Therefore, for a long time before, WAV lost to MP3 and was not recognized by mass users. However, it is used as a standard file for recording in Windows.
