What is the file format of wav?

wav is an audio file format that can save high-quality audio data, divided into PCM format and non-PCM format. PCM format is a raw audio format that can save real audio signals. Non-PCM format is a lossy compression format that reduces file size by sacrificing some audio information. The most common non-PCM formats are WAV header and RF64. The WAV header format is an encapsulation standard developed by Microsoft for the Win operating system and can encapsulate audio data in various formats. The WAV header format of RF64 can save audio data larger than 2GB.

WAV is an audio file format, its full name is Waveform Audio File Format. It is divided into two types: PCM format and non-PCM format. PCM format is a raw audio format that can save real audio signals. The non-PCM format is a lossy compression format that reduces file size by sacrificing some audio information. The most common non-PCM formats are Adobe WAV header (wav header) and RF64.

WAV header is a storage standard that uses header information to describe audio data, including sampling rate, number of channels, bit rate and other information. The WAV header format was developed by Microsoft for the Windows operating system. Therefore, files in the WAV header format can be read correctly on the Windows operating system. In other operating systems, additional software or plug-ins may be required to support reading files in WAV header format.

Since the WAV header format is just an encapsulation format, it can encapsulate audio data in PCM format and other formats to form a WAV header format file. Therefore, in addition to audio data in PCM format, audio data in other formats can also be encapsulated into files in WAV header format.

WAV header format files are usually used to save high-quality audio data. Because it is not compressed, it can retain complete audio information. However, since it is not compressed, its file size is large and is not suitable for long-term recording or large-scale storage.

In addition to the WAV header format, there is also a WAV header format based on RF64. RF64 is a storage standard that can save audio data larger than 2GB. Compared with the traditional WAV header format, the main difference between the RF64 WAV header format and the traditional WAV header format is the way in which information such as sampling rate and channel number is described.

In short, WAV is an audio file format that can save high-quality audio data and is divided into PCM format and non-PCM format. Among them, the WAV header format is an encapsulation standard developed by Microsoft for the Windows operating system. It can encapsulate audio data in various formats. In addition to the WAV header format, there is also a WAV header format based on RF64, which can save audio data larger than 2GB.
