Xiaobian to share with you what is the extension of the waveform file format in the computer, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

The waveform file is a digital file obtained by collecting the mechanical vibration of all kinds of sound, and its extension is ".WAV". WAV format is a sound file format developed by Microsoft. It is the earliest digital audio format. It supports many compression algorithms, supports a variety of audio digits, sampling frequencies and channels, and adopts 44.1kHz sampling frequency and 16-bit quantized digits.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Waveform file is a digital file obtained by collecting mechanical vibration of all kinds of sound. The characteristic of waveform file is that it can save and reproduce the effect of the original sound source. it is often used for the recording of natural sound such as music and songs, but the storage space of the file is relatively large.

The waveform sound file has the extension ".wav".

WAV format is a sound file format developed by Microsoft, also known as waveform sound file. It is the earliest digital audio format and is widely supported by Windows platform and its applications. WAV format supports many compression algorithms, supports a variety of audio digits, sampling frequencies and channels, and uses 44.1kHz sampling frequency and 16-bit quantized digits, so the sound quality of WAV is similar to that of CD.

WAV format files can record a variety of mono or stereo sound information, and can ensure that the sound is not distorted. But the fatal disadvantage of WAV files is that they take up too much disk space (about 12 megabytes of disk space per minute of music).

It conforms to the resource interchange file format (RIFF) specification, is used to save audio information resources on the Windows platform, and is widely supported by the Windows platform and its applications.

Wave format supports MSADPCM, CCITT A law, CCITT μ law and other compression algorithms, and supports a variety of audio digits, sampling frequencies and channels. It is the most popular sound file format on PC, but its file size is large and is often used to store short sound clips.

Scope of application:

Generally speaking, the larger the sample size (amount of information) and the higher the sampling frequency, the better the sound quality, but the more expensive the waveform audio is. Because the speech can be better restored by 8-bit 11.025KHz sampling, the waveform audio is generally suitable for the following situations:

1. The sound played is speech, and the music effect does not require too high the quality of the sound.

2. Need to load sound and other data from the CD-ROM CD-ROM drive at the same time, and the transmission of sound data can not monopolize the processing time.

3. When the sound data that needs to be stored in the PC hard disk is less than 1 point and the available storage space is sufficient.

The above is all the contents of the article "what is the extension of the waveform file format in the computer". Thank you for reading!
