audio wav

WAV files are resource Interchange file formats (RIFF), including a number of named blocks that contain header information, such as a sound sampling format, or data (such as the sample itself). The Win API provides functions such as turning off Fiff files, finding blocks, and so on. The names of these functions begin with "Mmio". The DirectSound API does not include methods for writing WAV files. However,

bitrate, refers to the file is a bit rate from beginning to end. Compared to VBR and ABR, it compresses the file volume is very large, but the sound quality will not be significantly improved.Lossy and LosslessAccording to the process of sampling and quantification, the audio coding can only achieve the infinite close to the nature signal, at least the current technology is not likely to be exactly the same. This is because the signals in nature are

This article is mainly about Avaudioplayer, the other two see related articles. Avaudioplayer in the avfoundation frame, so we're going to import avfoundation.framework. The Avaudioplayer class encapsulates the ability to play a single sound. The player can initialize with Nsurl or nsdata, note that Nsurl can not be a network URL and must be a local file URL, because the Avaudioplayer does not have the ability to play network audio, but we can use a l

Windows mCi (media control interface) Yes Windows Provides high-level and general control over multimedia devices. . It provides a set of device-independent functions and Command to effectively control multimedia devices. By using MCI, we can easily perform operations on multimedia without having to understand the working principle of multimedia devices and call the underlying function library, which greatly reduces the difficulty and burden of development. Here is a small example of a

Sometimes, we write the program need to play music, generally we will use the following ways: 1. Place music files in a specific directory, such as Sound,wav,music for the program to read and play; 2. Use resources to store music. Some people may also use this method, but most people might have to release the music files from the resources before they read the playback. The way I'm going to present today is to load the music files directly into memory

The first four articles, respectively, introduced the basic knowledge of audio development, how to capture a frame of audio, how to play a frame of audio, how to store and parse WAV file, it is suggested that interested small partners to read, this article focuses on how to encode and decode a frame of
