Audio and Video for Your Web Site
Published in Tom Hutchison, Paul Allen, Web Marketing for the Music Business, 2013
Most audio files used by consumers for portable devices and Internet delivery are compressed. Compression is a means for reducing file size through discarding much of the duplicated data in the audio file. Consider the way “ditto” marks are used with text, and you get a basic analogy. The creation of the MP3 compression format for audio opened up the possibility for the first time of transferring music over the Internet. MP3 stands for MPEG (Motion Pictures Expert Group) Audio Layer III, and it is a standard for audio compression that makes any music file smaller with little loss of sound quality (although that’s debatable). Without this compression technique, one second of CD quality sound requires 1.4 million bits of data, so the average song in WAV format is extremely large, averaging around 50MB in file size. WAV is short for Waveform audio format, a Microsoft and IBM audio file format standard for storing audio on PCs. With MP3 compression, the file becomes one-twelfth its original size, at about 3 to 4 megabytes, depending on the bitrate.
Audio formats and data interchange

The RIFF WAVE (often called WAV) format is the Microsoft equivalent of Apple’s AIFF. It has a similar structure, again conforming to the IFF pattern, but with numbers stored in little-endian rather than big-endian form. It is used widely for sound file storage and interchange on PC workstations, and for multimedia applications involving sound. Within WAVE files it is possible to include information about a number of cue points, and a playlist to indicate the order in which the cues are to be replayed. WAVE files use the file extension ‘.wav’.
Quick Start: Your First Streaming Media File
Published in Joe Follansbee, Hands-On Guide to Streaming Media, 2006
Before we start encoding, it’s good to know something about file formats. The WAV format, pronounced, “wave,” is the standard format for storing audio signals on the personal computer. It was invented jointly by Microsoft and IBM in the 1980s. The format can store all types of sound with virtually any quality, including stereo. You can play .wav files with dozens of applications, including all streaming media players. These audio files use the file extension .wav.
SSVEP-based brain–computer interface for music using a low-density EEG system

Each BCI choice had one sound file associated with it. The audio output was played during the relax time. All sound files were stored in Waveform Audio File Format (WAVE or commonly known as WAV). Cross-fading was implemented to have smooth transitions between sound samples. Non-musical choices like remove, play, and shuffle had sound files that uttered the corresponding commands. The composition made by the user was stored as a WAV file on the computer, which can be played by any music player.

For the purpose of this work, we analyzed the audio obtained with the digital voice recorder. In total, we collected 12 audio recordings corresponding to each mother–child interaction (hereinafter referred to as AudioSession) with a minimum length of 8:08 min and a maximum length of 24:07 min. The dataset consists of 180:29 min of audio recordings. The audio was captured with a sampling rate of 44,100Hz in WAV format.
