MP4 is a container format that can store both audio and video compressed in different formats, along with subtitles. It allows streaming over the internet and supports high quality audio and video playback. MP3 is an audio-only compression format that reduces file sizes while maintaining good sound quality. Unlike MP4, MP3 cannot store video or multiple audio/video formats. Both formats are commonly used for storing and sharing multimedia online and on mobile devices.
Audio formats
CDs were originally able to store more data than computer hard drives but hard drives now far exceed CD capacity. By 2007, over 200 billion CDs had been sold worldwide, though sales have declined as digital storage and distribution has increased. CD pros include not being able to crash and easy use, while cons are being scratchable and having a small storage capacity. MP3s use lossy compression to reduce file sizes but also reduce audio quality slightly. MP3 pros are small file sizes and wide compatibility, while the con is potential quality loss. WAV files are uncompressed and highest quality but also largest in size, with pros being quality and support, and cons being large file sizes and slow importing.
multimedia data and file format
This document discusses different types of multimedia data and file formats. It describes text, graphics, images, audio, video, and animation. For images, it discusses bits per pixel and compression formats like JPEG, JPG, and BMP. It explains how audio is digitized and compressed, with lossy and lossless algorithms. Video involves sampling frames at rates like 30 fps and uses compression. Animation shows series of pictures displayed rapidly. Common file formats are described like RTF, TIFF, MIDI, JPEG, and MPEG, which is used for video compression standards.
File format
Digital media comes in different file formats for images, audio, and video depending on the device and how the file will be used. Common file formats include JPEG, GIF, PNG for images and MP3, WAV, and AAC for audio. Video file formats include AVI, MP4, and MOV. File formats can vary in properties like file size, quality, resolution, and whether they are compressed or uncompressed. Compression reduces file sizes but also lowers quality, while uncompressed files are highest quality but largest in size. The appropriate file format depends on balancing quality needs with file size and device compatibility.
Multimedia data and file format
Multimedia data and information must be stored in a disk file using formats similar to image file formats. Multimedia formats, however, are much more complex than most other file formats because of the wide variety of data they must store. Such data includes text, image data, audio and video data, computer animations, and other forms of binary data, such as Musical Instrument Digital Interface (MIDI), control information, and graphical fonts. (See the "MIDI Standard" section later in this chapter.) Typical multimedia formats do not define new methods for storing these types of data. Instead, they offer the ability to store data in one or more existing data formats that are already in general use.
For example, a multimedia format may allow text to be stored as PostScript or Rich Text Format (RTF) data rather than in conventional ASCII plain-text format. Still-image bitmap data may be stored as BMP or TIFF files rather than as raw bitmaps. Similarly, audio, video, and animation data can be stored using industry-recognized formats specified as being supported by that multimedia file format.

3 multimedia elements - audio
There are three main types of audio file formats: uncompressed, lossless compression, and lossy compression. Lossless compression preserves all audio quality while reducing file size, while lossy compression permanently removes some audio information to greatly reduce file size. Common audio formats include WAV (uncompressed), lossless WMA, MP3 and AAC (lossy), and MIDI (event-based musical instrument data). Audio is digitized through sampling, with higher sampling rates and more bits per sample providing better quality but larger file sizes. Formats like WAV and AIFF store uncompressed audio, while MP3 and WMA use lossy compression to reduce file sizes.
Audio file format
The document discusses the MP3 file format. It describes MP3 as a standard technology for compressing audio files to around 1/12 their original size while maintaining sound quality. The format uses MP3 frames containing a header and data block in a sequence of elementary streams. Higher bitrates in MP3 files produce higher quality sound closer to the original recording, while lower bitrates can be used for less complex audio passages. Metadata tags are not defined in the MP3 standard and licensing of related patents varies by region.

It provides examples of common file extensions for Microsoft Office files, images, audio, video, Adobe files, fonts, programs and other file types. The extensions help identify the file type and what program can open it. Knowing file extensions is important for identifying computer viruses and understanding file structures.
Chapter 4 : SOUND
Sound is created by vibrations that travel through a medium like air as sound waves. It has two main characteristics - frequency determines pitch, and amplitude determines loudness. Digital audio involves sampling an analog sound wave into discrete numeric samples at a certain rate. MIDI data provides instructions for synthesizing music rather than storing actual sound samples. When adding audio to multimedia projects, the file format, playback capabilities, and intended function of the sound must be considered.
Audio And Image Files
Lossy compression removes invisible information from audio and video files to reduce file sizes, resulting in some loss of quality but still retaining the essential aspects. Lossless compression reduces file sizes by removing redundant data but does not degrade quality as it allows exact reconstruction. Common lossy audio and video formats include MP3, JPEG, and MPEG-4, while lossless formats include FLAC, PNG, and ZIP.
Multimedia systems and applications
The document discusses various multimedia file formats including RTF, TIFF, RIFF, MIDI, JPEG, AVI, MPEG, and EXIF.

DVD-ROMs allow for the distribution of movies and software, storing data for reading like CD-ROMs but with greater storage. MP3s compress audio files without significant quality loss using human hearing psychology. Wi-Fi enables wireless connections between devices like routers and MP3 players, allowing transfer of files like music over home networks. PVRs store TV programs on a hard drive so users can watch them later or download scheduled programs automatically in the future.
What is mp3
MP3 is a compressed audio file format that allows for near-CD quality sound in small file sizes, making it popular for storing and sharing music online and on portable players. It was developed in the early 1990s as part of the MPEG audio standards and became widely adopted as music sharing grew on the internet and peer-to-peer networks. Converting audio from a music CD to the MP3 format is called "ripping" and can be done using software like iTunes. While MP3s only support audio, MP4 is a more advanced format that can contain audio, video, images and text, making it a true multimedia format that may replace MP3 as devices increasingly support more media types.

CDs were originally able to store more data than computer hard drives but hard drives now far exceed CD capacity. By 2007, over 200 billion CDs had been sold worldwide, though sales have declined as digital storage and distribution has increased. CD pros include not being able to crash and easy use, while cons are being scratchable and having a small storage capacity. MP3s use lossy compression to reduce file sizes but also reduce audio quality somewhat. MP3 pros are small file sizes and wide compatibility, while a con is potential quality loss. WAV files are uncompressed to maintain high quality but have very large file sizes, making them good for mastering but worse for storage and importing multiple files.

CDs were originally able to store more data than computer hard drives but hard drives now far exceed CD capacity. By 2007, over 200 billion CDs had been sold worldwide, though their popularity is declining with other digital storage replacing them. While CDs don't crash and are easy to use, they can be scratched or broken and have limited storage. MP3s compress audio files to reduce size but also reduce quality, though they are compatible across platforms. WAV files provide the highest quality audio but take up large amounts of storage space. The document examines and compares the pros and cons of these different audio file formats.
Week12
MP3 files contain compressed music data that takes up less storage space. An MP3 ripper program is used to convert music files, such as those from CDs, into the MP3 format so they can be posted and shared online. Websites allow users to download MP3 files that have been created through the ripping and compression process.
How MP3 Music Files
MP3 files work by compressing standard audio files from CDs, which have a bitrate of around 1411kbps, down to around 128kbps using the MPEG Audio Layer-3 format in order to make the files smaller and able to be stored on devices like MP3 players. A ripper application is used to extract the audio from music CDs and convert it to the compressed MP3 format without losing audio quality. The resulting MP3 files can then be played on MP3 players and other digital audio devices.
Week12
MP3 files allow listening to music on computers and digital audio players by compressing digital audio into a smaller file size without significant quality loss, making the format widely used. The encoder converts audio signals into MP3 format using algorithms that compress the file. Ripper software extracts audio from CDs and DVDs and converts it to MP3 files while maintaining sound quality. Copyright protection prevents illegal copying of MP3 files.
Audio file format
An audio file format is a file format for storing digital audio data on a computer system. There are three main types of audio file formats: uncompressed, lossless compression, and lossy compression (like MP3 and AAC). Examples of common file extensions include .wav, .mp3, .m4a, and .ra.
Mp3
MP3 is a digital audio format that compresses music files to about one-twelfth their original size without significantly reducing sound quality. It allows for small file sizes that make downloading and sharing music via email easy. Several free programs can play MP3 files on computers and dedicated MP3 players are still used by those who want affordable single-purpose devices or to prevent kids from breaking expensive phones.

This document discusses several technologies related to media convergence:
- Wi-Fi is a brand name that certifies interconnectivity between wireless LAN equipment.
- PVR is a video recorder that stores recordings on a hard disk, allowing for nonlinear editing and random access of content.
- MP3 is an audio file format that can compress sound files without significantly reducing quality, allowing music to be easily stored and shared from CDs to computers.
- USB is a serial bus standard introduced in 1996 to connect various peripherals to a host computer in a standardized way.
Week12_Web_Presentation
This presentation discusses how MP3 music files work. MP3 files are audio files that have been compressed using special algorithms to reduce their size to under 3MB while maintaining high quality. This allows music to be downloaded and shared online or stored on devices like MP3 players. While convenient for sharing music, MP3 files can raise issues regarding artists' copyrights.
