What audio file format does NOT use compression to reduce file size?
Wave, AIFF SND and many other formats are not compressed. Most of these are variations of a PCM (pulse code modulation) format.
What is the difference between mp2 m2v ac3 and a52?
Each audio format intended for DVD has different compression ratio and quality. There are three main types of audio: AC3 (Dolby Digital), PCM (uncompressed), and MP2 (MPEG Layer II). The most common quality of audio in DVD is 48hz (frequency), with Dolby Digital 5.1 (surround sound).AC3It's a Dolby Digital Audio. AC3 supports not only stereo, but also surround. Audio bitrate range: from 128Kbit/s to 384Kbit/s. 192Kbit/s is the most common bitrate.Surround sound must have at least 6 separate source channels. Taking a stereo or mono audio file and forcing it into Dolby 5.1 format will only waste space and provide no advantages.Pros: AC3 format has very good quality, surround sound support and very high level of compression. That's why the size of audio information is small.AC3 is the best format to use in DVDPCMCons: The main disadvantage of Uncompressed PCM (WAV or AIFF) audio format is size. It stores all audio information without compression. It's a recommended format for audio editing. Do not use PCM in final versions of DVD. Only leave it as PCM if final disc size is unimportant or if unusual distortion occurs from AC3 or MP2 compression. Common bitrate is 1536k.Pros: The main advantage of the PCM audio is excellent quality. With PCM you can preserve all audio frequencies (even outside the range of human hearing).MP2Another form of MPEG audio is MP2. Also known as MPEG Layer II and .mpa files. This format is not officially supported for NTSC video. If you have MP2 audio then do not recompress it to AC3, recompression may destroy the quality. So, leave it untouched. But if you have PCM uncompressed source, I definitely recommend to use AC3 instead of MP2. Common bitrate is 256Kbit/s.Pros: The main advantage of MP2 is good compression level and ease of audio conversion from SVCD or VCD.Cons: The main disadvantage of MP2 is not very good quality, and lack of support by all devices.
What is wma playback for psp?
WMA is windows proprietary audio format (windows media audio) - similar to mp3 but mp3 is usually the most common audio format used for music. Unless of course you use like Napster - wma files w/ drm.
What is an AVI file?
Audio Video Interleave (AVI) is a special case of Resource Interchange File Format (RIFF). AVI is defined by Microsoft. The .avi file format is the most common format for audio and video data on a computer. Audio content or video content that is compressed with a wide variety of codecs can be stored in an .avi file and played in Windows Media Player.

What is a MP3?
.mp3 is an audio file in the .mp3 format, as compared to .wav, etc. There are several different audio compression formats out there, some good, some worse. .mp3 seems the be one that most manufacturer's have agreed upon and hence, it's sort become a standard.
What compression formats are used for image?
Compression methods are used for images compression and most common compressions are JPEG which is lossy (you can lost some details or quality of image), LZW which is lossless, RLE and ZIP also lossless compressions.
What format do minidisc recorder save audio in?
Most minidisc recorders record in ATRAC3 plus format.
What is use of mp3 format?
MP3 is an audio compression file format. Music CDs you purchase from the store come in a wav format. If you use a CD Ripper like Express Rip, you can then save these songs onto your computer in an mp3 file format. Then you can use an audio CD burning program, like Express Burn, to create a music CD with MP3 file formats. Notice that your original CD will only hold about 12-15 songs and your new mp3 CD will hold around 100 songs. That is one of the many advantages of using an mp3 format.
Is a mpeg audio file the same as mp3?
Not necessarily. Although the most common MPEG audio format, there are also other standards, both previous to and successive to MP3. MPEG Audio Layer 1 (MP1) and MPEG Audio Layer 2 (MP2), as well MPEG-4 Part 3 could be classified as an "MPEG audio file."
What is the most common format for a report?
The most common format for a report is IMRAD: Introduction, Methods, Results and Discussion. Reports do not have to follow this format but this structure is standard.
Difference between mp1 mp2 mp3 mp4?
The MP1 audio file format used MPEG Layer 1 compression; that supported data rates of 384 kbps and was used primarily by Philips DCC Digital Compact cassettes; which has been, for the most part, replaced by the newer MP2 and MP3 formats.The MP2 audio file format used MPEG-1 Layer II compression to reduce the file size and for the most part, has mainly been replaced by the ubiquitous MP3 format. However; MP2 is still used for digital radio and digital television broadcasts.The quality of an MP3 file depends largely on the bit rate used for compression; common bit rates are 128 kbps, 160 kbps, and 192 kbps; higher bit rates result in higher quality files that also require more disk space. MP3 files are supported by most portable music players such as the Apple iPod; Microsoft Zune; and can also be played on the Amazon Kindle. Furthermore, MP3 audio music files can be played on virtually all home based sound systems.An MP3 file is limited with regard to the method of compression and can only store audio. MP4 on the other hand, can store video as well as audio. It can even store subtitles for a video file. Also, since MP4 is a container, it can store audio and video that have been compressed in different fashions. In fact, an MP4 file could be audio that has been compressed as an MP3.
