(December 2016) () MPEG-1 or MPEG-2 Audio Layer 2.mp2 audio/mpeg, audio/MPA Initial release 1993; 24 years ago ( 1993) Type of format Audio compression format, Contained by, Website MPEG-1 Audio Layer II or MPEG-2 Audio Layer II ( MP2, sometimes incorrectly called Musicam or MUSICAM) is a defined by ISO/IEC 11172-3 alongside and (MP3). While is much more popular for and applications, MP2 remains a dominant standard for audio broadcasting. See also: • MP2 is a, which means that compression takes place in the with a low-delay filter bank producing 32 frequency domain components. By comparison, MP3 is a with hybrid filter bank, which means that compression takes place in the after a hybrid (double) transformation from the time domain. • MPEG Audio Layer II is the core algorithm of the MP3 standards.

MPEG-1 Audio Layer II or MPEG-2 Audio Layer II is a lossy audio compression format defined by ISO/IEC 11172-3 alongside MPEG-1 Audio Layer I and MPEG-1 Audio Layer III (MP3). While MP3 is much more popular for PC and Internet applications, MP2 remains a dominant standard for audio broadcasting. This chapter describes two different methods for installing the packages needed to playback most multimedia formats - including MP3, DVDs etc., with Dragon (video) and Amarok (audio). You can use manual 1-click installation or use the command line - whichever method you prefer. By default only free, open, non-patent.

All psychoacoustical characteristics and frame format structures of the MP3 format are derived from the basic MP2 algorithm and format. • The MP2 encoder may exploit inter channel redundancies using optional 'joint stereo'. • Like MP3, MP2 is a perceptual coding format, which means that it removes information that the human auditory system will not be able to easily perceive. To choose which information to remove, the audio signal is analyzed according to a psychoacoustic model, which takes into account the parameters of the human auditory system. Research into has shown that if there is a strong signal on a certain frequency, then weaker signals at frequencies close to the strong signal's frequency cannot be perceived by the human auditory system.

This is called frequency masking. Perceptual audio codecs take advantage of this frequency masking by ignoring information at frequencies that are deemed to be imperceptible, thus allowing more data to be allocated to the reproduction of perceptible frequencies. • MP2 splits the input audio signal into 32 sub-bands, and if the audio in a sub-band is deemed to be imperceptible then that sub-band is not transmitted.

MP3, on the other hand, transforms the input audio signal to the frequency domain in 576 frequency components. Therefore, MP3 has a higher frequency resolution than MP2, which allows the psychoacoustic model to be applied more selectively than for MP2. So MP3 has greater scope to reduce the bit rate. • The use of an additional tool, and higher frequency accuracy (due to the larger number of frequency sub-bands used by MP3) explains why MP3 does not need as high a bit rate as MP2 to get an acceptable audio quality.

Conversely, MP2 shows a better behavior than MP3 in the time domain, due to its lower frequency resolution. This implies less codec time delay — which can make editing audio simpler — as well as 'ruggedness' and resistance to errors which may occur during the digital recording process, or during transmission errors. • The MP2 sub-band filter bank also provides an inherent ' concealment' feature, due to the specific temporal masking effect of its mother filter.

This unique characteristic of the MPEG-1 Audio family implies a very good sound quality on audio signals with rapid energy changes, such as percussive sounds. Because both the MP2 and MP3 formats use the same basic sub-band filter bank, both benefit from this characteristic.

Applications of MP2 [ ] Part of the and standards. Layer II is commonly used within the broadcast industry for distributing live audio over satellite, ISDN and IP Network connections as well as for storage of audio in digital playout systems. An example is 's programming distribution system. The Content Depot distributes MPEG-1 L2 audio in a Broadcast Wave File wrapper. MPEG2 with RIFF headers (used in.wav) is specified in the RIFF/WAV standards.

As a result, Windows Media Player will directly play Content Depot files, however, less intelligent.wav players often do not. As the encoding and decoding process would have been a significant drain on CPU resources in the first generations of broadcast playout systems, professional broadcast playout systems typically implement the codec in hardware, such as by delegating the task of encoding and decoding to a compatible soundcard rather than the system CPU. All players in countries contain stereo MP2 decoders, making MP2 a possible competitor to in these markets.

DVD-Video players in countries are not required to decode MP2 audio, although most do. While some store audio in MP2 and many consumer-authored DVDs use the format, commercial DVDs with MP2 soundtracks are rare. MPEG-1 layer 2 is the standard audio format used in the and formats (VCD and SVCD also support variable bit rate and as added by MPEG-2). MPEG 1 layer 2 is the standard audio format used in the standard for set-top boxes. MPEG 1 layer 2 is the audio format used in camcorders. MP2 files are compatible with some.

Naming and extensions [ ] The term MP2 and.mp2 usually refer MPEG-1 Audio Layer II data, but can also refer to MPEG-2 Audio Layer II, a mostly backward compatible extension which adds support for, encoding, and additional sampling rates, defined in ISO/IEC 13818-3. The abbreviation MP2 is also sometimes erroneously applied to video or MPEG-2 audio. See also [ ] • • • • • • • originally MP2-based, with numerous improvements Notes [ ].

I have several audiobooks (and a few mp3 tunes) that I can't get Winamp to play. Oddly, though, IrfanView plays it just fine. I'd rather use Winamp, though. I attempted to research it but couldn't find an answer. I tried at first downloading lots of codecs and then finally unintalled Winamp completely and reinstalled it with no extra codecs. Still nothing.

When I right click in Windows 7 (64 bit) and read 'properties' I see it is an MPEG Layer 3 Audio File. File info in Winamp says this: Payload Size: 9356256 bytes Header found at: 27284 bytes Length: 2339 seconds MPEG-2 layer 3 32 kbps, approx. 89964 frames 22050 Hz MonoI've tried to rename the file.wav,.m4a, mpeg. I was hoping someone else who knew more would respond by now. Hopefully someone still will. I suggested VLC b/c i figured it would play it, it seems capable of playing almost anything.

But also b/c i thought it might be able to identify exactly what codec is needed. Gspot is supposed to do the same. Ffdshow are codecs you can download, but honestly, i'm somewhat out of my depth here.

Bhulekh Software Download. Maybe post some example files to 4shared and hopefully someone can tell you exactly what they are and whats needed to make em work in winamp. GSpot seems to think it's an MPEG-1 Video file (containing MPEG-2 Layer 3 audio), so renaming it with the.mpg extension should work.

Or you could even rename it to.mpa and add;MPA to the Extension List in Winamp >Prefs >Plugins >Input >DirectShow Decoder >config. Winamp should then use the same combination of DirectShow Splitters/Filters as GSpot to play it (MPEG-1 Splitter >ffdshow >ac3filter). Not sure why AC3Filter is being used though, unless you've got AC3Filter set to handle 'MPEG Audio' in: AC3Filter Config >System tab. EDIT I've just read the first post again.

Hmm, as suggested above, I think you need to upload a sample file for us to examine. If you've already tried renaming it to.mpeg and it didn't play, then renaming it to.mpga or.mpa probably won't work either. Winamp's in_mp3 should be able to play.mp3 files with mpeg-2 layer 3 audio. Re: 'Header found at: 27284 bytes' At a guess, there's something embedded at the beginning of the file (art or lyrics or similar) which could be causing the problem.
