They also differ in age, standards, and intended use, as well as in the meaning of the terms &quot;MP3 player&quot; and &quot;MP4 player.&quot;.<\/p>\n<p> To sum it up<\/p>\n<ul>\n<li> <strong>MP3<\/strong> \u2014 is a lossy audio compression format - the file contains only audio.<\/li>\n<li> <strong>MP4<\/strong> \u2014 is a container: it can contain video (for example, H.264, H.265), audio (most often AAC), subtitles and images.<\/li>\n<li> The MP3 format was created in the early 1990s, and MP4 is a 2003 standard (ISO\/IEC 14496-14).<\/li>\n<li> For music, MP3 is enough, for movies you need MP4 (or another video format).<\/li>\n<\/ul>\n<h2> MP3 and MP4 \u2013 the main difference<\/h2>\n<p> The names sound similar, but they describe different things. <strong>MP3<\/strong> (MPEG-1\/MPEG-2 Audio Layer III) is <strong>audio coding format<\/strong> , which determines how a recording is compressed to reduce its size. An .mp3 file contains one audio track and metadata such as the song title and artist.<\/p>\n<p> <strong>MP4<\/strong> (MPEG-4 Part 14) is <strong>container format<\/strong> , or &quot;box,&quot; which can contain multiple streams simultaneously: an image, one or more audio tracks, subtitles, images (such as cover art), and metadata. The container itself doesn&#039;t determine quality; it depends on the codecs used to store the content.<\/p>\n<h2> What is MP3?<\/h2>\n<p> The MP3 format was developed at the Fraunhofer Institute in Germany by a group of researchers led by Karlheinz Brandenburg. The standard was approved in 1991 and published as ISO\/IEC 11172-3 in 1993. It uses <strong>lossy compression<\/strong> : An algorithm that removes parts of the signal that most listeners won&#039;t hear anyway, resulting in a file many times smaller than an uncompressed recording.<\/p>\n<p> The quality of MP3 files primarily depends on <strong>bitrate<\/strong> . The MPEG-1 standard defines values from 32 to 320 kbps\u2014the higher the value, the better the quality and the larger the file size. A popular value is 128 kbps, and higher bitrates are typically chosen for listening on high-quality equipment. The last US patents on MP3 expired in 2017, so the format is now freely available.<\/p>\n<h2> What is MP4?<\/h2>\n<p> MP4 is part of the MPEG-4 family of standards described in <strong>ISO\/IEC 14496-14:2003<\/strong> . It is based on Apple&#039;s QuickTime format. It most often includes video encoded in <strong>H.264\/AVC<\/strong> or <strong>H.265\/HEVC<\/strong> (increasingly also AV1), and audio in <strong>AAC format<\/strong> , which was developed as a successor to MP3.<\/p>\n<p> The MP4 container has several extensions: <strong>.mp4<\/strong> (usually video), <strong>.m4a<\/strong> (audio only), <strong>.m4v<\/strong> (video), <strong>.m4b<\/strong> (audiobooks) and <strong>.m4r<\/strong> (ringtones). Thus, the .m4a file is the closest analogue to MP3 in the MP4 world. Interestingly, the MP4 container can also store MP3 audio, although this is rarely used in practice.<\/p>\n<h2> MP3 vs. MP4 Comparison Chart<\/h2>\n<table>\n<tbody>\n<thead>\n<tr>\n<th> Characteristic<\/th>\n<th> MP3<\/th>\n<th> MP4<\/th>\n<\/tr>\n<\/thead>\n<\/tbody>\n<tbody>\n<tr>\n<td> <strong>What&#039;s happened<\/strong><\/td>\n<td> Audio coding (compression) format<\/td>\n<td> Multimedia container<\/td>\n<\/tr>\n<tr>\n<td> <strong>Content<\/strong><\/td>\n<td> Audio only + metadata<\/td>\n<td> Video, audio, subtitles, images, metadata<\/td>\n<\/tr>\n<tr>\n<td> <strong>Standard<\/strong><\/td>\n<td> MPEG-1\/2 III Audio Layer (ISO\/IEC 11172-3)<\/td>\n<td> MPEG-4 Part 14 (ISO\/IEC 14496-14)<\/td>\n<\/tr>\n<tr>\n<td> <strong>Start<\/strong><\/td>\n<td> Approved in 1991.<\/td>\n<td> 2003 Standard<\/td>\n<\/tr>\n<tr>\n<td> <strong>Typical codecs<\/strong><\/td>\n<td> MP3 (the codec itself)<\/td>\n<td> H.264, H.265, AV1 (video); AAC (audio)<\/td>\n<\/tr>\n<tr>\n<td> <strong>Extensions<\/strong><\/td>\n<td> .mp3<\/td>\n<td> .mp4, .m4a, .m4v, .m4b, .m4r<\/td>\n<\/tr>\n<tr>\n<td> <strong>Typical use<\/strong><\/td>\n<td> Music, podcasts, audiobooks<\/td>\n<td> Movies, phone recordings, videos from the Internet<\/td>\n<\/tr>\n<tr>\n<td> <strong>file size<\/strong><\/td>\n<td> Smaller size (audio only)<\/td>\n<td> Usually larger in size (the image takes up more space).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2> MP3 player vs. MP4 player<\/h2>\n<p> There are devices on the market called &quot;MP3 players&quot; and &quot;MP4 players.&quot; These are trade names, not technical terms. <strong>MP3 player<\/strong> used for listening to music and usually does not have a screen for playing video or has only a small display. <strong>MP4 player<\/strong> It has a screen and can play videos, as well as, of course, MP3 files.<\/p>\n<p> Note: The term &quot;MP4 player&quot; does not guarantee support for all .mp4 files.

Converting MP3 to MP4 will not improve audio quality\u2014the file will only receive a new container, and if it contains an image, you&#039;ll need to add one (for example, a static graphic).<\/p>\n<h2> Frequently Asked Questions (FAQ)<\/h2>\n<p> <strong>Is MP4 an improved version of MP3?<\/strong><\/p>\n<p> No. These are not successive versions of the same format. MP3 is an audio format, while MP4 is a container that can store video, audio, and subtitles. MP3&#039;s successor in audio compression is likely AAC, which is often stored in the MP4 container (.m4a).<\/p>\n<p> <strong>Can an MP4 file contain only audio?<\/strong><\/p>\n<p> Yes. MP4 audio files typically have the .m4a extension (or .m4b for audiobooks). They most often contain AAC audio.<\/p>\n<p> <strong>How to convert MP4 to MP3?<\/strong><\/p>\n<p> Simply extract the audio track using a media converter (such as VLC) or an online tool and save it as an MP3. Since this is lossy encoding, choose a high bitrate, such as 192-320 kbps.<\/p>\n<p> <strong>Does the MP3 player play MP4 files?<\/strong><\/p>\n<p> It usually doesn&#039;t play video. Some players support .m4a files (AAC audio in an MP4 container). For more information, please refer to your device&#039;s specifications.<\/p>\n<p> <strong>Which format provides better sound quality \u2013 MP3 or MP4?<\/strong><\/p>\n<p> This depends on the codec and bitrate, not the container itself. AAC audio saved in MP4 with the same bitrate usually sounds at least as good as MP3, but a high-bitrate MP3 file can sound better than MP4 audio saved with a very low bitrate.<\/p>\n<h2> See also<\/h2>\n<ul>\n<li> What is the difference between a mobile phone and a smartphone?<\/li>\n<li> What is the difference between an e-book and an audiobook?<\/li>\n<li> What is the difference between a webcam and a digital camera?<\/li>\n<li> What is the difference between Intel Core i3 and i5 processors?<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>MP3 differs from MP4 in that MP3 is an audio-only format, whereas MP4 is a multimedia container,<\/p>","protected":false},"author":1,"featured_media":176101,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[67,20],"tags":[70],"class_list":["post-176100","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-vopros-otvet","category-fakty","tag-chem-otlichaetsya"],"_links":{"self":[{"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/posts\/176100","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/comments?post=176100"}],"version-history":[{"count":1,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/posts\/176100\/revisions"}],"predecessor-version":[{"id":176102,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/posts\/176100\/revisions\/176102"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/media\/176101"}],"wp:attachment":[{"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/media?parent=176100"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/categories?post=176100"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bukvaved.top\/en\/wp-json\/wp\/v2\/tags?post=176100"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
