They should be available by default, but you can <a href="http://osxdaily.com/2012/01/16/enable-video-audio-encoder-in-mac-os-x/">enable the media encoders</a> if they aren’t visible in contextual menus for you.</p> <h2 style="font-size:1.2em;">Convert AIFF to M4A Easily from Mac OS X</h2> <ul> <li>Right-click the AIFF audio file and choose “Encode Selected Audio File”</li> <li>At the “Encode to MPEG Audio” window, pull down the Encoder menu and choose “iTunes Plus”, this will result in a 256kbps m4a file</li> <p><img src="http://osxdaily.com/wp-content/uploads/2012/01/encode-m4a-from-aiff.jpg" alt="Encode M4A Audio from AIFF Source" title="encode-m4a-from-aiff" width="516" height="212" class="aligncenter size-full wp-image-26645" /></p> <li>Change Destination if necessary, otherwise click on “Continue” and let the encoder do it’s work</li> <li>Look for the newly converted m4a file in the same directory as the origin AIF</li> </ul> <p>How long the conversion process takes depends entirely on the processing power of the Mac, but it’s always quick. Even on a slower 1.6GHz Core 2 Duo with 2GB of RAM, a 42mb AIF file was converted in about 30 seconds, and the entire process should be finished in less than two minutes as demonstrated in the video below.</p> <p>Other than greater compatibility and portability, the other benefit of encoding audio is file size reduction. In this example, the AIFF audio file started off at 42MB but was shrank down to 7.8MB in a 256kbps M4A file, without losing any observable audio quality. </p> <p><iframe width="620" height="450" src="http://www.youtube.com/embed/RQ0MYA5qsa0?rel=0" frameborder="0" allowfullscreen></iframe></p> <p><strong>What About Mac OS X 10.6 Snow Leopard?</strong> If you’re not using Mac OS X 10.7 Lion, you have a few options. First is to use iTunes, which <a href="http://osxdaily.com/2010/05/01/convert-songs-to-mp3-aac-m4a-or-other-formats-in-itunes-9-1/">also has some encoding</a> and converting tools built into it at all versions, as we covered <a href="http://osxdaily.com/2010/10/16/convert-wav-to-mp3/">before</a>. The filetypes in iTunes are pickier and it’s not as flexible though. Another option is to use All2MP3, a free app that handles a wide range of audio conversion with. From <a href="http://osxdaily.com/2009/10/21/convert-wma-to-mp3-in-mac-os-x-for-free/">wma</a> to <a href="http://osxdaily.com/2010/07/16/flac-to-mp3-for-mac/">flac to mp3</a> and more, All2MP3 gets it done, although you won’t get the elegance of audio conversion directly from the Finder or the convenience of not having to download another app.</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/vYEnnNr0LzwmqyQuUTZNGuWMo3Y/0/da"><img src="http://feedads.g.doubleclick.net/~a/vYEnnNr0LzwmqyQuUTZNGuWMo3Y/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/vYEnnNr0LzwmqyQuUTZNGuWMo3Y/1/da"><img src="http://feedads.g.doubleclick.net/~a/vYEnnNr0LzwmqyQuUTZNGuWMo3Y/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=xSS6PSqNG1g:bMDhiTxRijM:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=xSS6PSqNG1g:bMDhiTxRijM:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=xSS6PSqNG1g:bMDhiTxRijM:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=xSS6PSqNG1g:bMDhiTxRijM:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=xSS6PSqNG1g:bMDhiTxRijM:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=xSS6PSqNG1g:bMDhiTxRijM:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=xSS6PSqNG1g:bMDhiTxRijM:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/xSS6PSqNG1g" height="1" width="1"/> View the full article
