See |Exporting using an External Program] for more help. On Mac, you must give the full path to ffmpeg enclosed in quotes, instead of just "ffmpeg".įinally in the Export Audio dialog, add the M4A extension after the file name and dot. button, then enter the following command: Then export using the (external program) choice. On Mac, search for and download a standalone "ffmpeg" binary online. Instead, on Windows and Linux, install the optional FFmpeg library. You cannot export directly to Apple Lossless from the Export Audio dialog. Typically an Apple Lossless file is around half the size of an equivalent WAV file and more than three times the size of an equivalent AAC 256 kbps file. Like AAC it also uses files with the M4A extension.Īpple Lossless Encoder is quite similar to FLAC, producing larger files than AAC or MP3 but smaller than WAV. The app does not modify your iTunes library. Apple Lossless is, as the name suggests, Apple's size-compressed lossless codec. This iTunes export app let you preview and export metadata like: Title, Artist, Time, Album, Genre, File path, Kind, and Bitrate. For speech 128 kbps or even 64 kbps can be used as the bitrate if preferred.Īpple Lossless (Apple proprietary, lossless, smaller than WAV/AIFF)Īpple Lossless Encoding (sometimes referred to as ALAC - Apple Lossless Audio Codec) is also an Apple proprietary format. If you choose lossy formats (MP3 or AAC) the minimum bitrate setting you should use for music is 160 kbps, though 256 kbps is probably to be preferred - and in use on an iPod is unlikely to be distinguishable from WAV or AIFF (or Apple Lossless). The two main benefits are that you can fit many more songs into the device (for 256 kbps files you can fit about 10 times as many songs) and compressed files improve battery life, because disk reads are relatively heavy on battery power. There are several advantages to using a compressed format on iPods and iPhones. If you have plenty of storage space on your device or a relatively small music library you may wish to consider the larger lossless WAV or AIFF formats. MP3 should be considered if you think that in the future you may wish to switch to an alternative portable music player or phone. Then continue clicking OK until you are back to your iTunes library. Image of folder structure and explanation of different iTunes versions (turingtest2 post) - and AAC is the default format set in Apple Music/iTunes and the format Apple uses for audio files sold from the Apple Music/iTunes Store, so is the most obvious choice if you solely use Apple products. Make sure Channels says Stereo and Stereo Mode says Normal. You might need to spend more money on your show to host and store larger WAV files. A WAV file can be ten to eleven times larger than an MP3 file. These large files can affect your podcast budget and limit how listeners access your show. ITunes 9 : Understanding iTunes Media Organization - The high quality of WAV files comes at a costlarger file sizes. More on iTunes library files and what they do. If you put iTunes on the NAS I recommend you put the entire library on the NAS, not just media files. Putting iTunes on a NAS has been problematic for some. With WAV the only information you get is the filename. Then compare the results to determine if rendering is the problem. Try the following: Resample a fragment of your track in Live. Quicktime should play it normally though. Turn off the 'Sound Enhancer' in itunes preferences. WAV does not save track information as tags in the file so you will have to relabel all your files. For iTunes, there is an explanation why it sounds different. I strongly advise against using WAV format, particularly if you are rebuilding your library. Select one or more songs in your library, then choose File > Convert > Create format Version. In the Import Using pop-up menu, choose the format you want to convert songs to, then click OK to save the settings. If you intend to rebuild the library file from what is on the external you may wish to use a third party converter such as Max or XLD. In the iTunes app on your PC, choose Edit > Preferences, then click General. If you want to use iTunes with the new version on the external drive you may wish to do it that way so it all remains in the library file which you are also exporting. Of course using the above method will make a bunch of duplicates in your library. Exporting doesn't actually do anything with the music file, it only exports a text lising of the tracks. In iTunes 11 "Create." is in the File menu, not the Advanced menu.
