The version of ffmpeg available on Ubuntu is therefore outdated. m4a file extension, built to improve upon Apple’s proprietary AAC codec. However, Ubuntu's package maintainers just decided to switch to the Libav fork of FFmpeg and thus supply you with avconv instead of ffmpeg. In contrast, ALAC is a proprietary lossless audio compression technology created by Apple. Note: If you get a message about ffmpeg being deprecated, this is actually not the case – it's still an actively developed program. With Bash you could simply convert all files in a single directory as well: for f in *.m4a do ffmpeg -i "$f" -c:a flac "$.flac" done ![]() Possess more functions, such as conversion, editor, download. Just wait a few seconds, and the FLAC file will be converted to M4A. After selecting the output format, click 'Convert' to start converting FLAC to M4A. Like I said, I take that file and convert to AAC in iTunes. Click 'Profile' to choose M4A or any other format you like as the output format. Both of course are M4A files with the ALAC being a larger file. I have the option in my software of converting to ALAC or M4A.

In case you want to convert ALAC to FLAC, ffmpeg would be a good option, as it's free and available for almost every platform. Thus, when transcoding, the original version can't be reconstructed and you'd experience a loss of quality. Step 1 Upload m4a-file (s) Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page. MP3 or MPEG-4 AAC use various psychoacoustic techniques to achieve this. Lossless in a psychoacoustic sense would mean that you can't distinguish the original and the compressed version, yet they are very different from each other. In case you only use a "psychoacoustically" lossless codec, this is not possible. I don't think this applies to either FLAC or ALAC. through limited floating point precision in calculations. Step 1 Upload flac-file (s) Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page. The only error I could imagine would be an arithmetical one, e.g. Thus, they are equivalent and you should experience no loss when transcoding - even when transcoding multiple times. ![]() The reason for this is that the signal can always be reconstructed to its original form when a FLAC/ALAC file is decoded. Digital audio compressed by FLACs algorithm can. This may be unrelated, but I also note that the metadata is being manipulated, and when iTunes imports it after it has been converted by Switch, iTunes gives it a different name to that it previously had and also to what the dBpoweramp converted file is renamed to - iTunes renames it based upon the metadata to and gives it a filename of 1-01 xxxxx.m4a, 1-02 xxxxx.m4a or similar, whereas normally it would be 01 xxxxx.Yes, given that both are mathematically lossless, conversion is lossless too.
