Here we are after two months of work with the public release of: So I started to think: "I could develop this app, using some modern framework/programming paradigm I studied in the last months.In this way I have a chance to create my first macOS app and add some other interesting projects to my Github profile.and in this way I can work on a project where I don't have to launch the commands npm install or npm run build hundred times in a hour.". I want an app that a real Apple fag would be happy to use."□□. My next question was: "How is it possible that there's not a native macOS app? There are only cross platform/web solution. The attached picture frames that have the 0x00 "Other" type are discarded □. But the Media Nav Evolution system of my Renault Clio is able to read only attached picture frames inserted in the tag with a specific type, for example 0x03 "Cover (Front)", that is the default type inserted by Mp3Tag. All this application set the byte to 0x00 that in the ID3 standard corresponds to the "Other" cover type. The problem is that iTunes and other native macOS "mp3 tagger" applications don't let the user modify the type of the attached picture. The type of picture is represented as a byte just after the MIME type in the attached picture frame of the ID3 standard. The fact is that the ID3 standard accept multiple types of attached picture for an mp3: front cover, back cover, icon, artist photo etc. Yep, a single byte could make a big difference □. So I opened with my favourite hex editor HexFiend an mp3 tagged with iTunes and another one tagged with Mp3Tag and I compared them. The only way to discover the reason behind this mystery was to compare an mp3 tagged with Mp3Tag with an mp3 tagged with one of the other applications. But then I started to ask myself: "What is doing Mp3Tag that the other native macOS application are not doing?". So I downloaded it and tried to tag some mp3. Then I found an app called Mp3Tag, a Windows app that runs on macOS using Wine. So I got back to my desk and I started to download some native macOS app that let the user edit what I discovered was called ID3 tag. What the hell is going on?!!?! □ The title and the album where displayed but the cover was not show on the screen. I saved them on a usb key and I went to my car to test them. So I sat in front of my MacBook Pro, I opened iTunes and I started to tag my mp3 files. This is exactly the moment where my journey into the development of ID3TagEditor and Mp3ID3Tagger started, but I was not yet aware of it □. I want to see the cover of the album for each mp3 I have!!!!!!!". I though: "Whoah this is very cool!! I need to start to fill my mp3 with all this information. I suddenly made a great discovery: some of my songs were displayed on the touchscreen with information about the album and they were displaying the cover of the album!!!!! □. So I prepared an USB key with some of my mp3 and I started to listen to them. One of the thing that caught my attention was the possibility to start to listen to my mp3 collection while I'm driving (on my previous car I had a standard cd player). This system has a 7'' touchscreen with map integration and a basic smartphone integration with Siri voice recognition and phone call support. One of its most interesting feature is its media entertainment system: the Media Nav Evolution system. It has been a big step forward on my previous car. After a lot of searches I finally decided to buy the Renault Clio 2017 1.5 dci. In this post I will talk about why I started to develop them. The first of a short series of post in which I describe my two open source project I published some times ago: ID3TagEditor and Mp3ID3Tagger.
