Feature Request - Lossy / Lossless versions of same song
« on: January 28, 2004, 12:33:39 pm »

So as per the suggestions of a number of people, I went ahead and started ripping my entire CD collection as APE rather than MP3 (so far I'm about 1/4 of the way through).  I'm now building a great library of my original CDs without any sort of compression artifacts.

This is great for my RAID array on my home PC, but now I've realized I want to transfer some songs to formats where space is at a bit more of a premium, such as CD-Rs for my MP3 car stereo, and to my PDA.  In the case of the PDA, I have to re encode the files as MP3 every time I transfer them over, which is a waste of time.  But if I want to create a CD-R with MP3s on it, I've got a lot of hoops to jump through.  I am now forced to re encode the APEs to a new directory, locate that directory, and then burn the files from there.

So here's my suggestion - for audio files there should be at least two separate files referenced in the library - a Lossy version and a Lossless version.  There could then be a function to automatically generate a lossy version of any file (choose your flavor, MP3 WMA, Ogg, etc), or select a pre-encoded file, and have it be referenced as part of the same library entry.  When burning files to disc or transfering to a player, you could then have the option of which version of the file you would like to transfer over.  While I've simplified my suggestion here, it hopefully would be possible to not just have 2 versions of the file, but many more, so that you could have a 32 kbps WMA file, a 128 kbps MP3, a 192 kbps Ogg and the original APE (or however you want to break it up to best suit your needs) for the same song, so that the you always have the correct format on hand for whatever situation / device you need it for.  When properties are changed, MC would update the tags automatically, so everything stays in sync.

Of course, this is perhaps too ambitious.  I've explored having both MP3 and APE versions of the song in the library and then filtering, but it is a management nightmare.  If I have a playlist that I want to transfer as MP3, I have no easy way of knowing which files I've converted, short of converting my entire collection to MP3 - it'd be nice if files could be converted as necesary.  Also, any changes made to the APE file (ratings, genre etc) will have to also be made separately to the MP3 file.  If anyone has any great ideas about how to better keep this sort of system in sync, I'd love to hear it, since so far it hasn't been working out too well for me.

As an interim measure, it'd be really nice if there were a one-step way to select files from a playlist and have the option to automatically re-encode them to MP3 before burning to disc, but ideally there should be an easy way to store these mp3 files once they've been encoded so that they're ready for the next time I need an MP3 version, thus my suggestion above.

Thoughts?

On the fly conversion is an option for both handhelds and burning.

You could also set up a new library (file/library/library manager) and import your ape files to it, then convert what you want as MP3 in batches.  

Set the option to delete the original OFF and do a few before you do very many.

How do I encode on the fly when burning?  I couldn't find any option to do that.

I'll look into playing around with a separate library for handling conversions.  Again, I think it will probably turn into a bit of a management headache, trying to remember which APEs I had converted to MP3s.  Is there any easy way to find this out, or perhaps automatically store a tag in the APE to indicate that it has been converted?

In the second library (call it MP3 library, for example) every file you convert can replace the file you started with.  So you can see which ones you've done.

Have you tried the help section in the program?

I ripped all my CD's to APE and am keeping these files as the 'masters'.  They are stored on DVD-R's.

I then converted the whole library to 190 KB MP3's for day to day use.  I created a custom field in the library to show which DVD-R each album was on.

My next task is to create files for use on my PDA and HD player from the APE files.  I am still trying to decide which format to use.  Again I will save these to DVD-R's and have a custom field in the library to know which disc they are on.

You could use a custom field to indicate which albums/tracks you have converted.

Hope this is of some help.

Jim,

Is there/can there be a way to convert on the fly for just simple playback, in addition to handhelds and burning?  I have everything stored as ape files on my work server, and I want to listen to the library at home (via VPN connection), but ape files are too big to 'stream' over the internet, so I don't get smooth playback.

If I could tell MC to convert on the fly to mp3, at maybe 192 or even 320 before 'streaming' to the house, I would be very happy.

I know on the fly conversion can be done for TiVo, but i don't know how to do it for my situation.  Any ideas?

Thanks
