I have just started playing with iTunes Match. I see some 300 tracks out of 1800 that will need an upload to the cloud, once Match has ended.

As the upload is very slow and uses the whole available bandwidth, I was wondering if there is a chance to mininize the number of tracks being uploaded.

I have read some messages of people suggesting to convert to AAC, then delete oroginal MP3, then launch again Match, blablabla.

 

Is there a well known working method on how to achieve this?

Hi,

If you add "cloud status" from view option in your iTunes library, this will show status as matched, purchased, uploaded, ineligible or waiting. Outstanding tracks will have status as "Waiting"

    Hi,

    There is no easy option. Converting tracks will not in itself allow songs to be matched. I don't think it matters what format you are trying to match.

     

    I have had some success, not a vast amount, when I have edited a track using Audacity. Firstly, I have checked that the track is in iTunes Store then checked timings. Often, the track in iTunes is one or two seconds shorter than the version on your computer. Edit song so that timings match - ps did not work where iTunes version was longer. Convert edited track to a different format.

    Is there a way to list unmatched tracks before iTunes will attempt to upload them?

    Could you clarify this?

    Hi,

    In iTunes select view from menu, then view options and then tick iCloud status from show columns.

     

    Once you have done this you will be able to identify the tracks awaiting to be matched.

    Yes, but what did you mean with "Outstanding tracks"?

  • Jimzgoldfinch Level 5 Level 5

    Tracks with awaiting status!

    Actually, converting a track that did not match from one format to another will almost certainly not result in a match. When you cross convert one lossy format (MP3) to another lossy format (AAC) you are actually throwing away more data in the track.

     

    The only success I have had in matching an uploaded track was when I re-ripped from the original CD at a higher bit-rate so there was more sound data in the track for the matching process to work with. I have never had success cross converting from AAC to MP3 or vise versa.

    Hi,

    I have had successful matches using this method especially where I have adjusted the timing - bit of hit or miss though. If the quality degrades from conversion to conversion, why is it possible to match 96kbs with 256kbs for example?

    It's probably just a quirk of the matching process that you got a match. If a track is cross converted from a 96Kbps .mp3 to a 256Kbps AAC there certainly isn't any data added in the cross conversion. I'm not saying don't ever try it; just don't expect to get a match just from cross converting.

    I have been looking at spectrograms of the same track encoded with MP3 & AAC. Quite different actually. That could be the reason?

    I could be. I don't know all the technical details but I do know that AAC is a more efficient encoder than just about any MP3 encoder so more data is kept when a CD is ripped as AAC than as MP3.

    Hi,

    I have not tried any rematching for a few months. However, I reviewed some tracks to see if could now get matches.

    I was able to match one track by Travis and seven tracks by Tracy Byrd. The Travis track has been in the iTunes Store for some time but the tracks by Tracy Byrd have recently been added as part of a compilation.

     

    I had to adjust timing on 3 of the tracks to match iTunes Store version. I then converted the format from AAC 256kbs to apple lossless. These tracks were successfully matched and downloaded.

     

    I tried this without success on around 20 other tracks.

    Ok, my first pass gave the following results: 1022 tracks matched, out of 1360

    The majority of unmatched tracks are lower bitrate ones, however many matched tracks had low bitrates too.

    Some unmatched tracks have the same duration/time.

    Mostly seems to be a waveform issue; pity because many albums are missing just one unmatched track.

    Just for the record, so roughly unmatched tracks in my library are 24% of the pot, however on the album side, the percentage of incomplete/unmatched grows to 50%.

    Not a big issue uploading 338 tracks, although being very slow
