Last thing I'd like to understand is why iTunes erases new comment fields scripts after updating. So it's not true iPods need the comment field to be filled, they simply need iTunes to receive and incorporate the last change before sync (and the comment field is just a trick to do it). Now I understand why iVolume marks the comment fields, and why if comment disappears the volume change in the song info doesn't. Thank you very much Jim you've been very useful to me.

If i understand this correctly, the removal of comments will update file BUT as you have not changed anything, the sound level will not change. The removal of a comment will trigger a "difference" between the songs in your library and your iPod/iPhone, and those songs will then be updated." If you've already performed adjustments on your iPod or iPhone, and you want your device to be reset to the default Sound Check volume adjustments, then select both of these options and synchronize your device. When selecting Forget Analyzing Results, the volume adjustments are reset in iVolume. If you have already synchronized your devices, then they have already been updated. When choosing Remove iVolume Comments, a dialog box is displayed that says "Please note that the volume adjustments may not be synchronized automatically to the iPod if you remove the iVolume comments from the selected tracks". This option will remove iVolume comments from your library. You can also choose to "Forget Analyzing Results" or "Remove iVolume Comments". iVolume uses the date and time in the comment, so that if there are any subsequent changes made in iVolume, it will trigger another update. iVolume only writes the comment if there is a volume adjustment made. Basically, iVolume "tricks" iTunes into detecting a change to a track by adding a comment to the song. " Once iVolume makes volume adjustments to your library, it also updates the comment data for the adjusted songs to ensure that these songs get updated on attached devices (such as an iPod or iPhone). I now understand why Ivolume makes reference to comments. IVolume doesn't seem to be effective in increasing low levels above Soundcheck, since results are the same (none of the low tracks had +17,20 dB gain, while high ones had -3,2 dB gain as expected). Soundcheck appears to be more effective than iVolume in reducing high levels, so maximum output is lower but differences between high and low files are less perceptible. Listening tests on iPad and iPod (after reset and re-sync) were positive again, resulting in good normalizing effect for all the songs (comparing to the great volume gaps I had made).īoth Soundcheck alone and iVolume (with soundcheck on) appear to be active on volumes, both by reducing the high levels and increasing the low ones, in iTunes, IOS and iPods devices. The Matched AAC of Song 1 got 94,75 dB after iVolume

So iVolume made these adjustments: -3,2 dB to the Full versions and + 17,2 dB to the Low versions.Īfter iVolume adjustments, I repeated the test and got these results: In both devices Sound Check resulted to be very effective on normalizing levels, to my ears.įinally, I started iVolume scan of the tracks in iTunes (which I had collected into a "Full" album and a "Low" album). So I also downloaded the AAC file and played it the same way, analyzed, and obtained 91,63 dB (*obviously the same for both the full and low versions).īefore adding iVolume I listened to the tracks in iTunes Match on a iPad Mini and on a iPod classic (after sync). These were the results with only Sound Check:

So I sent back the Mac output to Logic Pro (by SoundFlower), and I recorded the output into new tracks while playing each song, then bounced into a new mp3 file for each, and analyzed. But I wanted to have a measure of the results. They sounded very similar, and I hardly noticed a difference between Full and Low versions. Then I've added the six files to iTunes Match, let it update, and then played them with Sound Check option on. I analized the six mp3 files with MP3 Gain Express and took note of the levels. I imported each song into Logic Pro, and made two different mp3 files for each song, one at normal (full) volume, the other at a very low volume (main output at -20dB at bounce). I've made a little test with iTunes Match and iVolume.įirst I have chosen three songs, not yet added to my library.
