Koz’s guitar track has no metadata (Artist, Genre and so on). Perhaps your files have metadata.
Any AIFF saved by iTunes will have Normalisation (NORM) and Gapless (PGAP) information added to the file.
If Audacity exports an iTunes-created AIFF file containing NORM and PGAP data, it duplicates the Normalisation information towards the top of the file (but removing the “NORM” designation from both instances) and removes the Gapless (PGAP) information entirely. This could be quite sufficient to upset iPod running on battery.
I have a similar issue.
Seems like the metadata is at the heart of it.
Aiff with metadata, not in track order and does not play properly.
WAV without metadata works fine.
Aiff works with iTunes and on iPad .
Am pretty sure I have/had an Amedeus aiff on my iPod worked fine
but,again no metadata. So maybe not apples to apples.
That is, if you save a single AIFF created in Audacity in Amadeus and Peak, do they empty the metadata? But they don’t do that with AIFF’s created by iTunes?
Have you tried iPod connected to the computer, to rule out battery power as the reason it will not play Audacity-created AIFF’s that contain metadata?
Please generate a tone or record something in Audacity then give us steps 1, 2, 3 to reproduce this
problem. Don’t use AIFF files already created by iTunes because we know Audacity modifies iTunes NORM and PGAP.
Tell us exactly how you are splitting the tracks using Export Multiple and exactly what you are typing into Metadata Editor. Tell us exactly in what way the exported files are “not in track order”.
Better still, please upload some AIFF files produced by Audacity Export Multiple from a tone or a recording to a web server so that someone who has iPod on Mac can try them.
Are you talking about AIFF files written by iTunes, including those converted by iTunes from WAV or AIFF files produced by Audacity?
If so, isn’t that a useful workaround to the problem?
cassette tape to mac os x 10.5.9
nearly always record side 2 first, so have to cut and paste to get sides in order
normalize to max minus 1 down click (12.0 to 11.7)
use point labels
multi export with point labels
export aiff 16 bit 44100
add to itunes library
itunes can play but songs out of order (see attachment)
ipad can play over icloud out of order
ipod classic does not play or plays first and then skips around without playing.
Not all code handles problems the same
I think Peak which finds the 2nd file on as bad no end of file
and ipod software have limited ability to handle a file that is not 100.00%.
comments on tiff
top album file splits reopened and resaved with Audacity, out of order but play in itunes
second album (unknown) file splits opened with Amadeus and saved, in order, plays in itunes, metadata gone
third album file splits from Audacity out of order, plays in itunes, skips in ipod, modified metadata in itunes added track number to name to see if helped
fourth album file split into WAV files, in order, plays in itunes, plays in ipod,no metadata itunes.tiff (119 KB)
First, none of these files come back out of iTunes .
I opened the Audacity file from the split in Audacity as an aiff file,
Then I saved a copy of the file as aiff.
I opened the Audacity file from the split in Amadeus as an aiff file,
Then I saved a copy of the file as aiff.
Lost metadata, but in order and played.
First the good news.
The files seem to play everywhere else just fine:
iTunes on my computer
iPad from iCloud ( maybe an apple copy, but one tape working on would have no copy)
Apple tv from iCloud .
The exports as WAV files work on iPod.
Now the word from Peak LE
I opened the Audacity file from the split with Peak,
The first file opens and a copy is saved.
None of the other files open
can’t find end of file.
Now the BAD news
Multi export song name, artist put in metadata editor no work
Multi export with song name as label, all same artist no work
Multi export with default letter for song name no work
The files when synced to my iPod
do not play.
It might play first song but then it displays the title to the 4th,6th, 2nd and back to the first
without playing a note.
The file is not right.
iTunes looks at it, gets an error and says I will fix that for you.
Amadeus does the same.
Peak says whoa wait a second, let me tell this guy the file has a problem.
iPod software does not catch error, has no code to handle the situation
and flies off in search of the end of the file.
Try to get the album to play a couple of times
and you have to restart the iPod
to get it to work with any song?
It’s so confused.
You kindly offered to test AIFF’s with no metadata. Are these tests with no metadata? If so, what does “no help” mean? Were the files out of order in iTunes? Did the files refuse to play in iPod when running on battery?
I think you have already said that if metadata is added in Audacity the songs may be out of order in iTunes. I’ll see if I can reproduce the “out of order” problem in iTunes, but if not, your steps above are not accurate enough for a bug report.
Is this with the cable still connected to the iPod, or with the cable disconnected, so that the iPod is on battery?
Let me amplify
Turn that dial all the way up to 11.
In the first test,
I open with Audacity,
It recognizes a file with some issues
but it handles those issues so I can work with it in Audacity.
However, when I write out a copy
it does not write out a fixed aiff file.
In the second test,
I open with Amadeus,
Behaves like Audacity.
However, it writes out a corrected aiff file.
I just rechecked to see
and yes the Amadeus files work correctly in iPod.
One other wrinkle.
Peak finds fault with the Audacity resaved copies of the split files
Peak has no issue with the Amadeus resaved copies.
It would be most helpful if you avoided writing in abbreviations.
“just a letter”: What does that mean in English?
“and a number”: Likewise, what does that mean?
“no title, no artist”: If you are referring to metadata, please say so.
“no work”: We’ve had this phrase before, but I’m still not clear about the details. Assuming that you mean the same “no work” as in this post, you go on to say “iTunes looks at it, gets an error and says I will fix that for you.” I doubt that iTunes actually said that. What was the actual error /warning from iTunes?
Precisely what issues?
Not until there is a clear description of the fault.
In what way do AIFF files produced by Audacity fail to meet the AIFF file format specification? If the files do not meet the file format specification, then that is a bug that can be addressed by the Audacity developers. If the files do meet the AIFF file format specification, then it is not an Audacity bug.
Not in Safari, or Firefox either
but I did get to File Save As in Firefox
I do not have an iPod. Koz or someone else who has an iPod could try. The clearer the problem is, the more likely someone will try.
Miller aiff did not play on my ipod
split Miller aiff did not play on my ipod ( 4 10 seconds splits)
Buffy aiff already on my ipod plays just fine
I readded the bluegrass tape aiff on my ipod and it plays just fine buffy.tiff (264 KB)
How do we interpret the result that this file does not play on your iPod, yet Koz tested that same file on two different iPods and it played on both with no problem?
Could it be that the issue depends on a specific iPod version, or perhaps a specific version of iPod firmware, or something to do with the version of iTunes that is used to load the AIFF files onto the iPod?
From a quick Google search it appears that there is a common problem with Mac OS X getting AIFF and AIFC files mixed up.
These types of issues with AIFF files come up on forums for other software that are unrelated to Audacity, including Sound Forge, Logic, ProTools and Ableton Live.
The best “solution” that I’ve seen in these forums is to not use WAV rather than AIFF.
Do we have any direct evidence that Audacity is writing AIFF files that are not compliant to the file specification?
