I just loaded a song into the T7 but it doesn’t show up when I access the Roon with my iPad, which is how I normally control the Nucleus. Just a little bit before I added a similar song and it did read that, though I deleted it because I wanted this newer version that somehow isn’t being read.
Nothing in Home > Recent Activity > Added? If the file tags are wrong, it might otherwise disappear somewhere where it’s hard to find, but it should show up there anyway
I did find the piece in Skipped files, where it says it was unable to import this file. I’m not clear why. It is an m4a file, which I thought was supported by Roon.
The posts seem to indicate that m4a is just sort of a holding designation and the underlying file data is what counts. Here, the track is in Apple Lossless, a format that has played for literally thousands of tracks on my Roon, including the very similar track I previously added just an hour or less before I added this one. My iPad’s power is almost gone and I’m getting a headache from this, so I will revisit tomorrow. Thanks to all who have responded.
Yes. And I think you will be able to get what you want into Roon.
A file with a .m4a extension can be thought of as a container - of audio-only files in MPEG-4 format.
They will have been encoded either with the Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC) codecs.
So all you will need is an app (dBpoweramp is excellent; there are many more - depending on whether you are running macOS or Windows) that can open, read and convert your .m4a object into one of the formats which Roon supports.
ALAC would be appropriate; and you can convert online without buying software at sites like this one.
Thanks for the advice Mark. I still don’t understand why such conversion is necessary, as I have literally thousands of other tracks with the m4a designation that work fine as Apple Lossless files (or Apple MPEG-4 audio, which I believe is the same thing, which is how this particular track is designated). I didn’t mention before, but this track is actually an audio track from an iMovie that was extracted using Toast. I have done this before, including a different track today just an hour or so before creating this track, and all the others work fine in Roon.
We wanted to ping this thread before it auto-closed. If you’re still encountering this issue, please respond to this post and upload a copy of the affected m4a iMovie-exported audio track here: Media Uploader
So as not to confuse things further, I trashed the audio file that could not be played in Roon. But before I did, I burned a CD with it, and then downloaded the CD into the Music app on my Mac Studio, and that gave me a Roon-usable audio file. I have no idea why I had to use this circular route to create the audio file–one would think that the audio file burned onto the CD was the same digital file that Roon originally rejected as “audio stream format not supported,” yet the presumably identical track, once it was on the CD, was readable in Roon. The un-readable file was called Audio 2025.m4a, while the readable file is called “2025NYAudio” in Roon ("2025NYAudio.m4a in the Music app). It’s the identical music. Both were Apple lossless files. Could it be that Roon just didn’t like spaces in the original title, even though the Music app played it fine?
No - spaces in the title are not a problem. It was likely to be the format of the audio stream inside the m4a container. You burned a CD and it appears as though the encoder used in that process then gave you an audio format recognised by Roon.
