Coding problem in Amadeus Lite ?

Hi, and thank you for reading.
AMADEUS LITE running on MacBook Pro OS Mojave 10.14.6

My question : When saving a piece of music under Apple « .m4a », it is well read in Itunes. But when played in my SONOS system (version XXX up to date) it returns an « incorrect coding » warning. This stays true with "Apple Lossless" Does somebody experience such a flaw ?

To be complete in my question, such problem did (and does) NOT OCCUR with Amadeus Pro 1.2 (former version), same system overall, that I happily preserved on my computer.

Thank you again for help. Andre.

Hi, please make sure that you are using the latest version (2.7.2). If you are, which precise settings are you using for your encoding? Have you tried playing with different settings? Regards,

Martin

Thank you. My version of Amadeus Lite is actually 2.7.2. I made a short test : MP3s are well recognized by Sonos (from AMD Lite), as I told before m4a from Amadeus Pro ancient version play well, but not m4a from Amadeus Lite 2.7.2.
In short, there seems to be a problem with AMD Lite. For the time being, because I use transcriptions in M4a, I must use my older version of Amadeus Pro 1.2 instead of Lite 2.7.2 that I bought because I thought it would be OK. Nothing very harmful, but it hurts a bit.

Hi, there are many possible settings for m4a files. It may well be that Sonos is compatible with some, but not some others. Have you tried using a variety of different settings?

Regards,

Martin

Hi again, well I made another short test comparing the outputs AMD LITE Vs AMD PRO 1.2, and the compatible output in SONOS with soft up-to-date.
You see the results hereafter :
[AAC = Audio Apple MPEG-4 (.m4a)]

LITE 2.7.2 AAC 160 KBTS NOT WORKING
PRO 1.2 AAC 160 KBTS WORKING
LITE 2.7.2 LOSSLESS 16BITS NOT WORKING
PRO 1.2 LOSSLESS (No various Bit Coding available) WORKING

I hope that it helps. Thank you for reading. Yours, AN

Strange, could you send me a link to one AAC that works on your Sonos system and one that doesn't? Best,

Martin

Hi, could you try the version now at

http://www.hairersoft.com/Downloads/AmadeusPro.zip ?

The files created by the previous version of Amadeus are perfectly valid but there may be a bug in Sonos's software which causes it to choke on files containing a 64-bit atom (these are required for file sizes above 4GB).

It now only creates a 64-bit atom when absolutely necessary. You may want to report this bug though: since Apple's own frameworks now create 64-bit atoms by default, you are likely to encounter these files more and more often. Regards,

Martin
