aac LC stream conversion with added meta data

[TommyTucker26]

Hello, I am trying to convert a large number of aac stream files to something that simply permits adding metadata.  I can do this by converting to FLAC or other lossless formats, but that grows the file size to much  larger as expected.  Is there a way in SSC to convert aac streams to a format that doesn't grow the file size significantly or lose quality by requiring re-encoding to a lossy format a second time?  If not in SSC, some other convenient way that just adds metadata, playable on most players without any processing of the audio itself, which I presume would have to remain in aac with a meta data capable container?

The program would allow you to convert the files, but also would change the size of the files.  Now if you need to add Metadata is better to use a different program like Stamp ID3 https://www.nch.com.au/tageditor/index.html

Thank you very much for your reply.  However, I looked at Stamp and I don't think it does what I'm looking for.  To add metadata It appears it can only edit an existing tag (aac formats have no metadata to edit), or re-compress the audio to a file format such as MP3 or Ogg which are compatible with metadata tags, but that would mean compressing an already compressed file, reducing its audio quality and/or growing the file size substantially.  I'm fairly confident there is software available that just adds tags in a suitable container without processing the audio again, such as the aac audio in an m4a container, but I haven't been able to find such software, unless SSC can do it.  That would indeed grow the file slightly as it would be adding the metadata, but that should be insignificant in comparison with the size of the existing aac files.  But possibly licensing issues mean such software is not available to consumers?
