Audio conversion FLAC to MP3.

[Bulbbegins]

I was wondering whether any of my learned friends would be able to help me out with an audio conversion problem.
Recently, I was given a drive containing audio files encoded in FLAC format at 24 bit/96khz, while I can listen to these on my PC without issue, I'd love to shoot them around my house and listen on my assorted Sonos units, but Sonos only supports 24 bit/48khz maximum.
Any idea how to downconvert; MP3/320kbps is fine. I have dropped the files into my DAW but while I can batch convert/output/save to MP3, the maximum bitrate I can save to is 128kbps, despite forcing the DAW to encode at a CBR of 320kbps. Curiously, I can save the FLAC to a WAV, but the files are unplayable on the Sonos system (despite other WAVs playing fine).
Anyone got any ideas?

I don't know what you mean.

Here I immediately advise you to find a good converter that can convert FLAC to MP3. Not all converters can do this efficiently, and after conversion, some of the files that were made from FLAC to MP3 simply die. Therefore, before you make FLAC to MP3, you need to make compress. Best of all, if you don't know how to do it, I advise you to watch the tutorial on this site -- movavi.com. And by the way, there is also a cool not only audio converter that does not damage the file but also a video converter.
