w that less re-encoding is done:
Before: ffmpeg -i sample.flac -c aac -b:a 200k -bt:a 0 -y before.aac
size=2776KiB time=00:03:10.98 bitrate= 119.1kbits/s speed=14.4x
After: ffmpeg -i sample.flac -c aac -b:a 200k -bt:a 0 -y after.aac
size=3897KiB time=00:03:10.98 bitrate= 167.1kbits/s speed=2
with AAC encoding to know how to
fix the above, that'd need some more work / additional hints.
