What software can convert to AAC+ (HE-AAC v2) audio format?

Question

Audio

Good afternoon, tell me please, I just can’t find a converter that can convert an audio file from MP3 or another audio format to AAC + format (namely Plus at the end, i.e. the second version of AAC, the one that is now the most optimal in radio broadcasting, there is less space for all occupies while maintaining decent quality)

Answer 1

Must fit Nero AAC Codec with key-hev2

Advanced features / troubleshooting:
-lc           : Forces use of LC AAC profile (HE features disabled).
-he           : Forces use of HE AAC profile (HEv2 features disabled).
-hev2         : Forces use of HEv2 AAC profile
                Note that the above switches (-lc, -he, -hev2) should not be
                used; optimal AAC profile is automatically determined from
                quality/bitrate settings when no override is specified.

MeGUI knows how to work with it , so as not to decode it with your hands.
Well, or you can write a script so that lame.exe decodes to stdout, and neroAacEnc.exe takes a stream from stdin.

Answer 2

ffmpeg -i input.wav -c:a libfdk_aac -profile:a aac_he_v2 -b:a 32k output.m4a

The bitrate settings are just an example.
