Fraunhofer aac-lc

[djsoft]

If you need a specific codec, you can use it with Custom Codecs feature - but this is typically needed for special cases, e.g. to use an exotic format, or when a specific configuration of the regular encoder is needed (mostly the case for ultra low bitrates). You didn't say what's the problem with AAC in RadioBOSS is. Have you tried using it and faced any issues?

The codec in radioboss aac is a free codec.
The aac-lc is a near loss free codec.
Take a look at their site.
Or take a look at other playout systems why it said they deliver with their playout system.

The codec in radioboss aac is a free codec.

RadioBOSS doesn't use FAAC. If your installation uses FAAC it means you have a very old RadioBOSS version that needs to be updated. When you select AAC in RadioBOSS it effectively encodes in AAC-LC, and for AAC+ it's AAC-HE (the actual options depend on bitrate).

Ok I'm using version 6.0.1.8

 

[Kevin H]

I have it now at 192 kbps aac.

Is this aac-lc ?

If you selected the AAC option (not AAC+) then it's AAC-LC.

the FDK AAC codec is build in ffmpeg included with RadioCaster

cd c:\program files (x86)\radiocaster\plugins
ffmpeg -hide_banner -h encoder=libfdk_aac

But I use fdkaac.exe because I'm used to the command line of this codec, FFmpeg simply has a different syntax and I haven't learned it.

C:\Program Files (x86)\RadioCaster\Plugins\fdkaac.exe - -R -I -p 2 --raw-rate 48000 -f 2 -w 22050 -b 320 -o -

this is parameters for 48K, works fine.

RadioCaster allows using variables in the command line, so this can be made more universal, e.g.

C:\Program Files (x86)\RadioCaster\Plugins\fdkaac.exe - -R -I -p 2 --raw-rate {SampleRate} -f 2 -w 22050 -b {Bitrate} -o -

So, if I enter these variables, I'll be able to select them from the drop-down lists when adding a new sample rate encoder, and it will update without increasing or decreasing the pitch of the sound?

Basically this will substitute {SampleRate} with the actual sample rate as selected in the encoders section. Same for {Bitrate}. The rest depends on what the encoder will do.
