quick question for ac3 to aac

[10L23r]

which results in less loss of quality: using besweet to convert ac3 to aac, or using dgindex's built-in ac3 to wav decoder and then the nero aac cli? are the ac3 decoders significantly different?

I think the decoders are the same.
I supose you use BeLight, the last bsn.dll and NeroAacEnc to use BeSweet. Then the encoder is the same.
If there are one decoder free more updated maybe is ffmpeg (libav). Then I recommend you (with NeroAacEnc at same folder):

eac3to input.ac3 output.m4a -quality=0.35

well i know besweet has azid... but i recall that besweet uses floating-point, so maybe the quality would be slightly better

[tebasuna51]

Azid, NicAudio, ... all are based in the same free library with 32 bit float output. eac3to also send 32 bit float to NeroAacEnc.
