I agree with manolito here. I also convert all audio in my encodings to AAC, originally I was using eac3to+NeroAACEnc but switched to eac3to+qaac about 2 years ago.
This is my typical command for stereo audio in TV shows:

Code:

set eac3to="%PROGRAMFILES(X86)%\AVTools\eac3to\eac3to.exe"
set qaac="%PROGRAMFILES(X86)%\AVTools\qaac\qaac.exe"

for %%a in (*.mkv) do (
	%eac3to% "%%a" 2: stdout.wav -downStereo -normalize -log="%%~na_dec.log" | %qaac% --abr 80 --quality 2 -o "%%~na.m4a" --log "%%~na_enc.log" -
)

Filesize savings are quite nice, especially when you strip off multichannel AC3 384kbps -> AAC 80kbps for entire series (10 seasons * 24 episodes) without noticeable audio quality loss.
