Is FhG AAC encoder bundled with Winamp 5.63 a decent one, or there are better free alternative?

But it's not fully supported (yet) as ACC is.BTW There no reason to go CBR with AAC it's a Lossy format. You're just wasting space and not gaining any audio quality.

Hehe, I expected to read that.But due to plenty of hard disk storage and maybe a bit of pareidolia (I want to believe it sounds better even if actually doesn't), I think I'll be sticking with CBR.But reconverting my CDs and FLAC to AAC is advisable, or am I probably wasting my time?I don't think I'll hear a noticeable difference between MP3 @ 320 kbps and AAC @ 448 kbps with the headphone I have (Sony MDR-V55), but maybe it's time to change and adopt a newer and more efficient compressing technology

Sorry for double posting, I'm sure I didn't click reply/quote twice.I forgot to mention I'll play these lossy files in my Samsung Galaxy smartphone (running Android 2.3.6), which doesn't support FLAC files, but I'll keep FLAC files ripped from CDs in HD for archival purpose.
To be honest, with low end/budget audio gear (no hi-fi headphone, regular desktop onboard audio chipset etc). I'm starting to wonder if there will be actually any transparecy difference between lossless and a well encoded lossy file by LAME or FhG, no matter if bitrate is variable or constant

I also see from your qaac command-line that your low-pass input to the AAC encoder is 24-bit. This might also increase the AAC bit-rate somewhat over inputting 16-bit.
Lastly, why are you using a low-pass at all? The encoder applies its own low-pass (VBR 4 e.g. has one at 16.5 kHz), and anyway, a very small percentage of the bit-rate is spent on (nearly) inaudible frequency regions.
Yeah, it's a Winamp exclusive from what I can see. But it's easy to make it work in Foobar: http://pastebin.com/TbCwDeSV
