So what i'm asking is which is better in quality: HE at around 160 or LC at around 280? What i'm looking for is the best trade off in quality and size. Two, tebasuna's recommended LC-AAC at a higher bitrate (-vbr 3 yields tracks in the range of 250~300 kbps) whilst you recommended HE-AAC at a lower bitrate (160 kbps). One, i need to reencode to AAC, so again keeping the original AC3 tracks is not an option. With LC-AAC you need simmilar bitrate as source and that lossy format change is not recommend and as Atak_Snajpera says there is no reason to reencode if source is not lossless. In this case you will get smaller size and keep maximum possible quality. If you bring about filesezie, only way to go is HE-AAC around 160kbps. I didn't want to get into these specifics because most people would then recommend different encoder and such. Indeed, i am using the Winamp Fraunhofer encoder, and indeed, my initial preference was using VBR 3 which yields an LC stream. Do i need to go higher? Can i go lower without losing perceptive quality? Should i consider lower CBR with HE profile?įor AC3 5.1 384 Kb/s is enough a low setting, I don't know your AAC encoder (maybe is Fraunhofer).įhgaacenc -vbr 3 (Fraunhofer-Winamp encoder) My initial preference is using VBR Q3/LC which gives me 5.1 audio files encoded at around 250 ~ 300 kbps. Giving all the above, and knowing that audio transparency and quality is usually subjective, what would be a good option? This application gives me the option of encoding in CBR AAC (bitrate ranging from 4 to 448 kbps in increments of 4, and profiles HE2/HE/LC are completely user selected) and VBR AAC (where i can choose a quality preset from 1 to 5, 5 being highest quality and largest filesize and where profile is strictly automatic, HE-AAC 2 kicks in when using Q1, HE-AAC when using Q2, and from Q3 to Q5, format profile is LC). I'm using a certain application (i'm not interested in suggestions of using another one or another encoder for that matter) that uses up-to-date AAC codecs. Now i've read in various posts online that AAC standards recommend around 260 kbps for 5.1 audio. Bytes are scarce, so my goal is to minimize bitrate while preserving audio transparency. Second, I have a large number of 5.1 AC3 audio file encoded at CBR 384 kbps that i want to transcode to AAC. I mean nowadays, waiting periods for buying guns are less than that in many states in the U.S :D !!

First of all, let me say that this is my first post here, and i really don't appreciate the 5 days waiting period between registration and posting :confused.
