I am pleased to announce the launch of FREE Reference Quality MPEG-4 Audio solution from Nero, in the command line form!

* First in the world FREE 2-Pass MPEG-4 AAC Encoder
* Support for mono, stereo and multichannel encodings
* Support for sampling rates up to 96 kHz, up to 32-bit Floating-Point PCM input
* Compression Ratios ranging from ultra high (58 CDs fit on one!) to High-End Audio (2.5:1), for absolutely perfect audiophile encodings
* Support for Embedded Album Art (Covers, Booklets, Lyrics!)
* Store Entire Audio Album in a Single .mp4 File with all the Features of an Audio CD embedded inside, but at a fraction of the space!
* Reference Quality MPEG-4 Audio Codec

You can use fractional values.

BTW. Using 2-pass with VBR makes no sense smile.gif VBR will just use how many bits it needs.

Hmmm using single pass created an audio file of 132kbps while a 2pass was 127kbps. Both sound the same to me ... just curious ...


I was experimenting with 2-pass vs single pass, and I noticed similar results. I had quality set to 0.6, and encoded Thursday's "A City by the Light Divided." Single pass came out around 74.4MB, with a bitrate ~224, whereas 2-pass came to 70.7MB with a bitrate of ~215. Interestingly enough, that's exactly the bitrate I was looking for. Almost every other album I've done w/2-pass averages ~215kbps.

yeah w/2pass the bitrate comes out more of what i wanted. But Garf said that we shoudlnt do 2pass vbr so i guess i gotta go lower w/the q values.

It also takes way too much time to encode w/2-pass. If there's really no point in using it, then I figure I'm not going to waste my time. I did the same and lowered my q values.

Although, I believe the reason it takes so long is that I have all my music archived on DVD+R's, and foobar2k seems to like to convert 2 files at a time, which slows the whole process down quite a bit when it comes to transcoding directly from a DVD+R.

i dont think its hte media source. it takes quite a bit w/hdd sources using 2pass. but then again it is going @ it twice ...

Well, unless I'm mistaken, data is burned onto a disc in linear fashion, and is read in linear fashion. Having two separate files being read causes the laser to jump around repeatedly, trying to multitask, which slows the spin-rate of the drive down significantly. (Off topic, sorry gang)
