I'm in the process of encoding a bunch of CDs into OGG for streaming. I want to stream at an average 128kbps, so I'm using -q 4.00 with the aoTuV beta 2 encoder. Overall, the average bitrate of the files is very close to 128kbps. However, I have a few questions:
1. Because the -q setting is for "Quality" and not bitrate, I'm worried that I will run into files that will end up at a really high bitrate (i.e. 200kbps). 2. I'm also worried about cases where perhaps there's silence in the first half of the file (e.g. hidden track) and b/c of this the actual musical part gets an extremely high bitrate. Can anyone who has encoded lots of material comment on these issues? Should I be using the ABR/CBR mode instead? Thanks, -elan |

I think ABR might be a better option if you are worried about the bitrate jumping about too much, though from my experience, aoTuV's bitrates are quite stable.

CBR better than ABR? Are you sure that's what you ment?
I'd suggest trying the managed bitrate mode of the latest 1.1RC. -------------------- "To understand me, you'll have to swallow a world." Or maybe your words.

I'm going out on a limb here, but can't you just do a VBR with a max of 128kbps?

If the q setting is low, the average bitrate will be well below 128kbps. If it is high, the bitrate will be an almost constant 128kbps. At any rate, putting such a low max defeats the purpose of VBR, because harder to encode portitions which require a higher bitrate are limited to only 128kbps, which is hardly enough for transparency in lots of cases.

That would be the case if you'd use ABR. When using quality mode, the track just gets overall bitrate smaller than 128 kbps and the musical part at the end of the file becomes out as something near 128 kbps. |

QUOTE 2. I'm also worried about cases where perhaps there's silence in the first half of the file (e.g. hidden track) and b/c of this the actual musical part gets an extremely high bitrate. Just use an audio editor (e.g., Audacity) to remove the silence. [EDIT] proper quote tags.
