Hi there, I have a lot of audiobooks imported into itunes. They are aac-files mono 32kHz 28kbps and sound just fine, maybe because i used itunes "optimize for speech"-feature. Now when I try to build an audiobook from those files using the same settings, pass-through doesn't seem to work: my CPU hogs to 100% for quite a while, obviously reencoding the complete audio, and the resulting audiobook sounds considerably worse the the individual input files. So what do I have to do to use iTunes to encode the audio and ABB to just join the files? Thanx! p.s. I did search the forum but found nothing, please forgive me if I have not looked deep enough - hints and links are as much appreciated as the solution itself... |

It seems that audio encoded with "optimize for voice" or VBR is too different to work with pass-through, thanks to Splasm Support for pointing that out to me, now I know what the problem was... |

I've noticed some improvements in sound quality with the "optimize for voice" option turned on. (Like others, I've been importing into iTunes first to take advantage of the CD error correction.) I would hate to lose the improvements. Is it possible that at some point ABB would support this? |

Probably not, if we were to use Apple's method on say, files coming in from CD. The end result would be the same - files with audio formats too dissimilar to permit joining into a single audio track. I think we could work around it up to a point, and take it to an extreme by ripping to uncompressed files first, then compressing all at once in a single pass, but that would cost additional build time and a lot of temporary disk space. |
