I am getting ready to transcode my ~2TB flac library to AAC-LC in an MP4 container and want to be sure I get it right.

My intention is to encode at ~96kbps TVBR with QAAC. The goal is for portability and streaming, and this seems to be a good quality level that will give reasonable listening (I still have the lossless archive).

Is TVBR widely supported? I know many years ago when I used to encode to LAME MP3 VBR ipods had a hard time with it.



I need to pick the right tool for transcoding and have some specific tasks that I want to achieve and can hopefully achieve all of them in one transcode step.

- Scale down album art automatically. Probably to <50kb and 500x500. Is this still to big?
--- 90+% of my albums have embedded and folder.jpg, a minority have one or the other. If they differ, I would like to scale down from the higher resolution one.

- Identify HDCD tracks, and encode to 24b on the fly

- Identify pre-emph files and de-emph

- Apply EBU R128 ReplayGain ( I still need to calculate EBU R128 ReplayGain values for my flac files)

Is there a tool that can do all of these?

I am questioning your goals here. If using ~96 kbps is your goal I assume you are looking to save space. If so, why the embedded album art, its a complete waste of space. Only windows media player/zune dont read folder.jpg. All other players like winamp and foobar do, as well as android and rockbox. (actually im not sure about itunes/ipod).

relying on folder.jpg requires you maintain the same folder structure, which may not be the case. Embedding is to make sure the art is there. I can probably scale down the size to 25kb max. However, I'm not sure that I can rely on having album art across multiple players if its not embedded. Am I wrong?
