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 do not think you can easily de-emph with dBpoweramp and SOX together.
