VCD Audio -> mp3/aac
If i was to strip a vcd of its audio & encode it to either mp3 or aac for playback on my ipod, what would be the opitmal bitrate or encoding settings i guess.

I believe vcd audio is not cd quality and thus maybe mp3 -aps would be over kill ... as would faac q-150.

Just want some opinions so i dont have to transcode mulitple times.

thanks

VCD audio is MP2 @ 224kbps. I wouldn't bother transcoding to MP3 at any higher than 160kbps.

hmm so CBR would work? if you say about 160 ... then -alt preset medium or -q125 might work then correct?

thanks!

Try --alt-preset standard. I'm pretty confident that it will use a bitrate under 200.

At least a lot of software MP3 decoders can decode MP2 as well, maybe its worth a try to see if the ipod can play the MP2 file directly?

would i need to reencode the 48Khz to 44.1KHz?

vcd audio is 48 i believe ...

vcd audio is 44.1khz. By my experience, encoding vcd audio track into MP3 at 128kbps is more than enough.

yeah ... nm
vcd audio is mpeg2 @ 224 44.1Khz

ill just do q-100 aac for my purposes (ipod listening)

Thanks!
