I have just started to burn my CDs to my harddrive as MP3s. For me sound quality is absolutely paramount. Not too bothered about file size. Having read the excellent postings on this website, I am using the alt preset extreme. Am I right in stating that when using this, it does not matter if the bitrate is set as 320? My concern is that I have read that CBR using the above preset is the best for audio quality but my bitrate is then set at 320. I do not want to burn over 800 CDs only to find the audio quality is not quite what it should be. Please also confirm that all I need to do is set the additional command line on EAC to alt preset extreme.

Thanks for your assistance.

Yes, you can set the encoder to "user specified", or something like that, and use the commandline:

--alt-preset extreme - %d

You can leave the bitrate at 320, as soon as you use a user specified encoder EAC does nothing with that setting.

There is a good article in the wiki that answers all your questions.

"--alt-preset extreme - %d" will not work - there is no piping with EAC, it uses a WAVE as source - therefore you need something like "--alt-preset extreme %s %d".

Ah yes, I forgot that. Sorry, I was confused with foobar.
