OK, just some basics then. You can spend days or even weeks on the Net learning about the finer details of audio compression. But this is not the Hydrogenaudio Forums, nor am I an expert in the matter.
Ok there are alot of settings in lame in cdex so i want to get it right.
There is no universal “right” here, so don’t worry about it. Do what you’re comfortable with (and only your own learning process and experience will tell you this).
Im using cdex 1.70 beta 2 and lame 3.97
You’re up-to-date there.
anyway the settings:
CDex comes pre-configured, except for updating to your preferred Lame version and entering an e-mail address for the remote CDDB. No need to change anything really, unless you have a good reason to.
firstly thread priority?
Refers to multitasking on your PC.
anyway mpeg version, i guess ill just use I
Correct, don’t change it.
Mode: stero, joint stero, forced stero, and mono. What are the differneces between these steroes?
For best results use Joint-Stereo.
then 4 checkboxes: Private, checkdum, original, copyright?
then quality: alot of options i dont understand…
Read up on these Lame settings if you must. Presets are provided for your convenience and “preset fast standard” is recommended. If you need smaller files, look in the guide I linked to for alternate settings.
then on the fly mp3 encoding
On-the-fly means encode while you rip (as opposed to first rip, then encode).
and finally vbr method and vbr quality (only available in some quality settings)
There’s CBR (Constant Bit Rate), VBR (Variable Bit Rate) and ABR (Average Bit Rate) to choose from. Google if you need more details, an often used and simple setting for everyday use is CBR@192kbps.
On some cds media player knows the artist album, song names, etc, how?
Audio CD’s can have something called CD-Text or your media player can look them up in an online database. Mp3’s have ID3-Tags.
If you rip an mp3 with lame on the same settings twice, will they both have the exact amount of bytes?
I would think so. Why don’t you try it?
when lame comes to a new version, that is reccomended, should i re-rip my mp3s with it?
If you (think you) can hear the difference and you have the time, feel free to. Always rip from the original CD or WAV file, do not re-encode existing mp3’s.
Also, if you copy a CD and rip the copy to mp3, will the files be exactly the same? If so what are blank discs for audio for?
Another experiment you can make (but you certainly won’t hear any difference). Blank CD’s for Audio are intended for use in standalone recorders that don’t support normal CD-R/RW discs.
and finally, if you convert your audio cd to waves, are the songs exact lossless copies?
thanks to anyone who answers - sorry for so many questions
You’re welcome - I hope it can help you get started.
