Midas you are correct however I burned the same CD at 128 and 192 and could not hear any difference-I have a 2 CD drive player on my home system and could not tell which was which.

It all depends on the complexity of the music -- but if you want CD-like quality you should stick with an average bit rate of around 192Kbps (preferably VBR, i.e. Variable Bit Rate); 128Kbps is considered to be Radio Quality...

Nowadays you get a lot of MP3 files encoded to CBR 320Kbps, hence the need for something like this -- it makes more manageable files, without loss of sound quality.

Tried this app a while ago and while it works
well if you reduce the bitrate then when you
burn a CD it sounds like crapola-128 should
be the lowest setting for good listening.

@Kevin, webforf: fine by me. :)

Kevin: agreed. Midas: a large percentage of the software listed on this site has a donation button or reference of some kind. That's not the same as an advertisement or bundled adware.

MP3 Quality Modifier displays a very unobtrusive donation note / self-promotion only during the process which you can (and probably will) minimize anyway. It's in no way restricted in use or disabled in functionality because there is no "pro" version.
Please note that 3rd-party ads will never(!) be added in any of my applications. However, e.g. a donation note should be allowed in freeware, because your suggested term "adware" has a very low reputation and would make releasing new free versions impossible for me.
I hope you understand and accept the developers point of view... ;-)

Best regards,
Kevin S.

Not to look a given horse in the tooth (kudos for Kevin :), but shouldn't this be considered addware for the 'plugs' displayed while converting?

This is not stealth..

Leaves folder in AppData > Roaming

Folder named: "MP3 Quality Modifier".

Nevermind.. i missed the command line requirement.

UPDATE: here's a PAF launcher.. no more worrying about command lines.. | 1.02 MB
