I don't get some of your answers I only asked for an audio editor that can export LAME3.98 -m j -V 4 -q 3 -lowpass 20.5I don't get some answers like Also, don't mess with LAME's defaults unless you have very specific reasons to do so. Use just -V4, leave out all the rest. What do you mean by that? and how you do that?
To more directly answer your question, Audacity can do what you want. You need to download the LAME .dll separately, but it will tell you that and give you a link when you try to export as .mp3. However, as other people have said, using a full fledged audio editor to encode to .mp3 is a bit needless. If you have your .wav or .flac files, you can use a program like lamedropxpd to easily and quickly encode them. Foobar2000 is also very popular, but it has countless functions beyond being merely a frontend for encoding.
I tried with audacity it says to download the latest lame encoder v3.99.3.

I tried with audacity it says to download the latest lame encoder v3.99.3. I want to know how you can use LAME3.98 -m j -V 4 -q 3 -lowpass 20.5 with audacity now.
As detmek explained, he is using the output of MediaInfo to determine how he should be encoding files. The file he analysed was likely CBR 320, which is why the lowpass shows as 20.5. MediaInfo incorrectly reports the settings used for CBR files and erroneously states that they were encoded using V 4, because MediaInfo for some reason requires that a V level be shown in its output. In order for MediaInfo to show something other than V 4, the file must be VBR, in which case it will display an accurate V level.It is nonsensical to decide upon encoding settings (and LAME version) from such a methodology, but it does explain his unusual request.
