You've done a good job Mulder. Nice, simple interface, and (but) with the option of the command line flag interface, which is imho highly appreciated by several people (e.g. to get rid of vbr flags in cbr files).
Maybe a possibility to make the interface maximized (some like that).
And about portability, only the Trolltech ....... is a registry key.
Otherwise chapeau!

V4.03 Build 774

Great program. Use it frequently for M4A conversions.

Regarding "stealth" status: Registry key "HKCU\Software\Trolltech" sounds like something related to Qt (the company that developed Qt before Digia bought Qt was called Trolltech). Though I cannot reproduce this locally. Key exists, probably because of the Qt installer. But if I delete (rename) said key and then just run the program, the key will not appear again! So how has this been determined?


webfork 2013-10-16 00:35

deathcubek: I saw this a bit too late but it looks like someone tested it and found the Trolltech keys. This hadn't been determined as this is a volunteer site and some people are more thorough about stealth testing than others.


deathcubek 2013-10-21 22:29

webfork, is there a specific testing procedure you are using/recommending here? I'd like to reproduce the result, but I fail. Maybe the person who did the "stealth" test just made a mistake. Or (s)he was testing an old version. Anyway, if nobody can reproduce the result nowadays, I'd advocate for changing the "stealth" status to "yes".

Confirmed that the app does not create registry keys under HKCU\Software\Trolltech.
Entry corrected.


Special 2013-11-16 23:11

It very much does make entries using the latest "LameXP-Portable.exe" method.


Theirs your keys.


Special 2013-11-16 23:21

Actually disregard my previous comment I might have been mistaken, also these comments need an edit button :/

@ Special: If you want to delete a comment you wrote, simply klick the little trashcan icon (below the version number).
You presently don't have/don't see this feature, because of your rank (R0).

@Special: Those registry keys under "HKEY_USERS/S-1-5-XXX..." store the user-specific configuration. There's one sub-key for each user in "HKEY_USERS". But you normally don't access those keys directly, because *your* key will always be mapped to "HKEY_CURRENT_USER" and that's what applications use to store user-specific settings. So, if at all, you should be getting a "HKEY_CURRENT_USER/Software/Trolltech" a key. But, as said before, I do not have such key here. Maybe, what you have found, was just a leftover from some ancient version.

I suggest you use ProcessMonitor from Microsoft/Sysinternals to see what registry keys LameXP really writes...

deathcubek: it sounds like you mostly got the testing thing ironed out, but just in case, there's a forum thread that covers a few different testing processes:

Is LameXP the only audio encoder that can convert opus files?


webfork 2016-05-20 02:07

I converted something to Opus yesterday with LameXP but TEncoder and TAudioConverter will also do the trick.
