Lightweight audio encoder, with support for a large number of audio formats and a neat interface. I have been able to optimize hundreds of audio files with a good output quality and without having bugs or complications in the renaming of output file names that other encoders have in the batch convertion of multiple folders.

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

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

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:

@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...

@ 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).

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

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


Theirs your keys.

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

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".
