Friend,

Been a long time since opening PowerTracks, but can offer an approach to consider.

Maybe just superstition, but I never trust a DAW for conversion to another format. I always render to a wav file, maybe a final stereo mix directly from the DAW, and rely on an external agent to manage the subtleties of format conversion. Thus render the PowerTracks session to a decent wave file. Then check out...

Would recommend buying the registered version. Shareware and freebie dismantles the mp3 codec in a month if you don't buy, but leaves all other native or free optional codecs fully functional.

Cheap option is to let the mp3 encoder to go south, keep the exquisite functions regarding other formats.

For mp3, need an open source supplement. Can go with this alone if only mp3 conversion is needed.

Go with WinLame front end for the LAME mp3 encoder:

http://winlame.sourceforge.net/

Then, get the actual mp3 encoder upgraded. Last version was something like 3.99.5. Receding into the past, but all you need or can hear any difference in.

http://lame.sourceforge.net/

Secret of the windows use of *.dll files is that the dll located in the program directory with the exe file of the program will use that dll over whatever is cluttered in the system directories.

You are looking for the lame_enc.dll file from the LAME page to put in the WinLame folder with the WinLame exe file.

From this point on, you are set. Will not fix world problems of hunger and injustice, but all issues regarding format conversion will be solved within the state of our current art.

Best,
John
