Could Not Open Mp3 Encoding Library

[Gale Andrews]

It could be that this is the problem:

Code: Select all

Error: Execution of command 'lame-"C:UsersWorkshopDesktopAmerica.mp3" ' failed (error 2: the system cannot find the file specified.)

Perhaps writing an MP3 is trying to call some other MP3 encoder you have installed somewhere else.

This looks as if it may then be preventing the LAME for Audacity lame_enc.dll initialising correctly.

I'm not sure how seeing as this is a new PC i built only a few days ago and this problem happened straight away.

*rubs chin* Could it be a permissions thing? Windows 7 can be shit that way sometimes. Perhaps uninstalling it and reinstalling it to say my D drive (HDD) might fix it?

Can you export as WAV (or as MP3 at the Audacity command-line) to "C:UsersWorkshopDesktop" ?


Gale

[Damienb]

Yes I can.

I recorded a bit, then exported as Wav, tried to export as Mp3 (it failed), it worked exporting to external program with file extension *.mp3

Here's the log.

Hey,

As this is still doing it and I'm using the external program option now, how can I tell the lame.exe to export at 160kbps? Normally with mp3 selected you can go to Options and change preferences, but clicking options with (external program) selected doesn't give me that ability to change the output.

Any suggestions?

Damien

When using "external program" export, you can add any command-line options to the export command.

There is a full list of command-line options for LAME here: http://lame.cvs.sourceforge.net/viewvc/ ... itchs.html
You will see that the switch for bit-rate is "-b" for constant bit rates.

So for 160 kbps CBR (Constant Bit Rate) you would use the following command:

Code: Select all

lame -b 160 - "%f"

For a similar bit rate, but higher quality VBR file, you could try:

Code: Select all

lame --preset standard - "%f"

Hi Damien

Thanks for answering some questions on the Forum, much appreciated.

If you search for lame_ enc.dll on your whole computer including hidden and system files, how many copies of it do you have?

Have you tried the following, if not can you do so? Quit Audacity, copy lame_enc.dll from where it is installed, then paste lame_enc.dll into the folder where you have Audacity installed. Then uninstall Lame for Audacity and reboot. Then edit audacity.cfg so that it has only the following content:

Code: Select all

NewPrefsInitialized=1

Finally, launch Audacity. It should just export Audacity in that case.

If not, you could download Dependency Walker, launch it, drag lame_enc.dll into it, then File > Save the .dwi file and e-mail it to me at our feedback address .

Thanks Steve,

And Gale, I'll get onto it just after I mix down another podcast I look after.

Okay tick this as solved Audacity followers.

I uninstalled everything, I deleted every reference to Audacity and to LAME (including original downloaded exe). Restarted PC.

I re downloaded Audacity.
I installed it on another drive that wasn't windows. In my case F drive.

I re-downloaded LAME as per the help wiki and installed that on the F drive also.

Did a test record and export. Works fine.

I wonder if this is to do with a permissions/windows directory HDD freaking out about a program trying to access a .dll

*rubs chin* I hope this thread serves as a more updated info sink about this error as older versions had threads about it in the past.
