Audacity Forum

Hi

I have just insatlled Audacity V 1.3.13 (Beta). In addition i have loaded Lame 3.98.3. Using W Vista.

I have imported an audio clip in AIFF format made some changes and want to export into MP3 format.

for most times i try the result is an unrecognised file; however every now and then its works. To get 3 x MP3 clips so far i have had to attempt it about 60 odd times.

Any ideas?

Thanks Lee

What application reports the MP3 as "unrecognised"? What happens if you import it back into Audacity?

Have you read this page and what are your MP3 export options?
http://manual.audacityteam.org/man/File_Export_Dialog

What project rate are you exporting at (bottom left of the Audacity window)? Are you using File > Export or File > Export Multiple? With Export Multiple you must make sure the track is unmuted, because Audacity does not export muted tracks but Export Multiple does not warn you of this.

Let's split the process up.

Change the Audacity Preferences to 44100, 16-bit, Stereo. Not 32-floating, not Mono. Restart Audacity.

Download this brief music file.

Import it into Audacity and export an MP3. Only do it once. If it fails, write down exactly what happened and report back.

Thanks for responses; will post all the information later

Cheers

Thanks Gale

FIrstly, yes i have read the above link and i appear to be doing nothing incorrect; surely if its worked a few times and all i am doing repeating the same process then i am on the right path.

The project rate in the bottom left of Audacity is 44100.

I am using File > Export and the track is unmuted.

With regard to the unrecognised file; One i have exported using the above method; i look at the file from outside Audacity; hovering over the exported file shows the following "Type: 11File" whereas hovering over the 3 that have worked reads "Type: MP3 Format Sound"

Thanks Lee

Gale & Kos

Thanks for the info but i think while dealing with the things KOS asked me to do i have found out the problem; i has since tried it a lot with varying WAV or AIFF files and its worked every time.

It was the file names i was using; i had - & . in them and it seemed to cause the problem.

If it starts again; i'll re activiate the post.

Cheers again

There is no reason you can't use "-" and "&" in a file name (though it might create problems if you send the file to someone else or use it on the internet). But the dot (.) is treated as a delimiting character for the extension of the file (the characters that state its format, like ".MP3").

So everything after the first dot will be regarded as the extension if you just type a file name with dots in Audacity, ignore Audacity's warning that the exported file may not be playable and save the file.

For example, If you type "song.11" and export it with that name, Windows sees that as an "11" file. You can play the file if you select it in Explorer, right-click, choose "Rename", hit END on your keyboard, then type ".mp3" (without quotes) and save the rename. You may see a warning, which you can ignore and just save the change.

The better solution would be to type the file name in Audacity as "song.11.mp3" (again without quotes) so that you add the .mp3 extension. Then the file will be saved correctly and Audacity will not warn you about it.
