Lavf55.33.100 AAC codec vs Nero AAC codec / 1.5.4.0

Hey All,
I cut out about 30 seconds of an audio from an M4a file using the latest versions of Audacity and FFmpeg. When I exported the file, the new M4a file came out with a Lavf55.33.100 codec. The original file was with a Nero AAC codec / 1.5.4.0. The Nero’s will play on my Mp3 player (Sansa). The Lavi codecs will not play on my Mp3 player.
How do I get Audacity to export the new file using a Nero AAC codec / 1.5.4.0?

Strange problem… As a work-around you can export to WAV and try another M4A encoder.

If I just need to convert a file without editing I’ve been using Kabuu Audio Converter. It can batch convert and once you’ve set-up your desired output location and desired output-format it’s just drag, drop, and click.

Or iTunes can convert to M4A.

Nice. Thanks.

Now I just need to figure out how to get Audacity to output the Nero codec (since I had to cut out a little of the original mp4) so my (quite a few years old) Sansa Fuze+ can play it.

I’m pretty sure Nero isn’t the only one that’s going to work…

Do you have the Nero CODEC? You can find it online if you search. Then, if you know the command line for the Nero CODEC, Exporting using an external encoder program. (I’ve never done this.)

Of course, another option is converting to MP3 but there will be some “theoretical” quality loss… and possibly some audible quality loss, especially if you use a low bitrate.

I agree. The device just didn’t like the version of the Lavf codec that Lame was spitting out. So after wasting time trying other creative solutions, I reinstalled Lame and it now uses another version of Lavf codec (even though I just installed Lame less than 2 months ago). I guess the version I recently installed was buggy so they quickly revised it. I guess that’s why they call it Lame. Anyway, now it’s working fine.

Glad it’s working, but LAME is not used for MP4/M4A. LAME is for MP3 and it’s been built-into Audacity for several years.

Oh… right… not Lame… I reinstalled FFmpeg. Was tired and cranky when I wrote the last post because of all the time waste. Haha.
