I need to convert audio files to mp3 using ffmpeg.
When I write the command as ffmpeg -i audio.ogg -acodec mp3 newfile.mp3
, I get the error:

I also ran this command:
ffmpeg -formats | grep mp3
and got this in response:

I guess that the mp3 codec isn't installed. Am I on the right track here?
High quality for Mac OS works perfectly!
ffmpeg -i input.wma -q:a 0 output.mp3
Try FFmpeg Static Build Link
Documentation: https://www.johnvansickle.com/ffmpeg/
Host the static build on your server in same directory
$ffmpeg = dirname(__FILE__).'/ffmpeg';
$command = $ffmpeg.'ffmpeg -i audio.ogg -acodec libmp3lame audio.mp3';
shell_exec($command);
For batch processing files in folder:
for i in *.wav; do ffmpeg -i "$i" -f mp3 "${i%}.mp3"; done
This script converts all "wav" files in folder to mp3 files and adds mp3 extension
ffmpeg have to be installed. (See other answers)
1) wav to mp3
ffmpeg -i audio.wav -acodec libmp3lame audio.mp3
2) ogg to mp3
ffmpeg -i audio.ogg -acodec libmp3lame audio.mp3
3) ac3 to mp3
ffmpeg -i audio.ac3 -acodec libmp3lame audio.mp3
4) aac to mp3
ffmpeg -i audio.aac -acodec libmp3lame audio.mp3
As described here input and output extension will detected by ffmpeg
so there is no need to worry about the formats, simply run this command:
ffmpeg -i inputFile.ogg outputFile.mp3
I had to purge my ffmpeg and then install another one from a ppa:
sudo apt-get purge ffmpeg
sudo apt-add-repository -y ppa:jon-severinsson/ffmpeg
sudo apt-get update
sudo apt-get install ffmpeg
Then convert:
ffmpeg -i audio.ogg -f mp3 newfile.mp3
For batch processing with files in folder aiming for 190 VBR and file extension = .mp3 instead of .ac3.mp3 you can use the following code
Change .ac3 to whatever the source audio format is.
for f in *.ac3 ; do ffmpeg -i "$f" -acodec libmp3lame -q:a 2 "${f%.*}.mp3"; done
You could use this command:
ffmpeg -i input.wav -vn -ar 44100 -ac 2 -b:a 192k output.mp3
Explanation of the used arguments in this example:
-i
- input file
-vn
- Disable video, to make sure no video (including album cover image) is included if the source would be a video file
-ar
- Set the audio sampling frequency. For output streams it is set by default to the frequency of the corresponding input stream. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options.
-ac
- Set the number of audio channels. For output streams it is set by default to the number of input audio channels. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. So used here to make sure it is stereo (2 channels)
-b:a
- Converts the audio bitrate to be exact 192kbit per second

VBR Encoding:
ffmpeg -vn -ar 44100 -ac 2 -q:a 1 -codec:a libmp3lame output.mp3
If you have a folder and sub-folder full of wav's you want to convert, put below command in a file, save it in a .bat file in the root of the folder where you wan to convert, and then run the bat file
for /R %%g in (*.wav) do start /b /wait "" "C:\ffmpeg-4.0.1-win64-static\bin\ffmpeg" -threads 16 -i "%%g" -acodec libmp3lame "%%~dpng.mp3" && del "%%g"
