Convert AAC to MP3 with FFmpeg
FFmpeg can transcode audio between formats quickly. To convert an AAC file to MP3 using the LAME encoder, you can run:
ffmpeg -i input.aac -c:a libmp3lame -b:a 192k output.mp3
The -c:a libmp3lame
option selects the MP3 encoder, and-b:a
sets the target audio bitrate. You can also use-q:a
for variable bitrate (VBR) quality levels instead of a fixed bitrate.
Common pitfalls
- Ensure the input path is correct and quoted if it has spaces.
- If you hear artifacts, try a higher bitrate or use VBR via
-q:a 2
(lower is higher quality for LAME).
