Bitrate guide
128 kbps is fine for speech. 192 kbps suits most music and mixed content. 320 kbps is the maximum for MP3, and only worth it if the source audio was high quality to begin with, because a bitrate cannot add detail that was never there.
MP3, M4A or WAV?
MP3 plays everywhere and is the safe choice. M4A with AAC audio is usually a little smaller at the same quality and works on phones and most players. WAV is uncompressed, so the files are large, but nothing is lost, which suits editing. If the audio in your video is already AAC, M4A can often be created without any quality loss, because the stream is copied rather than re-encoded.
Choosing a bitrate
For speech, 128 kbps sounds clean and keeps files small. For music or mixed audio, 192 kbps is a good balance, and 256 or 320 kbps are the high end. A higher bitrate cannot add detail that was not in the original, so there is no point picking 320 for a quiet phone recording.
Troubleshooting
The audio is silent or very quiet
The video may have no audio track, or the track is very low. Play the video first to check. A silent source gives a silent file.
It fails on a large file
Files over about 500 MB can exceed browser memory. Trim the video first, or use a desktop tool.
The sound is out of sync when I reuse it
An extracted audio file starts at the beginning of the video. If you add it back to the picture, align it at the very start.
Limits and good to know
- Files over about 500 MB can run out of browser memory on some devices.
- The audio quality cannot be better than the audio in the original video.
- Only use audio you own or have permission to use.
