Question

If an MP4 video with AAC audio is converted to MP3, will the resulted MP3 file lose quality?

Answer 1

Not exactly, however, it will have a bit of loss on the pitch & bass at places.

Will advice to first convert the mp4 to aac & then to mp3, that way it will have the super quality intact, as that is what I generally do, while trying.

Hope this helps.

Cheers!

Answer 2

You can convert an MP4 video to MP3 but only up to 320 kbps which is the highest quality for this type of file. Also, to have a decent sound, the MP4 needs to be encoded at a high rate because otherwise you will have an MP3 file of low quality.
