Why convert MP4 to MP3?

Converting MP4 to MP3 extracts the audio track into a smaller, widely supported file that is easier to stream, download, and play on devices that do not support video.

Does converting MP4 audio to MP3 affect quality?

Yes, because MP3 uses lossy compression. Starting from a compressed MP4 audio source, the conversion may reduce audio quality further.

Can MP3 files support multiple audio channels like surround sound?

No, MP3 mostly supports stereo audio and offers limited support for multichannel audio compared to newer formats.

Be aware that converting compressed MP4 audio to MP3 is lossy and may reduce sound quality
Consider the bitrate setting for MP3 to balance file size and audio quality according to your needs

Limitations

MP3 encoding uses lossy compression that discards some audio details, potentially affecting quality
Converting from an already compressed MP4 audio track (often AAC) to MP3 may lead to further quality loss
MP3 supports only stereo audio and lacks advanced multichannel and metadata features available in newer formats
MP3 is less efficient than modern codecs like AAC or Opus, requiring higher bitrates to achieve similar quality
