What is MP3?
MP3 is the abbreviation for "MPEG-1 Audio Layer 3" and belongs to the family of the Motion Picture Expert Group (MPEG). MP3 files are marked with ".mp3".
An MP3 file is audio coding, i.e. that the original music file is compressed and converted. The music file is very heavily compressed, with only a slight loss in sound quality. Compared to the original music file, an .mp3 file only needs ten percent of the original file size. This compression is given in a compression rate in kbps. The higher the value of the compression rate, the better the quality of the MP3 file.
At a compression rate of 320 kbps you can hardly hear a difference to the classic CD sound. Digital music is saved and sold as an .mp3 file. This allows you to play music from a PC, Mac, iPod or MP3-Player without having to own a CD. Most streaming services also use the popular mp3 format for their services.
How does a YouTube converter work?
The conversion works like this: Copy the URL of the YouTube video you want to convert 2 mp3 from the browser address bar and paste it into the input field of the YouTube converter.
With a click on "Convert", the infrastructure of the online service processes the video and converts it with the help of ffmpeg. This usually only takes a few seconds and happens in the server background. The output format is ".mp3". You can define the folder for your downloads. In addition, the YouTube to MP3 Converter automatically names and tags the saved files based on the information stored on YouTube for each video.
When using a YouTube to MP3 converter, you always have to accept losses in quality. In this case, the quality losses are very low because the converter works with a bitrate of 320 kbps and a sample rate of 48 kHz.
