Is all digital music compressed?
Basically yes. But there are two kinds of compression when saving the original audio to a digital music file. You may also have heard - lossless and lossy. For example, Apple Lossless and FLAC are lossless formats. The most popular lossy format is MP3.
Which one is better, lossless or lossy audio?
Lossless audio formats will keep almost all the information of the original file, which means there will be no data loss. That also causes the large file size. The lossy compressed audio formats are the opposite. So, depends on different uses, you may need the lossless file to enjoy full quality, or you prefer lossy compressed files for easier transfer.
Are MP3 files compressed?
As mentioned, MP3 is a lossy compressed audio file format. It can help you compress songs with CD-quality to a much smaller size without losing too much sound quality. For instance, you can get a 3MB MP3 file from a 30-megabyte song.
What is the best MP3 quality setting?
If you want the highest quality, you can set the MP3 bitrate as 320 kbps at 16 bit and encode it as low as 96 kbps. This is a great setting which can reduce the file size largely while keep the main quality.
How to know if a song is over compressed?
When the music file is over compressed, you will loss most data of the original file, even the important one. That will make the song harsh to listen. If you cannot even make it to the end, then it is over compressed.
