What does a lossless audio format do?
You may think that the word “lossless” is used for audio formats that don’t use compression at all. However, even lossless audio formats use compression to keep file sizes at an acceptable level.
Lossless formats use compression algorithms that preserve the audio data, so the sound is exactly the same as the original source. This is in contrast to lossy audio formats like AAC, MP3, and WMA, which compress audio using algorithms that discard data. Audio files are made up of sound and silence. Lossless formats are capable of compressing pause to almost zero while retaining all audio data, making it smaller than uncompressed files.
What lossless formats are commonly used for digital music?
Examples of popular lossless formats used to store music:
FLAC
Wav
A THE C
Lossless WMA
Impact of Lossless Formats on Music Quality
If you download a lossless music track from an HD music service, you expect the sound to be really high quality. On the other hand, if you convert low-quality music tapes by digitizing them using lossless audio formats, the sound quality will not improve.
Is it possible to convert a lossy song to a lossless song?
It is never a good idea to go from one loss to another. This is because a song that has already been compressed in a lossy format will always be like this. If you convert it to a lossless format, all you get is wasted space on your hard drive or mobile device. You cannot improve the quality of a lossy song using this method.
