What is lossless audio compression?
You might think that the word “lossless” is used for audio formats that do not use any type of compression. 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 sound, using algorithms that discard data.
Audio files are made up of sounds and silence. Lossless formats are capable of compressing the pause to almost zero while retaining all the audio data.
What lossless formats are used for digital music?
Examples of popular lossless formats used to store music:
FLAC
Wav
A THE C
Lossless WMA
Lossless formats and musical quality
If you download a lossless music track from the HD music service, expect high-quality audio. On the other hand, if you convert low-quality music tapes by digitizing to lossless audio formats, the sound quality will not improve.
Can you convert from Lossy to Lossless?
It is never a good idea to go from one loss to another. A song that has already been compressed into a lossy format will always be like this. If you convert it to lossless format, you will only get wasted space on your hard drive or mobile device. You cannot improve the quality of a lossy song using this method.
Benefits of using lossless audio format
Using a lossy format like MP3 is still the most common way to store music collections. However, there are clear benefits to building a lossless music library.
Perfect Music CD Backup
Lossless copy of audio files gives you a bit-accurate copy of the original music CD. This means that no matter what audio formats appear in the future, you will always have a perfect copy of the original.
