Digital audio files can be divided into two groups: lossy and lossless audio formats. Lossy music files are appropriate for most digital audio players, software applications and do not occupy a lot hard drive space on your computer. Lossless files maintain the original audio quality of your music CD’s. In other words you can transfer your CD tracks to computer without any sound quality loss. Among the most popular lossless audio formats we can name WAV (Waveform audio files or WAVE), FLAC (Free Lossless Audio Codec), APE (Monkey Audio), WV (WavPack), lossless Real Audio files and WMA lossless and many others. These files preserve every bit of audio information, so they cannot be small like MP3 or AAC.

Compressed or lossy audio are small and convenient for practically any digital audio player, they do not need a lot of disk space, are easy to upload and share. The most popular compressed files that we deal with are for sure MP3, WMA (Windows Media Audio) and AAC (iPod audio). During compression process the audio files are losing least important audio info like very high and very low frequencies. In the result the files sounds a bit shabby. That’s because most audiophiles prefer listening to music in one of lossless formats.

Only few lossless audio formats are supported by digital audio players. WAV files can be played with Apple iPod Touch, iPod Nano, iPod Shuffle, Iriver P7, Cowon D2+, Creative Zen X-Fi, certain Philips and Sony models. FLAC files can be played with most Cowon digital audio player models, BlackBerry Torch, Samsung Galaxy Tab and some others. So, with a help of good converter software, there is a good chance to transfer you CD collection to the digital player and listen your favorite songs on the go.
