Description: Sample rate and bit-depth conversion

When you use different audio devices (phone, tablet, car audio, portable player, etc.) and software (players, editors), you are stumbled upon compatibility issues of music file format.
There are may be issues like:

When you convert audio files you need to save sound quality maximally. When lossless files are converted to other lossless ones without resolution altering, it is no problem. But any sampling conversion causes distortions. It is recommended to use an audio conversion tool that can cause minimum distortions.
