Is there some software (ideally free and for MS Windows) which can compare the quality of two (or more) files containing the same song? It should be able to take into account the quality loss due to compression as well as the quality of the original sound source. Ie the following factors and maybe more:
- The compressions format, e.g. MP3 vs AAC vs FLAC...
- The compression settings, i.e. bitrate and whether it's variable or constant
- Artifacts in the original sound source, such as static in analog recordings, or scratches on CDs.
