Hello.
All three are lossy.
Sorry for your lossy.
Great spec-anal shots, though!
P.S. Frequency Analysis isn;t indicative of lossy data compression, one way or the other. Sometimes, if a certain codec rolls off the high end as part of it's scheme, you'll see a drop, but:
1) not all codecs do that
2) a drop off in freq response is not always indicative of the presence of a lossy audio codec.
Fallacy: all lossy codecs roll off high frequencies. <<<--- NOT TRUE
Fact: all lossy codecs remove chunks of audio to shrink the data file size.
- There are many cases where high frequencies may be rolled off in the analog domain and it just doesn't prove anything.
- There are many cases where high-quality lossy codecs leave the high frequencies intact (iTunes does this).
- You can ALWAYS see the chunks' holes after removal in a spectrum slice - around a 2-3 sec span. This is the best way to determine if a lossy codec has been applied. ATRAC won't be as severe as MP3.
