Is this lossless?

Hi, I needed to check if a track was lossy or not, and i forgot how to determine it, i downloaded AnalFreq - can anyone tell me if this is lossless or lossy?

I'm no expert, but that's lossless. There is no big dropoff that would signal a lossy source.

thanks :D

Looks fine to me (i.e. lossless).
