Since many lossy encoding algorithms (MP3 and AAC for example) involve a sharp low pass filter at around 20khz, does this has any effect on phase and impulse response? I don't really understand the effect of low pass filters on ringing phase shifts, but I suppose that a really sharp one would have some extreme effect.
(I request in advance to not make this thread a discussion about pros and cons of lossy formats, it's purely a technical question about this specific topic. Thanks)
