"To determine the audio quality at low bitrates, listening tests were 
performed by the EBU (European Broadcasting Union) in 2003. For stereophonic 
audio, the listening tests show that
•at an audio bit rate of 48 kbps, HE-AAC offers good to excellent quality
•at an audio bit rate of 64 kbps it offers excellent quality. "

MP3 kiek minimaliai turi būti, kad nors kiek padoriau? 128 kbps?
"HE-AAC combines Advanced Audio Coding (AAC), Spectral Band Replication 
(SBR) and, since version 2 (or Enhanced aacPlus), parametric stereo (PS). 
The codec can operate at very low bitrates and is good for internet radio 
streaming. A 48 kilobit-per-second stream is considered to have higher 
quality than 128 kbit/s MP3. "
