Hi Albert. The praise would be high for Aac Plus on Live365 as the Aac Plus format is very good at delivering a decent sound quality at very low bitrates. This will not approach a lossless format and, if in the future you decided to go to another format, you would lose more quality in trying to convert from Aac Plus.
Here's a brief summary of the "messing" with the sound that Aac Plus does to achieve it's goal of providing cheap internet radio: AacPlus works by combining three technologies, each of which shrinks the size of an audio signal. The first is AAC, the Advanced Audio Coding technique that Apple licensed from Dolby for iTunes. AAC analyzes the sound and throws away any data it knows human ears won't be able to hear, which is a lot. Then, aacPlus adds Spectral Band Replication, which strips out all of the music's high frequencies and replaces them with a tiny bit of analytical data. AacPlus players reconstruct the highs as a mathematical function of what's left. As a final space-saving trick, aacPlus tracks are recorded in parametric stereo. Instead of a left and a right channel, one channel is the sum of the left and right signals (L+R), and the other is their difference (L-R). This takes up less bandwidth, and the player can easily flip the two channels back to the original left and right. Regards.
