Quick question. I noticed in the streaming section of BAO, a "reduced" bitrate for FLAC encoder which sends out FLAC stream at around 500kbps. Is this still lossless? How is this different from the "lossless" bitrate? (which streams at around 900kbps) and Is this mode avaliable in a regular flac.exe encoder?
"Reduced" dynamically reduces the bit depth, based on where the noise floor is, in such a way that it isn't audibly changing anything. It is Leif's own implementation of the lossyWAV idea, and tends to be on the less aggressive side of what lossyWAV can do at default settings.
You can read more about lossyWAV here, which is somewhat relevant, especially in how the idea works with FLAC (and other lossless codecs).
http://wiki.hydrogenaud.io/index.php?title=LossyWAVThe reason Leif made his own implementation is because lossyWAV doesn't work well with composite MPX, and Leif wanted that feature when recording composite MPX. 🙂 It's useful for streaming as well though, so why not have it available.
