If you're afraid of audio quality loss, typically 24 bit 48000hz sample rate 
are considered slightly beyond the human capable range of hearing. (... if not 
well beyond depending on who you talk to.)   CD quality, 16 bit at 44100hz does 
sound "tinny" (or metallic tin) to me.  Given that CD quality (eg. 16 bit at 
44100hz) standard was set quite some time ago for CD media storage limitations, 
was likely adequate for that time period of the 1990's.

If I do any audio recording, I will always use 24 bit at 48000hz sample rate, 
and save as PCM WAV.

Either way; the audio streams likely still experience some loss (at 24 bit @ 
48khz) while the stream is being digitized, as the digitization process is not 
absolutely perfect...  yet.

For me, I keep everything in PCM WAV format, and use OGG Vorbis for portable 
devices.  PCM WAV is likely the most compatabile format versus FLAC.  On the 
flip, file metadata is not really a standard for PCM WAV files, unlike somebody 
just mentioned as FLAC having no problems with additional file metadata.  
(Similar to PPM/PBM/TIFF versus PNG image formats, etc...)  File metadata 
embedded into PCM WAV files can be nightmarish or cause significant 
incompatabilities, but not also to further mention, UTF-8/UTF-16 can also cause 
further anomalies instead of using just ASCII for filenames.  (eg. Hardware 
vendor FAT16/FAT32)

I'm seeing more and more audio streams either resort to either "MPEG 1.0 L III 
cbr96 44100 j-s" if they desire license free audio streaming, or migrating to 
AAC/FAAC (MPEG-4) if they can handle paying a few licenses.  MP3 from what I 
understand has several patents, inhibiting adaptation by hardware companies and 
stream providers, etc.
