Non-MP3 Codecs?
Vanth Dreadstar asks: "While
MP3 is okay, I have begun researching other codecs that would be
suitable for my home music use. Lossy codecs such as Ogg
Vorbis, AAC,
and MPC all seem to have promise, not to mention the lossless codecs
such as Shorten
(otherwise known as .SHN),
LPAC, and FLAC.
I would like to know what non-MP3 codecs people are using out there,
and why."
lossless compression is the only way to go.
* Much better than OGG and MP3
* Picture perfect at 128 kbit/s
* Supported by hardware (unlike ogg)
* Next version (Corona) will sport 5.1 Dolby, 24 bit samples, 96khz sampling rate, better compression.
* Existing hardware will update firmware to support Corona
thats because microsoft pays them to say it sounds better.
No, really! Windows Media kicks the hell out of any other lossy encoding format this side of ATRAC (Sony's MiniDisc codec). 128Kb/s WMA *smokes* MP3's encoded under 200Kb/s. Score one for the Evil Empire.

The formats are called lossy because given a compressed file, you cannot perfectly reconstruct the original data file. This applies to both #4, and #5.
I am relieved to know that you are totally deaf, and thus cannot hear the difference between a badly encoded mp3, and a SACD. If you wish to remedy this problem, you might want to consider getting new batteries for your hearing aid.
For the rest of us using high-caliber playback systems (clue: this means NOT Bose, NOT Panasonic, NOT Sony, NOT Yamaha, NOT Klipsch), and actually have some sense of hearing, the difference between those so-called lossy files and the original is night and day.
(clue #2: high-caliber DOES mean:

Sonic Frontiers
Dynaudio

Avantgarde

Catching the drift yet?
Read the source Luke! - The reference source code _is_ readily adapted to fixed point. One company has done so already.
I will leave it up to the reader to search the mailing list at xiph.org to find the (recent) thread regarding EXISTING fixed point code.
