Opus for audiobooks etc
...bered. If Opus can do anywhere near as well, I think a lot of folks would be interested in using it for audiobooks and avoiding the patent jungle. The only comment I've seen about use of Opus for audiobooks was jmvalin saying in response to someone on his blog that Opus's ability to do fullband would be a key advantage here. This seems kind of counterintuitive to me- can people even ABX human speech at a 32 or even 24kHz sample rate from speech at 48kHz, much less hear a large quality difference? A number of audiobooks I've listened to have used 22kHz mp3s without being clearly ob...

High Frequency Hiss with Opus at 48 kbit/s
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi to everybody. First of all I hope this is the right place to discuss such an (nitpicky) issue. I've just been testing the current Opus release and for mere curiosity compared its performance to WMAPro with CD quality music at low bitrates (48 kbit/s). While Opus generally does a very good job, I found one particular example (a high pitched

running at 44.1K but with standard frame sizes
Hi all, I'm implementing the opus codec for a proprietary RF link (for fullband audio) and want to make sure I understand something. The link is currently running at 44.1KHz - realtime (i.e. streaming from an A/D at one side, ultimately to a D/A at the other). Rather than muck with all the infrastructure, I'm looking at how to run Opus at 44.1K. I have flexibility in the f...
