JUSTOGG DEVELOPMENT NOTES - 2/4/04

JustOgg runs fine on a Beige G3 266Mhz and a 6100 60Mhz.

A 68k version of JustOgg AIFF is included.

To try it out there are some ogg test files at these links:

> http://www.xiph.org/ogg/vorbis/listen.html
> http://www.vorbis.com/music.psp

If you run JustOgg 1.0 trash the previous JustOgg Prefs file, as the format has been changed for the release version.

Added a Fastload prefs item which bypasses the ogg file info and time checking and speeds up the loading of a lot of ogg files. The info and totaltime stuff is done on the fly when Fastload is enabled.

Also added a Background Menu item to JustOgg AIFF for slower macs so that if slow is selected JustOgg AIFF gives more time to the foreground Apps but decoding will be slowed down a bit.

On a 6100 60Mhz the slow menu item needs to be enabled for background converting but on a G3 this is not neccessary.

JustOgg AIFF version for 68k. For a 3:30 song encoded in Ogg format at 44100Hz, 51 Kbps, it takes about 8 minutes to decode to a AIFF file on a Macintosh Quadra 840AV.


JUSTOGG DEVELOPMENT NOTES - 1/15/04

Tested JustOgg with Ogg files ranging from 6000Hz, 8 Kbps to 44100Hz, 471 Kbps and they all play okay.

Finished JustOgg AIFF and the playlist editor as well.

Getting good playback speeds on a 60Mhz 601 (with the EQ off) even with 44100Hz, 300 Kbps Ogg files.


JUSTOGG DEVELOPMENT NOTES - 1/13/04

The EQ is only enabled for 44100Hz and 48000Hz Ogg files and streams due to high CPU usage.

Ogg files can be joined together, so a single Ogg file could contain multiple audio frequencies, channels, and/or data rates. For instance, an Ogg file could start out at 22050Hz Mono but end up at 48000Hz stereo.

JustOgg handles these combined Ogg files okay. The JustOgg AIFF decoder creates a new AIFF/WAV file if it hits a different frequency or channel number. So for the above combined Ogg example it would create 2 AIFF files one at 22050Hz Mono and the other at 48000Hz stereo.
