Re: Playing CDs with AmigaAMP

I don't think there's much overhead using sndfile.library.
16bit 44.1KHz stereo files aren't that demanding to
stream. As I wrote before, 1411Kbit/s about 140Kb/s.
Compare this to video files and you'll notice this is
no more than 1/4 of the bandwidth. Also the audio is
uncompressed so the CPU hardly has to do anything
when the system uses DMA.

Yes you can use the analog playback if you like.
It doesn't use the CPU at all, that's certainly a plus.
If playCD crashes the CD will continue to play though.

But if you hook up your computer to some serious HiFi
equipment you would probably want to send it out
fully digital. Even on cheaper HiFi systems it's preferable
to output digitally. Unless you have a really really good
soundcard.

Sound output should not be noisier, maybe a problem
with the sound player? Or atleast its plugin/datatype?

Also when controlling the CD drive with applications like
PlayCD you will not have the option of using a equalizer.
The sound is directed to the sound chip bypassing the
system.

Thats why I think there should be an API where the 3th party program can call AmiUpdate and say MY progam xxx is located at path yyy.. then AmiUpdate should have a DataBase with all the paths for all programs that support AmiUpdate, then it can fast and easy do version checks.

If this API gets done, it should then be incorperated into the OS IMO, maybe with a Remove program function to.

I'm not bad mouthing Rigo, for I think he has done a great job... but its really only usefull for OS components that have a fixed place on sys:, so see this an Enhancement sugestion for Version 2 :)

I'm sure you must have been using AmiUpdate for long enough now to realise that there is a mechanism for supporting 3rd party applications. This doesn't rely on a fixed path, but on a per-application facility incorporated into applications by the developer. Removing programs is not down to AmiUpdate really, but more to an uninstaller supplied by the application developer, although you can use Rollback to go back a version after updating.

More information can be found at www.amiupdate.net in the developers section.

You may also want to check the database contents section too, this will show you that there are a few non-fixed path applications already supported, with hopefully more to follow

"automatically mounts a device by startup"
grrr, scrap the "by startup" bit, i meant by plugging it in
OR on startup (when already plugged in)

mounter

yes, bad example (as it is already covered in the now
edited part of my first answer)

sorry bout that

Ok, further research: appeared that only not-booting-after-unplugging AC cable was cured by replacing the battery.
The sticky clock looks to go away after shortening the battey holder as per your advice

(just inserted the battey upside down).

Now hoping that all's well now...

Thanks a lot

Font install by installer/script

Posted on: 2007/10/2 23:00 #132110

Just popping in

I'd like to know if there is a proper way to install a new font to the system.

Manually I should do the followings:
- Start TypeManager select the source and system fonts drawers then install the font
- To be shown properly I have to modify hinter attribute to no hinter in TypeManager

Could it be done by a script somehow?
That would be nasty if I have to explain these steps to the user during install.

AFAIK TypeManager do not accept commandline parameters and doesn't have an arexx port.

Where are that font attributes are stored?

Thanks in advance for the help!

AmigaAmp used sndfile.library (m68k) to access aiff files, dunno how much overhead is there (mayne not at all when all io is ppc native), but I prefer the bultin analog playback of the CDDA. Why not use it. Setup freedb/cddb with playcd and viola!)

Edit: and analog playback is less noisy than extaction the sdda via software...

Point taken. Will check the previous one and see if it's ok and then if problem reoccurs, I'll short the contacts in the holder.

Meanwhile new battery seems to do the job.

Yes, ineffective it might be but OS4 hardware does not
support digital input if I recall. So the sound quality may
suffer. CD input is only analog on A1 hardware.

There does exist a digital input but it doesn't work or
isn't supported if I recall my conversations with DaveAE
correctly. On ?A1-C anyway. Sound cards may be different.

IMO to read it digitally and send it out digitally is
the best way of preserving the audio quality.
Btw I don't think streaming CDDA audio (1411Kbit/s) is
that demanding on the system.
