Hi nFORCE,

Your website was totally unreadable to me, what language is it in?

Also what does your project do?

Default Please, translate it

Hello nFORCE,

Please translate, at least, part values in cir.pdf file, because some of them are hard to read on pcb.

As I see from source and schematics it does what it should - play, pause, next, previous, stop, eject. It's the first time I saw only those routines without all mp3 related stuff

Is that your site. If it is, does it work OK (is it debugged)?

Thank You.

Smile cdrom or expensive audio transport

Is there any disadvantage to using a cdrom for audio cd playback?

I see creative has a IR remote model and I was thinking of putting it in a nice box rather than buying an expensive transport or building the homeoptics kit.

I disected a cdrom and removed the tray the other day. It worked fine as a top load transport. I havent tryed to get the digital signal off of it and I dont know if this is compatible with an conventional audio DAC.

Any ideas? Cant get a clear answer to whether good vs decent transports produce different quality data?

I'm sure someone will jump in here to say YES, but I just can't see how - I mean, if a CDROM gave you DIFFERENT readings (numbers, values) for different manufacturer's drives, then you'd have a real big problem, no?

From what Ive read there is correction software that will do some interpolation before the unit audibly misreads. The MArk Levinson site talks about the data getting clocked inacurately if the transports clock is not accurate. Then I guess the DAC might spit out a sound at the wrong time?
