I have read various postings from different users who have used Rivendell. I have received some inquiries about Rivendell and I would be interested in obtaining a couple of audio files that are from a Rivendell system. Would someone who uses Rivendell be able to provide a few audio files that I can listen to, etc, so I can determine sound quality, etc?

I can provide you with whatever you need, but I don't think that an audio file out of my system is really going to be especially useful. Rivendell uses standard PCM16 and MPEG Layer 2 formats for audio storage (for the latter you will need an AudioScience adapter that supports MPEG due to licensing issues). Eventually, the project will also support OGG. Nothing is proprietary; everything is standards based.
The built in CD ripper utilizes a Linux package called cdparanoia, which is easily one of the best on any platform, because of how thorough it is with packet checking and rechecking. I have been using Rivendell on-air for well over a year and have never had any quality related audio issues.
As with any system, the quality of the audio is only as good as the source material. Where is your audio coming from? CDs? The Internet? Satellite?

Most, if not all, of my machines have audioscience cards. I get my music from a variety of sources including CD and the net but no satellite.
As for the sample audio files, audio quality is one of my biggest fears. If I can validate that to those with the money that the audio quality on linux using Rivendell is at the same level as the audio quality on windows.
In addition, we have some external parties that develop software applications for us (local business in small town type of thing) and when we approach them about running their software on Linux, I would like to be able to show them some sample audio files from a Rivendell system.

You need not fear. Audio is audio. The fact that the playout is originating from a system running Linux is really pretty irrelevant. If you are going to be using ASI adapters, then you have even less to worry about.
There are more important issues that should be consuming your time instead, such as "How am I going to learn a whole new operating system in such a short amount of time?".

I have no idea what you just said. It's worse than vague.
I will add that just because you switch the automation/playback to Linux doesn't mean that every computer in your office needs to switch as well. We use Linux and Windows here, and many days I work from a Powerbook running Mac OS X. Only change what makes sense; this is not a zero-sum game.

The audio quality is almost solely hardware dependent. Linux uses the same codec algorithms as any other contemporary OS.
In the case of the Rivendell implementation, the decoding for MP* playback is offloaded onto the Audioscience cards. So whether you get good quality audio or bad from MP* files is going to necessarily be dependent on your hardware.
That's the beauty of Linux. The OS is designed to function basically independent of the hardware. You never have to do a complete reinstall if you change out a motherboard or other hardware device. You will, however, have to recompile the Kernel, but that does not require much effort and does not require the effort that a Windows system requires.
