Well, assuming you can handle getting the proper channel tuned and sending audio to your line-in, it should be a simple matter of a cron job (cron being a root word for time, and the name of a linux command that runs in the background similar to Windows Scheduler) and your favorite command line recording program. Every distro provides some form of cron, and it seems each one is special in its own unique way. You should consult the manuals of your distro for specific advice, and I think I found a good place to start with mandrake here:

You may have to dig around more to find the exact setup you need, or perhaps some fancy GUI interface to the cron job file.

I'm really looking for a reason not to use Windows 98 and the "Total Recorder" application I registered a few years ago. This solution technically works, it allows me to record from Line In at a pre-scheduled time, without me having to be around to start the recorder.

The problem is that after about an hour of recording the WAV file develops pops and crackles, and starts losing sections of the recording. I don't mind a Mono recording and even that setting doesn't help.

I somehow think Linux might do a better job (and ext3 should manage the larger WAV files better than FAT32), but no one seems to be using the "record from Line In" option for recording radio like a VCR. Everyone's developing projects using hardware FM Radio cards, and I'm just not in that income bracket these days.

So how does one go about doing a timed recording in Linux? Assume that the sound hardware is already installed and working (KNOPPIX 3.7 detects the SoundBlaster PCI card with no problems). I'm probably going to use Mandrake 10.0 since I'm used to it. I'd still prefer a console solution, the machine is a PII-300MHz with 256MB RAM.

It seems to me that I remember that to be a problem with the WAV file format, and/or the file size reaching the point where it's no longer stored in RAM. You might try a different encoding.
