FLAC is a collection of both programming libraries and user programs. As a programming library, FLAC most certainly supports writing both files and/or various kinds of streams from any incoming audio. However, FLAC does not contain code to read every kind of input, so support for getting the audio from the radio requires additional code.
The FLAC user programs generally read pre-existing files, since that is something which is available on every system. As Josh points out, they also accept data from stdin, meaning that another program which reads audio can feed it to the FLAC user program using a Unix "pipe." In this kind of pipe, the data is not keyboard input, because it contains data that could not be typed in. Without writing code, you'll need to find a program that can get audio data from the radio and send it to stdout. If you can find something that does this, then you can use bash to pipe that output into the FLAC user program. Otherwise, you'll need to write your own program that reads audio data from the radio and creates a FLAC file to save the encoded data. The FLAC libraries make this *very* easy to do. But you need to find code that will read audio data from the radio. Most developer example collections include sample code that could read live audio data from a Soundblaster. Good luck finding what you need!

I'm confused. I saw this mentioned somewhere, but I don't understand how you can send an audio stream through stdin -- we are talking stdin, as in what is usually keyboard input from bash. Any suggestions on a good place to learn more about this? _______________________________________________ Flac mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac
