If there is anyone who The selection of what you hear at the soundcard output and what you record from the soundcard are different.

I patched the source after unpacking to ask for half the number of semaphores it wanted (16 rather than 32 I think). You also may want to add the patches from the author's web page to do the FFT-based click removal, but you will need to install the fftw libraries before gramofile will build. Also gramofile writes the WAV header when the file is created and does not update it when the recording is complete. The header says the file is 100 minutes long, which makes seeking in XMMS a little tricky if it is really only 5 minutes long. I tend to record a side into, say, side1.wav then check that I have some samples over 99% but no (or maybe 1) sample at 100%, so I am reaonably sure I am using the max range of values without clipping. Then I fix up the wav file using sox: sox side1.wav side1a.wav This rewrites the header to reflect the correct length. Then run the track split detector and create the side1a.wav.tracks file. Edit this and use XMMS to locate the true start and end times of each track - gramofile only gets it vaguely right. Then split the tracks and use CMF IIF to do the click removal. jim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
