</div>Try something like this:<br>
<br>
mplayer -vc null -vo null -ao pcm:file=track.wav:waveheader:fast -af resample=44100:0:2 -benchmark foo.mpg</blockquote><div><br>Well I ended up finding out that ffmpeg handles this pretty well as well:<br><br>ffmpeg -i <infile>.mpg -f wav -ar 44100 -ac 2 <Audio_out>.wav<br>
<br>After that I pulled it into audacity which after a little learning curve worked quite well. On my first attempt I exported each "track" as a separate file which worked, but doesn't really allow for gapless burning. After a little more research I found out I could export to modified .wav file as a single file (spliced in a few places, normalized, and a few fade in/outs) and then export the "Label" track which with the help of a little utility, label2cue, created a .cue file.<br>
<br>Unfortunately, as much as I like k3b, it does something very bad here. It will read the .cue file fine but if I try to write to an image file, it does not create a .iso, it hacks up the .wav file into separate .wav files by track when I went to all the trouble in audacity to get a continuous .wav file. k3b does not appear to be gapless recording friendly. <br>
<br>I found a forum post which suggested using gcdmaster which apparently is the official frontend to cdrdao and supports gapless burning in DAO mode, but it does not appear to have a "write to image" option nor did it find my burner.<br>
<br>Anyway, that's where I'm at right now.<br><br>Richard<br></div></div>
