Since i stumbled across my first CD with pre-emphasis i thought i'll report how i handle it.
I like the idea better to dither back to 16bit before storing it at most likely useless 24bit. The files are easier to use otherwise also. The only comfortable one-in-all solution i found on the net is waveemph but i nowhere found how it treats the outputfile exactly. So i choosed Sox, this little commandline tool realy does great meanwhile! I rip the whole CD to a single wav When we are at it it makes sense to volume maximize the resulting file but we need two steps to reach that goal. If anyone has a better idea i'd be thankfull. Although i have only 1 CD so far with pre-emphasis so it won't spare me much work :) Also dither is a must. Since we already lower the highs a lot i choose a noise shaped dither with lower energy in highs. First i run sox in.wav out.wav deemph dither -f low-shibata stat This will spit out a table with results. At the end we have "Volume Adjustment" Now we have the maximum value we can use for the volume. I subtract 0.001 from that maximum value to avoid any possible clipping. And the final step sox in.wav out.wav deemph vol 1.xxx dither -f low-shibata stat Watch the stat output if everything went ok and enjoy That's all -- Wombat Transporter -> RG142 -> Avantgarde based monoblocks -> Sommer SPK240 -> self-made speakers ------------------------------------------------------------------------ Wombat's Profile: http://forums.slimdevices.com/member.php?userid=4113 View this thread: http://forums.slimdevices.com/showthread.php?t=34336 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
