First of all, normalise your WAV files to make sure they peak to 100%. You'll now find that they probably still don't sound as loud as the files you've ripped from CDs (especially if those CDs are from about 1990 or later). This is because LPs are mastered with greater dynamic range than modern CDs, and so on average they sound quieter.
If you genuinely want your LP recordings to sound as loud as the CD rips, then the only thing you can do is apply some dynamic range compression, using a suitable audio editor. But be warned that this is a non-linear process and introduces some amount of distortion. If you just want your LP recordings and CD rips to sound equally loud, and are prepared to turn up the volume generally, then the best solution is to apply an appropriate amount of less-than-unity gain to the CD rips. use an audio editor to analyse the WAV files and discover the RMS level. Then apply a corresponding decrease in volume to the CD rip. (For example, if a CD rip has an RMS level of -15dB, and an LP rip has an RMS level of -25db, apply -10dB of gain to the CD rip). This process is for all practical purposes linear and will not introduce distortion. (For the nit-pickers out there: yes I know that there will be minor arithmetic rounding errors and the very quietest parts could fall into the quantisation noise, but modern CDs are so incompetently mastered that these very small artifacts will probably be inaudible). -- cliveb _______________________________________________ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
