Or SoX , or r8brain . Sox is commandline and has a plethora of filter settings , can take some reading to find proper settings some of the recommended defaults are good .
Off topic: SOX is often used in a sub genre in audiophoolism , to up convert on your computer before sending it to the DAC . The caveats are the following IMO . Due to SoX enormous flexibility , you find a wonderfully setting that sound so good , but the fact is that you managed to make a filter with clearly audible and measurable artefacts :P ( adjust your treble control -0,5 dB instead ). Your DAC or processor are not agnostic to samplerates and actually perform different with different input ? Your server side up sampling serves as a work around to defeat a defect in the DAC , are you solving the rigth problem :P A variant is that the DAC's own up sampling sucks ( Archimago measured an Asus DAC with clear problems ). Why I weared off topic is because I used sox to make my own test files ( and r8brain ) once and found an astonishing amount of disinformation . I also sugests hydrogen audio as a good forum to get balanced info on the subject . I took a selection off well recorded music that I was sure off was recorded digitally in 24bit 96k or better as a starting piont and made my own test files , this was very interesting . IMO you can't use >40 year classic rock recordings to test this . The "intrisinic" sound quality is such that any modern format can code the content fully . The frequency response is so limited that 44.1 kHz sampling is more than enough , the sample theorem rules here if the signal you sample is bandwith limited you don't get anymore information by sampling more often than needed it's simply redundant , this is a fact not a matter of opinion . The noise levels are so high that 16bit is more than enough especially if properly dithered , I'll bet that 13bits dithered would be ok with many of the classic rock recordings . However the hirez version , can be a much better version than previously released on any format ,so they are still valid . But due to the state of this hobby the only way to sell this is if you also can you can slap on a "hirez" sticker on the box 24/96 or DSD. Previus "remastering " attempts for the CD media has not exactly helped ,they are often actually worse than the original release, this is a massmarket adaptation to the compressed sound that is in rigth now :/ ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=98591 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
