doomlordis Posted August 30, 2005 Report Share Posted August 30, 2005 (edited) Ok i was keen to examine the MP3 playback of the RH710 and have had a strange result:First the original wav (white noise) analyzed by eac[attachmentid=777]then the mp3 with drop off at 19 as expected.[attachmentid=778]now the same mp3 recorded from my player (small amount of silence at begining of track) [attachmentid=779]i am confused, i am no expert but it looks like the volume has been reduced across the whole spectrum (european cap? lack of digital amp? - the wav recorded from md is quieter) and seems flat without drop at 19???? - opinions welcome as i am no expert and am willing to do test again with different frequency analyzer.If this is correct then the RH710 may be the best option for mp3 playback on H-MD at the moment.

greenmachine Posted August 30, 2005 Report Share Posted August 30, 2005 Looks like you'd have recorded the soundcards' - (or whatever you've used as the capturing device) self-noise only. Try again with real music. Quote Link to comment Share on other sites More sharing options...
doomlordis Posted August 30, 2005 Author Report Share Posted August 30, 2005 (edited) i recorded from line in and can listen to the sample fine. What do you mean self noise?Here is the wav recorded from my rh710 playing the white noise 256kbps mp3, can someone else have a look?[attachmentid=783]whitenoisemp3walk.wav Edited August 30, 2005 by doomlordis Quote Link to comment Share on other sites More sharing options...
greenmachine Posted August 30, 2005 Report Share Posted August 30, 2005 If you use noise, you won't know if it's actually the one you've tried to transfer or if it's been introduced by some other components via analog recording. Try real music or something like a sweep tone. Also, what's the use of comparing the volume to an analog recording?. Quote Link to comment Share on other sites More sharing options...
doomlordis Posted August 30, 2005 Author Report Share Posted August 30, 2005 ok just recorded beck fine with no problems so i think sample is ok. Quote Link to comment Share on other sites More sharing options...

greenmachine Posted August 30, 2005 Report Share Posted August 30, 2005 But you're expecting your soundcard's line input to be perfectly linear. For a meaningful comparison you need the analysis of a sample in pcm and mp3, untransferred and transferred. Quote Link to comment Share on other sites More sharing options...
doomlordis Posted August 30, 2005 Author Report Share Posted August 30, 2005 I have retested using rightmark audio analyzer and the earlier result is wrong , as you can see the drop off at 3 is apparent with this test.Oh well , sorry to raise any hopes...[attachmentid=784] Quote Link to comment Share on other sites More sharing options...
doomlordis Posted August 30, 2005 Author Report Share Posted August 30, 2005 As a comparison here is my HD5 playing same mp3 with volume at full , line out off.[attachmentid=785] Quote Link to comment Share on other sites More sharing options...
doomlordis Posted September 3, 2005 Author Report Share Posted September 3, 2005 THis is the nearest to flat response you can get with RH710 using hacked equalizer ( i have tested a lot!)Settings on equalizer are all normal except 4khz up 1 notch and 10khz up 2 notches.[attachmentid=821] Quote Link to comment Share on other sites More sharing options...
