Sony_Fan Posted October 26, 2006 Report Share Posted October 26, 2006 I just noticed that on some music transfers from CD to my RH10, there is distortion in some of the music. I only record from pre-recorded CDs, no CD-R. Is the distortion caused by:- The CD- SonicStage- Bitrate (Hi-SP)- RH10??? Quote Link to comment Share on other sites More sharing options...

Sony_Fan Posted October 26, 2006 Author Report Share Posted October 26, 2006 Is it present when playing back through sonicstage?I take it you are ripping and not recording real time?Yeah, I'm ripping using SonicStage 4.0 The distortion is more present during the louder parts of a track. Some of the softer CDs from the 80's seem to have no distortion. I'm starting to think the distortion is being caused by a CD with high volume. I was ripping "One Heart" by Celine Dion.

ZosoIV Posted October 26, 2006 Report Share Posted October 26, 2006 Lossy codecs can cause sometimes clipping on loud peaks that are close to 0dB - even if the actual peak on the CD is less than 0dB. IIRC, it has to do with how scalefactors are calculated. That's why when using MP3, for example, I always send my files through Replay Gain and set the peaks to 89dB - you might be able to do the same with Wav Gain and import the wav files into SS for encoding to ATRAC.

I would transfer MP3 to my Rh10, but they sound horrible. Quote Link to comment Share on other sites More sharing options...
doomlordis Posted October 26, 2006 Report Share Posted October 26, 2006 There is an obvious answer, it is not distorted it is Celine Dion... Quote Link to comment Share on other sites More sharing options...
Sony_Fan Posted October 26, 2006 Author Report Share Posted October 26, 2006 There is an obvious answer, it is not distorted it is Celine Dion...Be serious. What we need is ATRACgain software. Something as easy to use MP3Gain. Quote Link to comment Share on other sites More sharing options...
Sparda Posted October 27, 2006 Report Share Posted October 27, 2006 In my past experience, anything that sounds abnormal is because of the source. ex. I have this cd where I listen it through speakers and it sounds fine, but through my RH1 I can hear clicks and moderate distortion at 356kbps, I guess its because it is more defined?

Qwakrz Posted October 27, 2006 Report Share Posted October 27, 2006 (edited) Blame the record companies and their "Louder is best" compression techniques.Almost all the CD's released now have the dynamic range of a sponge pudding and are constantly pushing the upper limit on CD's, this causes them to sometimes clip (the crackle you hear) but because someone decided that the louder a song sounds the more sales they get from radio play thats what we have to put up with.When CD's were originally released they had a dB range set out to go from infinited upto +6dB to allow for peaks, music was supposed to sit around 0dB and only peak once or twice into a soft limit at +3dB and never the hard limit at +6dB. Now we have them constantly banging into the hard limit at +6dB and anything less than +5dB is counted as wasted volume.

This explains why CDs from the 80's and early 90's do sound better after being transferred to Hi-MD. Most of the CDs of the late 90's thru today are very loud and not very compression friendly.

Sparda Posted October 28, 2006 Report Share Posted October 28, 2006 I dont understand why louder is better, why not just turn it up? lol Quote Link to comment Share on other sites More sharing options...

greenmachine Posted October 28, 2006 Report Share Posted October 28, 2006 Hyper-compressed music is mainly "optimized" for the casual radio station listener, listening in the car and other noisy environments and for lo-fi systems, in other words, the average consumer. On higher end gear in quiet environments, it will sound mostly awful, particularly when listening for longer periods.http://en.wikipedia.org/wiki/Loudness_war Quote Link to comment Share on other sites More sharing options...
Sony_Fan Posted October 29, 2006 Author Report Share Posted October 29, 2006 Well, i think i found a way to reduce distortion from louder CDs. BEfore, I was just importing a CD with ATRAC3+ 256 at "normal" setting. Now, I import the CD as WAV files and then convert to Hi-SP and transfer to Hi-MD. It may be my imagination, but there seems to be less distortion. Quote Link to comment Share on other sites More sharing options...
