timdog5000 Posted February 24, 2015 Share Posted February 24, 2015 My charter DVR in the advanced audio settings asked if I would want HEAVY,LIGHT or NONE-for compression. Also asks if I want STEREO or MATRIX for stereo output choice. Can anyone tell me which I should have these two settings set to? I had not realized these settings were even in here till tonight. The charter guy had the compression set to LIGHT and the stereo output set to MATRIX. Tried to Google it but not much info out there. Thanks for any replies. 1 Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted February 24, 2015 Moderators Share Posted February 24, 2015 I would think you would want to set it to None and Stereo. Others will chime in 1 Quote Link to comment Share on other sites More sharing options...

Sancho Panza Posted February 24, 2015 Share Posted February 24, 2015 That's how I have mine set. Quote Link to comment Share on other sites More sharing options...
Gnote Posted February 24, 2015 Share Posted February 24, 2015 You definitely want it on stereo and I would go with no compression but that is a personal preference. 2 Quote Link to comment Share on other sites More sharing options...
timdog5000 Posted February 24, 2015 Author Share Posted February 24, 2015 You definitely want it on stereo and I would go with no compression but that is a personal preference. What are the advantages or disadvantages of compression, or should I just listen to it all three ways and see what sounds best to me? Had I been missing sound by using compressed audio? 1 Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted February 24, 2015 Moderators Share Posted February 24, 2015 typically when you compress audio or video it is to reduce the file size but by doing so you have to throw away information in order to get the file size smaller so to me anytime use compression there is a loss whether it be audio or video 1 Quote Link to comment Share on other sites More sharing options...

violetgrey Posted February 24, 2015 Share Posted February 24, 2015 typically when you compress audio or video it is to reduce the file size but by doing so you have to throw away information in order to get the file size smaller so to me anytime use compression there is a loss whether it be audio or video In this context compression is not about file size but about dynamic range. Compression in audio attempts to reduce the difference between the quietest and loudest portions of the audio signal. This compression makes quiet things louder and loud things more quiet. My instinct is to always keep any kind of post processing compression off. Most TV programming will already be compressed to a certain degree and don't require any additional work. Movie programming may or may not be additionally compressed for broadcasting but, given the work that goes into creating a movie sound track, I would prefer to leave that untouched as to preserve the original presentation as much as possible. As far as Matrix vs Stereo goes; if you do not Matrix your sound you will not have access to any Dolby Surround encoding that may be available with those programs. This may not be a factor depending on what you watch or whether or not you have a surround sound system. Material that is native stereo will not be affected by having Matrix enabled, and any other programming will be processed into surround in accordance to it's program. 1 Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted February 24, 2015 Moderators Share Posted February 24, 2015 Thx for the explanation Violet. So in the case of a DVR, you are suggesting it's best to choose "Matrix" because that will allow it to pass the info as say DTS-Master or Dolby Digital? 1 Quote Link to comment Share on other sites More sharing options...
Sancho Panza Posted February 24, 2015 Share Posted February 24, 2015 Doesn't seem to make any differ with my system; passes DD one way or t'other; COMCAST. Quote Link to comment Share on other sites More sharing options...
Gnote Posted February 24, 2015 Share Posted February 24, 2015 (edited) I should have thought about this longer before I replied the first time. IIRC the Matrix / Stereo will only affect analog sound and any digital connection will pass through whatever raw data is available. The Matrix in analog would be psuedo stereo. As soon as I saw Sancho Panza's post . It jogged my memory . Edited February 24, 2015 by Gnote 2 Quote Link to comment Share on other sites More sharing options...

sarumhyll Posted August 28, 2017 Share Posted August 28, 2017 I was just fiddling with those same settings, and going matrix with no compression does seem to broaden the sound stage. Speaking of Charter DVR, is it possible to copy the movies to another drive/computer? Should be Hammer - nail head - finger - - - HIT!
