Ricci Posted May 1, 2014 Report Share Posted May 1, 2014 Sounds great to me. This might finally give me something to replace Soho54's disc. If I think of anything I will let you know. Link to comment Share on other sites More sharing options...
maxmercy Posted January 20, 2015 Author Report Share Posted January 20, 2015 I have made a breakthrough in the development on the disc, and it may be possible to put 7.1 Audio on a DVD-5 at 24 bit depth and 48kHz rate. That would make this disc MUCH easier to create, but there will likely be an 'LF Only' disc as well as an 'LCRS Only' disc..... I am currently using my prototype disc to measure what gear can even process a 7.1 worst case LF scenario, using my soundcard as an oscilloscope. So far, two mid-high end pre-pros cannot do it without TERRIBLY distorting the output wave. Will test an AVR soon.... JSS Link to comment Share on other sites More sharing options...

BeastAudio Posted January 26, 2015 Report Share Posted January 26, 2015 Wow, I really like this idea Som time ago I was involved or initiated a thread @AVS with regard to finding a worse case scenario scene,... whereby gain stages could be set, speaker/sub systems tested etc, ie the most demanding scene known. I examined several of my DVD/BD releases in a crude, spectrally weighted method of amperage drawn on a sub amp, at a given level. My methodology proved a bit too crude,..like non-starter crude, fun nonetheless. I'm down for one. DUDE! Where ya been? I thought I sent an email to the right address a while back but I never heard a response. Hope all is good with you man Link to comment Share on other sites More sharing options...
sterlo Posted February 8, 2015 Report Share Posted February 8, 2015 Hi guys I'm sorry to hijack this thread but, I was wondering if this blu ray/DVD you refer to will help me also ! I am looking for something that to me appears simple but, I'm unsure where I can get it : A disc with 'LFE channel' test tones, that plays individual low-level frequencies on this channel (ie Track 1=12.5hz, T2=16Hz, T3=20hz), 25hz, 31.5hz and so on. The reason I want this is, I don't know of a disc that plays these frequencies on the LFE channel. I have the Hsu/Bas test CD that has tracks from 16hz up to 250hz, but it's not 5.1 encoded so therefore, impossible to measure a subwoofer's performance/room response on the LFE channel. I have Digital Video Essentials but this appears to only have a "rolling" track that quickly goes from 16-250hz in 20 seconds ; impossible to measure output at individual frequencies. I have the original Video Essentials (1997) also, but this doesn't seem to have LFE hz test tracks either (16-250hz). Is there a commercially available DVD/BD that has tracks 16-250hz for the dedicated LFE channel? Or is the disc that is the subject of this thread the only disc available? =). I'll buy whatever works !! Thanks ! Link to comment Share on other sites More sharing options...
maxmercy Posted February 11, 2015 Author Report Share Posted February 11, 2015 Try AVS with the 5.1 channel Audio Test DVD. Should be a sticky in the DIY Speakers section. This was intended to augment it with lossless 7.1 Audio. JSS Link to comment Share on other sites More sharing options...
Infrasonic Posted February 12, 2015 Report Share Posted February 12, 2015 DUDE! Where ya been? I thought I sent an email to the right address a while back but I never heard a response. Hope all is good with you man I hope he is alright. Haven't seen him around for a long time. You replied to a comment of his from 2013, btw.

Ricci Posted February 12, 2015 Report Share Posted February 12, 2015 Might be time to send that snail mail Max if you still have the address for him. Link to comment Share on other sites More sharing options...
