Hard to imagine a big market. A bit bigger than imagined . Its them and some other similar outfit or lossy ?

Happy New Year everyone! Yup. No surprise about the paicity of actual hi-res music. For years HDtracks has been releasing upsampled music. And few of the recordings of course achieve anything close to needing beyond 16-bits if even that. Years ago, I wrote the article on "'Hi-Res Expectations' (http://archimago.blogspot.ca/2014/03/musings-high-resolution-audio.html)" and I see absolutely nothing has changed over the years. I wondered back then and still today just how much of this stuff they're actually selling... Hard to imagine a big market.

Re: [SlimDevices: Audiophiles] What sort of quality do people get when they download so-called "Hi Rez"
Yes this is a quite common case the existing master is 44,1kHz or sometimes 24/48 which seems to be the popular music standard some niche audiophile or some classical labels may use higher resolution but they are the exception . But it does not really help with much of thier content which is much baby boomers rock from the 70s even captured in glorious 384kHz or DSD that analog tape still has less resolution than reedbook 16/44.1 kHz . Now I make my piont :) the actual technical spec is completely uninteresting as soon as it is 16/44.1 or better . What would matter is which master they source . If you truly wanted to sell HD or Hi Fi versions of anything you would select the masters with great care ,curated by humans . Not just making sure the dowloadfiles have big impressive numbers. That would include asking labels to actually not send their latest remaster effort in some cases , these are sometimes plagued low dynamic range and accompanying loudness war problems . But something else that the aficionados of a certain work/artist preferrers . It could in some cases actually be the latest carefully made remaster so I dont dismiss all remasters. ( some goes for so called hifi streaming services, who just lets the labels upload whatever they fancy without any QC ) . I would truly be an imidiate custommer if some service or shop provided definitive versions of the music or choices if they are several well liked versions Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)
CLIPPING InguzDSP creates a few files in /usr/share/InguzEQ/, after you've set up Inguz there are 2 files of interest: error & log.txt. You can check for errors with: Code: cat /usr/share/InguzEQ/error It should give you no output at all. The file log.txt can get big and we're only interested in the latest data so we'll use 'tail' to just give us the end of the file and print any new information as it comes in: Code: tail -f /usr/share/InguzEQ/log.txt If there's clipping going on, it will print 'CLIPPING+' or 'CLIPPING-' and something along the lines of: Code: 20180105181413: 01:53:01:53:01:02 2387377 samples, 404442.711 ms (1610.266 init), 0.1335 * realtime, peak 0.865 dBfs We're only interested in the last bit, the peak-value, a peak > 0 means clipping. The log will also contain the following information: Code: 20180105181939: 00:04:20:16:cd:70 24/96000 PCM => 24/96000 PCM TRIANGULAR, gain -16 dB Once again, we're only interested in the last bit, the gain, if you're experiencing clipping you should adjust it. In the above example a gain of 1dB lower would already prevent the clipping. To adjust the clipping enter the following in a terminal: Code: sudo nano /usr/share/squeezeboxserver/Bin/i386-linux/InguzDSP.exe.config RESAMPLING By default InguzDSP will turn off when LMS needs to resample (except for MP3 & OGG-files). I've added extra profiles to Plugin.pm that allow for resampling and even upsampling. There are 4 extra profiles in there: template_FLAC24_resample: allows for resampling when necessary and spits out 24bit FLAC's template_FLAC16_resample: allows for resampling when necessary and spits out 16bit FLAC's template_FLAC24_upsample192 and template_FLAC24_upsample96: upsampling to respectively 24bit/192kHz and 24bit/96kHz InguzDSP uses 24bit filters and all processing is done in 24bit, template_FLAC16_resample turns it back into 16bit after the processing is done. On line 3596 of the attached Plugin.pm you'll find 2 extra if-statements checking for the squeezebox-model, you should adjust here if you want to use a certain profile. I've got a Receiver (which can playback 24bit/48kHz) so I've got it setup to apply the FLAC24_resample-template when the modelname equals 'receiver', and I've got a SqueezeLite-box with a soundcard that can only do 16bit/48kHz so I've got that setup to use the FLAC16_resample-template. You can find the model-name of your device on LMS-settings page. If you've already got InguzDSP set up, replacing the Plugin.pm-file and restarting LMS twice should take care of the settings but you might have to delete the file 'custom-convert.conf' in the same folder (/usr/share/squeezeboxserver/Plugins/InguzEQ/) before restarting. +---+ |Filename: InguzEQ_Plugin.pm_resampling.zip | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=24300| +---+ W0153R's Profile: http://forums.slimdevices.com/member.php?userid=44848 View this thread: http://forums.slimdevices.com/showthread.php?t=77084 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
