Surround sound test files for every audio format
- seba_dos1 3y agoI don't get one thing - why would devalue your submission by typing "every" when it's clearly not true?
- happytoexplain 3y agoWhat a strange thing to be condescending about.
- dtx1 3y agoTrue, it's weird but this is missing major formats like auro3d
- globular-toast 3y agoPretty sure Ogg/Vorbis supports multichannel. I don't see that there.
- asylteltine 3y agoAuro3d isn’t a major format and it’s entirely dead
- nativeit 3y agoSome sort of CAD file for etching wax cylinders and vinyl masters would warm the smart-ass cockles of my heart.
- zer00eyz 3y agohttps://www.audioholics.com/audio-technologies/auro-3d-bankruptcy https://www.audioholics.com/audio-technologies/auro-3d-bankr... Isn't auro3d mostly dead/beta maxed?
- dtx1 3y agoSure, but it's something my receiver technically support
- teh_klev 3y agoBut no-one is shipping content with these long gone formats any more. My almost 20 year old receiver supports formats that have long since fallen by the wayside as well, why put any effort into them for test and diagnostics?
- CamperBob2 3y agoI was bummed that it didn't include 4-bit mono ADPCM, myself. Nothing else evokes my childhood with Ma Bell quite as effectively.
- seba_dos1 3y agoOld content still exists. Also, there are still SACD releases being made in 2023 (though whether it makes sense is another matter) and DSD is nowhere to be seen in this set of files either. That said, it's obviously impossible to include every audio format out there, so I don't expect it to do so at all. That's why I asked what's the motivation to write such thing, because it's a very weird thing to say in the first place. If it actually included some weird, exotic and outdated formats it could perhaps be excused, but apparently it doesn't even try to do that, so it really feels like clickbait.
- refulgentis 3y agoDude what
- seba_dos1 3y agoNobody's condescending here (except you, perhaps). I don't know much about audio formats myself, I clicked because I got curious of "every audio format", but got a pretty basic set of the most popular formats instead that's missing some formats that even a dummy like me knows that exist, so I'm genuinely curious why would someone add a completely unnecessary and confusing word "every" into that sentence instead of, say, "various". All it achieves is that it turns a useful submission into a lie.
- dylan604 3y agoThe LPCM5.1 is an M2TS file at @498MB while the LPCM7.1 is saved as WAV at only 23.2MB. That seems very strange unless the 7.1 is significantly shorter. That would be very odd decision. Seems to me that a library like this would be exactly the same audio source just saved as the different formats. Maybe I'm over thinking it, and just too OCD about making a library like this public for fear of this very type of criticism
- batch12 3y agoMaybe it's the collector's goal to eventually have every one possible
- asylteltine 3y agoThis is way more useful than people think thank you Google products have become so user hostile at the expense of their users. I literally cannot download this folder on my phone I have to “share” each one individually. I also can’t make an actual copy of the files without downloading and uploading so they save some precious space. Must be hard for such a small company

- crazygringo 3y agoYou're right that you can't download multiple files on the phone. (Whether that's a good decision or not I don't know -- generally whenever I try sharing multiple files in iOS apps it's wonky, where apps only receive the first file and throw away the rest, so it might be a broader ecosystem problem.) But just use your browser. Ctrl+A to select all files, hit the "Download" button, wait a minute for it to create a .zip file, and it downloads. Just tried it myself, works like a charm. (In past experience sometimes the .zip archive step fails -- if so, so just try a second time.) > I also can’t make an actual copy of the files without downloading and uploading so they save some precious space. If you're trying to make a copy to your own personal Drive, just select "Make a copy" from the context menu. That creates a copy (not a shortcut) in your Drive root folder, no downloading and uploading required. (In the mobile app that option appears only for individual files, but the Drive website allows you to do it for all selected files at once.) I just tried this now as well and it works perfectly. Or if you want to save space on your Drive, you can drag them to "My Drive" (rather than explicitly making a copy) and it'll create shortcuts instead.

- ShadowBanThis01 3y agoGoogle Drive is so rife with fraud and BS. First off, if you upload stuff to someone else's Drive, it counts against YOURS. Second, there's actually no way to let someone upload stuff to your drive. I needed a bunch of video footage from someone else's phone, but she couldn't upload it even though I gave her a link to a folder... because she doesn't have her own Drive. So BS #2 is to support BS #1. I don't remember if Google double-counts stuff "shared" with you, against your Drive and the sharer's. But I wouldn't put it past them. Unfortunately DropBox doesn't offer competitive capacity/price combos, and even worse they outright lose files. They lost an entire video job I uploaded for a client; gigabytes of files just disappeared for several days, and when they finally responded to inquiries they had no explanation. I had to sign up for Google just to get the job delivered (late).
- j-bos 3y agoCan someone explain the purpose and use of these files?
- raffraffraff 3y agoI used a tiny SBC and a 7.1 channel USB soundcard to upgrade a 15 year old Yamaha AV 5.1 "Dolby Digital" receiver (with toslink/spdif) to handle the latest codecs. The old receiver has a "6ch input" selector that doesn't do any decoding - just takes the 6 inputs, amplifies them and sends them to the speakers. I also use the extra 2 channels from the USB 7.1 audio to a 2nd stereo amp that powers the adjoining room. (This involves pulseaudio channel mapping). It took about 2 days to make sure that absolutely everything worked, including turning stereo into 5.1 + 2, and adding LFE to the adjoining room speakers so they didn't miss out on multichannel bass. Technically, I could map the extra channels from a 7.1 or 9.1 source into their nearest 5.1 neighbors, but I left that part disabled because I don't have any sources with that many channels. The most tedious part of the setup was proving that each source type was supported, and all the speaker mappings were correct. Test files are extremely useful and there's no one source for all of them. I spent quite some time finding these files for myself.
- red0point 3y agoCan you provide a bit more details to your setup (HE, …) - it sounds perfect and exactly what I am looking for at the moment.
- raffraffraff 3y agoI bought a MeLE quiet PC (little bigger than a pi but with case, x86, ssd, 16gb memory) and installed OpenSUSE Tumbleweed because I wanted a rolling distro. Installed kodi, mounted it on the back of a large monitor. Using a cheap Startech 7.1 USB audio on a long USB connection that takes it all the way to the Yamaha receiver. I've attached a 2TB HDD to the MeLE and that holds most of my stuff. There's a NAS in the attic too. For the pipewire / pulseaudio channel mapping I can go into the boring details if you want
- slimsag 3y agoWhat is the license of these files?
- hunter2_ 3y agoSuppose these were stolen from someone who established some sort of license. Then knowing that would be extremely useful. But suppose that simply isn't the case, and somebody just created the files and let them go. Is it problematic for there to be no license? The phrasing of your question (asking what the license is, rather than asking whether there is a license) suggests possibly yes. Genuinely curious. Should things that legitimately lack a license be treated as if they have an infinitely permissive license or an infinitely restrictive license or something in between?
- seba_dos1 3y agoMost jurisdictions on Earth are pretty clear that no license means no ability to use whatsoever (sans special cases like fair use), so you don't have to type "all rights reserved" - it's the default. Sometimes the act of sharing with intention for others to use creates an implicit license though, but the extent of such license depends on particular country's laws.
- lxgr 3y agoYou don’t need to “establish a license” to receive copyright protection in most jurisdictions (anymore). Unless they specifically grant a license to the general public (such as Creative Commons) or they release a work into the public domain (in countries that know the concept), the copyright is with its creator. This only applies to copyrightable works and there are many other edge cases, though.
- hunter2_ 3y agoI assumed these aren't copyrightable, based on the lack of creative work I discern in the recordings. Should've clarified that in my question.
