#surroundsound — Public Fediverse posts

I wonder sometimes if I like some shows and movies better than others because I have a full surround sound system in my living room.

Current "whoa" surround mixing examples:

- Alien:Earth S1E3 - last 5 minutes.
- Sinners - that music scene

Hoping maybe the #Fediverse hive mind has some ideas about a problem.

My old workhorse Onkyo AV receiver died a few months back, and I replaced it with a Denon AVR-S970H. And it's driving me nuts.

My #TV is old, from the final generation of plasmas. Great picture. Sound is okay, but it only understands stereo and mono in uncompressed or AC-3 formats. Anything else sent to it - different codec, or multichannel/surround - is ignored and you get no sound. But that's okay!

Most of the things I watch that have stereo sound I just want to listen to through the TV anyways - TV shows, old non-spectacle movies, documentaries, all that sort of stuff. When I have a Big Movie with a #surround soundtrack, that's when I want to listen to it through the fancy speakers and the #AVR.

With my old #Onkyo, this was easy: the receiver always played the sound through itself and also sent it to the TV. If I wanted simple stereo, I'd just mute the receiver. If it was a surround sound thing, the TV just ignored it.

The #Denon... doesn't do this. I have to configure whether to output the sound through the TV, or through the AVR. There's no option for "both".

Pink Floyd in surround sound. Super Audio CD /SACD. High resolution format of the past and are still being made. These (and DVDA) are as awesome as vinyl records are for analog but are digital's peak. #pinkfloyd #sacd #dvdaudio #dvda #superaudiocd #SurroundSound #music

The Blue Man Group's AUDIO album is one of my favorite multi-channel high res 192/24 audio albums that I have. The mix itself, the incredible highs, the insanely rich base. Completely independent tracks written for each speaker. It's unfortunate that 5.1 music never really caught on, though I am happy that most live concerts recorded today are in 5.1. #music #highdefinition #highresolution #SurroundSound #Surround #audio #dvdaudio #sacd

Ugh, I missed the trailer drop 2-3 days ago on YouTube and the theater near me only has seats on the sides of the first two rows.

A theater in South Miami has a perfect seat left, but that's too far to travel since I've already experienced the concert show on AppleTV with my 4K tv and 5.1 surround system.

It's awesome 👏🏿

I'd love to see this in IMAX, but that doesn't seem possible.

So in my quest to get Dolby Pro Logic surround sound encoding in Godot, I have stumbled upon the docs for AudioEffectStereoEnhance. It had no documentation until now with 4.4 coming out. But it appears to go about encoding matrix surround sound the same way as Dolby Pro Logic by phase shifting the rear channels. How exactly it does this is not explained and these descriptions are still not detailed enough, but I think I might finally be nearing the end of my quest for outdated surround sound lol

I will try to test this later and will report back if I find anything useful.

Lilbits: Intel Foundry to operate as a subsidiary, HTC Vive Focus Vision XR is a premium headset, and Bose unveils “Personal Surround Sound”

Setting up a surround-sound system at home usually involves arranging at least five speakers plus a subwoofer around the house. But Bose has introduced a new “Personal Surround Sound” system that lets you do it by pairing a soundbar placed by your TV with a pair of open-ear earbuds. Since the earbuds don’t cover your ears, they can act as rear speakers while still allowing you to hear audio […]

I'm not really a #car person but I am an minor #audiophile and I got excited when I spotted that according the the manual my car should be able to handle #multichannel #audio playback!

However in practice all I seem to be able to get when I try various 5.1 #SurroundSound test files are the front left and right, all other channels silent. So it seems to know their 5.1, but only playing 2 channels out of front and rear speakers.

Any car/audio people have any suggestions? #Skoda #Fabia 3 #Bolero

People of the fediverse, help me do:

I have quite a collection of 5.1 FLAC files, and some .dts and .ac3, of music albums recorded in #surroundSound. I used to be able to play these out to my amplifier with discrete 6-channel inputs from an Xbox with #XBMC, and later over HDMI from a raspi running # raspbmc

Nowadays I have Samsung Atmos soundbar and an #NvidiaShield Pro. What software can I use to play these files back now?

(a boost would be appreciated if you can’t answer yourself)

Today I learned that my #hearing / #AuditoryProcessing isn't getting worse - it's that #TV shows and films are now increasingly likely to mix their #audio for #SurroundSound, where the dialogue track is intended to come out of the speaker close behind you, so they tend to put it really quiet in the mix. Hence why I need to put subtitles on to follow dialogue on shows, but I never used to. Which is... bonkers, because who tf uses surround sound? Aren't we all streaming on our laptops?

Splitting a Surround Sound Audio File in Ubuntu

https://shkspr.mobi/blog/2015/07/splitting-a-surround-sound-audio-file-in-ubuntu/

See this update for a better way to do this.

Being mostly notes to myself and following on from my post on Quadrophonic files.

I have:

• A DTS album stored as a .WAV
• A .cue file with chapter markings

I want:

• The single large file to be split into individual chapters with one file per chapter.
• Each file to be multitrack (that is, to stay in surround sound)

It turns out, that there is no simple way to do this. There are tools to split stereo wav files by their cue sheet, but nothing for 5.1 files.

So, here's how I did it. This process uses mkvtools and avconv.

The Easy (But Fairly Manual) Way!

I can't find an automated way to do this from a cuesheet - so here's what you need to do.

A typical cue looks like

  TRACK 01 AUDIO    TITLE "Alice"    PERFORMER "Bob"    INDEX 01 00:00:00  TRACK 02 AUDIO    TITLE "Carol"    PERFORMER "Bob"    INDEX 01 04:38:14  TRACK 03 AUDIO    TITLE "Dolly"    PERFORMER "Bob"    INDEX 01 08:39:09...

Track 2 starts at 4 minutes, 38.14 seconds into the file. It finishes at (8m 39.09s - 4m 38.14s) = 4m 0.95s.

avconv -f dts -i original.wav -ss 00:04:38.014 -t 00:04:0.95 -acodec copy track2.wav

That is, avconv forced to use DTS, starting at 4.38.014 and finishing after 4m .95s, copying the codec into a new file.

Calculating Offsets

It's hard to manually calculate all the timings. One quick(ish) way to get them is by using cueconvert.

cueconvert -i cue -o toc cue.cue cue.toc

If you open the newly created .toc file, you should see something like:

FILE "track1.wav" 0 04:38:14FILE "track2.wav" 04:38:14 04:00:70FILE "track3" 08:39:09 04:38:57...

You can then use those timings as your -ss and -t values - remember to add the extra leading "00:".

Limitations

1. The files aren't tagged / named correctly.
2. It's a pain to calculate the timings correctly.

The Hard (But Somewhat Automated) Way!

Convert the .WAV to .MKV

avconv -i whatever.wav -acodec copy output.mkv

In some cases, avconv will think your 5.1 recording is stereo. Fix it by forcing the codec it detects.

avconv -f dts -i whatever.wav -acodec copy output.mkv

Create a Chapters File

MKVmerge require a specific format of chapter file which is different from a normal .cue file. Creating this will be a manual process.

CHAPTER01=00:00:00.000CHAPTER01NAME=Chapter 01CHAPTER02=00:05:06.03CHAPTER02NAME=Chapter 02CHAPTER03=00:10:12.000...

Save that as chapters.txt.

Add The Chapters to the .MKV

A single command for this one:

mkvmerge output.mkv --chapters chapters.txt -o withchapters.mkv

Split The MKV

There are a couple of ways to do this, I use:

mkvmerge withchapters.mkv --split chapters:all -o track.mkv

You'll now have track-001.mkv, track-002.mkv etc.

Limitations

At this point, we have two moderately annoying problems.

1. The files aren't tagged / named correctly.
2. The DTS audio can't be extracted properly!

That last one is rather a showstopper! For some reason, the .MKV files play back their audio properly. When trying to extract or convert it, all sorts of stream errors occur.

TODO

Either write a patch for avconv to get it to split by .cue - or write a small Python script to do everything automagically!
