How to get audio in sync using OBS

Wednesday, March 28th, 2018 | Activities, Gadgets, Insights, Tech-savvy | No Comments

I started streaming on Twitch a while ago and the setup for a decent stream can be tricky at times. One of the biggest issues I had was audio sync or to be more precise, the absence of it. 😉

I use OBS, a free and pretty powerful piece of software. After a few streams I added music to the gameplay, but when I was humming/singing along, I was off. A bit, a few milliseconds, but I could not find a way to get rid of the issue. So I started thinking … there is a “processing pipeline”, from the computer that plays the music, to the headphones, into my brain and out of my lungs into the microphone. I figured that’s where the lag came from:

Lucky me OBS lets you add and subtract delays to each audio source (even though I have a hard time understanding how you can shift a sound source into the past … maybe by implicitly adding a delay to all other sources?). So how did I find out the “exact” delay? It’s pretty tough, ears only will be not good enough.

So here is what I did:

  • recorded while some audio was playing (e.g. Massive Attack – Teardop) and used a drum stick and a practice pad next to the mic hitting the pad to the music omitting every third stroke so you don’t get used to your rhythm and stick to the song’s timing
  • exported the audio and measured the milliseconds between the real snare and my stroke using an audio editor (i.e. Audacity) – with “Teardrop” they are pretty easy to spot
  • open “Edit” -> “Advanced Audio Properties” and change the “Sync Offset” of your audio source accordingly
  • rinse repeat, as for some reason I had to do this a couple of times before I got it spot on

This got my singing in sync to the audio that got played. (The lag can also be influenced by changing buffer sizes, but I didn’t want to fiddle with these.)

Now the only thing that is still annoying me: I am not lip-sync on video. I still have to figure out whether there is an option to add/sub delay to the video source as well. Just saw there is a filter available in OBS, but it can only add delay, not sub it. Might play with that as well and hope to come up with a “picture perfect” audio video face-cam mic setup at some point 🙂

Let’s try beef 3

Friday, July 21st, 2017 | Activities, Food, Insights | No Comments

A friend of mine told me there is something like “reverse bbq” – first, cook the meat in an oven at the desired heat and when it is done let it kiss the sizzle zone of your bbq. Okay, this is my try.

I was shopping and saw this T-Bone steak.


Put it into the oven for 20min at medium rare temperature. I was not overly happy with the result, as my oven is shit so I cooked it longer and hotter as I intended in the first place.


But the bbq was hot by then 😀


And after another few minutes.

I had a late night dinner. I did not like it too much, I guess the beef steak is still my favourite meat. Right now I am fed up with red meat. I opt for Schinken Krakauer again at the moment. Yummy left-over sausages!

Let’s try beef #2

Thursday, July 6th, 2017 | Activities, Food, Insights | No Comments

This time I just bought a steak and grilled it. No frills.

The steak. A regular beef steak, I thought I can hardly foobar the most standard beef available.

Grilled. Seasoned. Served. 😛

Medium rare. Yes! \m/

It worked. Even though the meat quality itself was somewhat subpar (supermarket meat counter) the outcome was just what I wished for. The days of shitty minute steaks from the discounter are definitely over. I may stick to the occasionally sausage though (just love my Schinken-Krakauer) but no more cheap meat for me.

Let’s try beef #1

Saturday, July 1st, 2017 | Activities, Food, Insights | No Comments

I recently attended Santos Pure Beef seminar – which was great yet I can hardly say I was able to absorb all the meat cutting techniques let alone become a bbq sensei. This is my first attempt to bbq something else than sausages and minute steaks.

The meat I wanted to buy was not available (Teres Major), so I bought the cheapest part that still looked decent, a “Bürgermeisterstück” aka Tri-tip – in case I foobared this one it would not be too much of a loss. That whole lump cost €8.99.

The seasoning was easy. Just some salt and pepper.

Maxed out my grill at 350 °C (~660 °F).

Cross grillage brandings. (Couple of minutes each side)

So, this is the result. Looks great from the outside. (30 minutes, indirect, one burner on minimum flame ~ 120 °C)

Unfortunately I overcooked it. It was in between medium well and well. Bummer. But hey, it was my fist try and the taste was still very good 🙂 Next time I might only bbq the outer parts and use an oven at ~80 °C for maybe 20 min to finish it.

Biking to Stoned From The Underground 2014

Thursday, August 21st, 2014 | Activities, Music, Sites | 2 Comments

From my point of view Stoned From The Underground is pretty much the closest thing to the perfect festival. It’s still small, it’s in the summer, you can park next to your tent and you have a lake to swim in just next to the camp ground and stages. And obviously it’s stoner, doom and psychedelic rock driven – just my cup of tea.

For various reasons it seemed a good idea to ride by bike to the festival. I love riding the bike, it gets you close to nature and your limits if you want to. The scenery of Hessen and Thüringen really blew my mind, I did not know how beautiful the rural eastern parts of Germany really are. Hainich National Park and its Rennstieg were awesome. Savage, dark and mysterious.

Anyway, here are a few shots of the bike trip and the festival.

I hope I can make it again next year. This time I will not start near Kassel, maybe Frankfurt, so I can approach from the south west to see even more of beautiful Germany.

Wild camping – my maiden voyage.

Tuesday, December 3rd, 2013 | Activities, Gadgets, Photography, Sites | No Comments

I have recently upgraded my camping gear, so did a friend of mine, and now it’s pretty much winter proof (no more freezing while sleeping at Freak Valley‘s windy camp site!). We both wanted to test drive our stuff in the wild, so we figured a night’s out around the freezing point should do the trick. Weather forecast said it was gonna be dry with the lowest temperature around nill. Perfect!

The site was nice, mossy ground yet slightly slopy and the highway is in pretty close proximity which resulted in faint constant noise. Nevertheless the trip was awesome, we had clear skies and a few beers in the wild. I guess this wasn’t the last time, even though the occasional Brokeback Mountain jokes were on us in the office the next day. Ahh, sweet envy 😛

Ein Brötchen in Zons. Lecker.

Friday, May 3rd, 2013 | Activities, Photography | No Comments

So, das schöne Wetter Anfang Mai musste ich ausnutzen – und welchen schöneren Grund gibt es nach Zons zu fahren, als sich ein deftiges Wurstbrötchen am Rhein zu snacken? 😛

May Day 2013 Рbiking Sch̦ller / Sambatrasse

Wednesday, May 1st, 2013 | Activities, Photography | No Comments

Just a random trip, this time off my beaten tracks. Wanted to check out the lime works and see for myself that this is hardly a place to fancy a swim – unfortunately. I also wanted to check out Schöller because I’ve been to Kindergarten there. No recollections though.

For the complete route and stats visit my RunKeeper profile.

Drumming like Animal!!
(This time multiple exclamation marks are just fine)

Tuesday, April 16th, 2013 | Activities, Misc, Music | No Comments

Tonight, my drum-kit got the worst beating so far. Animal would have approved.

I broke a stick on my mesh head snare for heaven’s sake! It was worth it though. (Guess I hit the rim at some point?!)

Props go to The Machine’s “Caterpillar’s Mushroom“. Dim the light, lean back and enjoy a pretty intense roller-coaster ride.

The take-off at 13:00 just blows my mind!

If you need a lift home after that I suggest you try Hills’ Master Sleeps. Farewell!
