Variable Reverberation in the CIRMMT Multimedia Room of McGill University in Montreal
This video was recorded in the Multimedia Room of the Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT) centred at the Schulich School of Music of McGill University in Montreal, in October 2023. The 70-loudspeaker active enhancement system (Meyer Constellation) in the space can be used to extend the room reverberation or create other types of virtual reflections. The room also has variable sound absorptive treatment in the walls which can be let down to increase the absorptive surface area or pulled up to reduce sound absorption. The video shows an example with a long reverberation time (absorber area reduced and RT artificially extended with the interactive audio system) and then with a short reverberation time (absorber area increased and the audio system is turned off).

The video was recorded with an iPhone SE 2022.

Long Flutter Echo in Big Hall
zhlédnutí 8KPřed 3 lety
In this video, I’m clapping my hands in a big hall. The black surface is acoustically absorbent material. Even though it covers about 80% of the walls, the reverberation time in the space is very long. This is because of flutter echoes between the lower untreated parts of the parallel walls. After recording this video, I have metrologically assessed the space in more detail by measuring the roo...
Different Video-Mapping Projects after Kalma’s VJing Workshop in August
zhlédnutí 277Před 6 lety
The video shows some of the projects from participants of the last VJING AND 3D MAPPING TECHNIQUES workshop in Berlin. The workshop was held by Kalma at the GlogauAIR Project Space from 8th until 11th August and apart from common mapping techniques in MadMapper we learned about interactive video content creation in VDMX with real-time audio- and video-analysis from media files or sensors like m...

Naomi plays her Alt Saxophone in the Anechoic Chamber and in the Reverberation Room of the acoustic laboratories of the University of Salford: acoustictesting.salford.ac.uk/acoustic-laboratories/anechoic-chamber/ and acoustictesting.salford.ac.uk/acoustic-laboratories/reverberation-chamber/ Recorded in February 2016, after a lecture of the MSc Acoustics.

Kinect to Grasshopper to Arduino to DMX (part 3)
zhlédnutí 5KPřed 8 lety
This is an interactive light installation for the Arup office in Berlin. It was combined from different parts of excibitions we participated in (see also part 1 and part 2 on my channel). Now it is used as a gimmick to play around in the hallway of our office. The person in front of the LED wall can walk along the white LED box to activate the LED stripes. The distance to the LED box controlls ...
Kinect to Grasshopper to Arduino to DMX (part 2)
zhlédnutí 6KPřed 9 lety
This is an interactive light installation called “LIGHT MOVES” for the Arup Penguin Pool exhibition on July 25th 2015 in Berlin. The concept was developed for this event to show how you can create interactive lights with available technology which react on the presence or movement of people. Our motivation was to save energy and to reduce light pollution with this concept since it could be used...

Kinect to Grasshopper to Arduino to DMX (Part 1)
zhlédnutí 1,6KPřed 9 lety
This is an example showing the connection of the Xbox 360 3D camera with Grasshopper for Rhino using the firefly kinect function. To address the DMX LED spot I used the firefly serial write function in grasshopper to send values to an Arduino. On the Arduino I used parts of the tinkerit DmxSimple code with a conceptinetics DMX shield. The height of the left arm is the R-value, the height of the...
Recording a song in that quiet room would sound so crisp😂

Just for the sake of alliteration/assonance, they should call it the 'anechoic annex'.
big up salford uni
Like playing in the wardrobe.
went into an anechoic chamber once on a uni tour, its so quiet you can hear the blood in your ears rushing through them
I went into an anechoich chamber in an university and after 10 seconds, I could hear my heartbeat, the blood flowing in my neck through my jugular and aorta. I then turned my head to look towards the door, because i already wanted out and heard my neck vertebrae turning on the discs. Just be ready if you go, all i'm sayin' 😂
Lise Simpson tunes on Hit & Run.
I would love to record a song in that room. So dry
Sounds like a horn on a highway truck
no Auto tune no echoes just pure talent
I studied here and worked in both of those rooms!
It would be interesting to spend a little time in there, I wonder how much we use echo in conversation .
Anechoic chamber: You're done. You're done.
This needs to be used for digital musical creation. So much cool stuff
Need to try a vacuum chamber next !
Sounds much better in the anechoic chamber. I wish my room be that muffled, I would listen to the music for hours in there.
Nah. Fake. There's usually at least some echo on the microphone.
I think you might be stupid
You could also use a cathedral as a reverberation room I think
That sounds pretty groove to me baby
Reverberation ensemble
Looks like a gd Saw trap room!!
Cool how you can hear the pads
The Echo Chamber gives a multi-dimensional quality whereas the Anechoic Chamber makes it sound flat and dimensionless, both have their place, it's how one uses them and how much where, and when.
release set to 0
Have you ever played outside? The sounds disappears. No reflection.
That made my mouth dry.
Now do it with an accordion. And then try and get out of there alive!
i can do this with a synth
Used to get up early on Sunday mornings to go play my bari in the stairwell of the music building. Sounded awesome.
« It sounds horrible » it just sounds perfectly dry to me
How good would sound recorded vocals in the Anechoic Chamber 🤔
Dang it I don’t know why but hearing that flutter sends chills of pure satisfaction down my back 🫠
Sounds like a bad VST
honk
all the looney hifi idiots out there. forget the system u morons and build a room like this
Sounds so much clearer in the special room.
The audio of being on a video makes it difficult to discern the differences that you're trying to point out. Neet video though.
Well that's the beauty of our generation: We always have our phones with us to spontaneously record things :) I agree the audio is not the best but the alternative would have been that I didn't record it at all as the purpose of us being in those rooms was only as an introduction as part of our MSc Acoustics course and we had not planned to capture it on video/audio.
basically like using a mute
I like the reverb room much better than the Anechoic chamber .
This is why I pay for the Internet
In case this isn't sarcastic and you are interested in different room acoustical effects, check out my other videos. I have two more videos recorded in larger spaces with interesting reverberation.
Stop ad on your vide mate
i want to hear caleb arredondo in this thing
She is having so much fun!
Lot of the best jazz records from 30s/40s shound, by today's standards, like they were recorded in an anacoustic chamber
That is a trip!
Sounds exactly like being in a practice room lol
So basically, the acoustics in the chamber sucks. Got it. 👍🏻
I don't think it sounds horrible in the anechoic chamber at all. I don't know what she means! All the specificities if technique come out and are sharper, and it clarifies the timbre. I think it sounds cool.
As a synth player, who regularly hears everything I play very dry through headphones, I now COMPLETELY understand why artificial reverberation became such a BIG deal in early recording tech. You absolutely need to hear the room resonating and responding to the sound as part of it <or a virtual/synthetic analogous effect> to make the sound sound "alive" in the ways we are used to hearing sounds. Life ALWAYS has reverb on it when we hear it.
Completely right! Reverberation is very important for musicians and it needs to be provided either artificially via the monitoring headphones or from the room itself. The latter comes with the problem that you cannot easily reduce the reverberation afterwards. But with larger groups of musicians, it's often not feasible to provide good monitoring via headphones to everybody, hence, a live (reverberant) recording room is often used for those scenarios. I recently visited the CIRMMT Multi Media Room in Montreal, which is a large space in which the reverberation time can be changed for research purposes, via extendable absorptive surfaces and artificially via loudspeakers: www.cirmmt.org/en/facilities
True, but a reverbless tone has it's own charm...
kinda yes but no. just dont set your synth or sampler decay to zero. most of the time its better to avoid usage of reverb.
