Quick Start Guide For Open Sound Meter

Thanks very much great guide!

Much love and great respect ❤❤
Thanks alot

great . i was just talking about this today. its like you always know what i need haha

Thanks

OSM is going to be the first software I’m going to install on the new iMac that comes tomorrow- before Tidal!

Awesome video! Another thing I would add in is showing the math source feature. You can show a power average of multiple measurements to get a better idea of the entire room. It’s under File > add math source

lol 300ms is like 100 metres

In your video your speaker is about 1 meter from the mic, how come you're getting 311 ms of delay compensation? that's 107 METERS of distance!

This is GOLD! So many people gate keep this knowledge. Even as someone who has been engineering for a while, I’m just now getting into deeper understanding of systems and this is so helpful.

How I want to use it. I am the technical manager /A1 at a venue. We have four spaces. The large room is professionally tuned, but the other three were done by ear and a tape measure.

it was my first time trying this the other night and i forgot to apply delay compensation and was so confused by the poor coherence. in the end there were too many people in the room and i wasn't responsible for the mix just the pa so i tuned it by ear with their interstitial music playing thru their mixer and their eq weirdness, worked out great in the end.

Thanks for the video. Tuning speaker systems is not my use case. Loved the video anyway.
I use Open Sound Meter (iPad & UMIK-2 measurement microphone) during live gigs for sound pressure level control. Open Sound Meter I have set set to present 3 types of information:
1:Top left: LAeq 15 min. to comply with the convenant 103dB(A)LEQ15 In the Netherlands.
2:Top right: RMS SPL A Slow to provide me with the actual sound level.
3: Bottom: Spectrum (handy to see exact feedback frequencies would they occur)

Challenging is to calibrate the UMIK-2 for sound pressure level (calibration file is only for frequencies). Any suggestions how to do that?

Tnx for video 💞 Please make more videos for Open sound meter.

The averaging on OSM is what throws me off. Typically for optimising a PA system using smaart 1 sec / 2 sec average times yield the best results. Seems to be impossible with OSM. And the LF coherence is always troublesome. Never settles. Great for a free software but might have to be careful using it to align a sub and top.

Your videos have helped me dial in my personal PA setup. Thanks for the content! This video came out 1 day before I was as playing with some new KV2 VHD speakers I purchased and was playing with so perfect timing. A previous video helped me get all my subwoofers at same gain level and extend my low end performance.

Fantastic video i can’t wait to give this ago

One thing I came here looking for and didn’t find was the OSM gain setting. I had the same mic into my UA Volt interface with the interface gain all the way down and I still had 40 to 50 db of audio. Where could I be going wrong?

Also, I compared to a handheld SPL meter to see how things compared and I had to bring the OPS gain way down for the reference mic to b close to the SPL reader. Any insight on where I’m wrong?

Have you got any links to target curves? Thanks :)

Your Video is great! I would highly appreciate something like driver alignement in a single speaker or just speaker time alignement in general and phase alignement from (lets say) subwoofers to top / kicks. Thumbs up!

Great vid! Is there any drawback when using the builtin (software?) loopback instead of a separate cable doing the loopback e.g. from output 2 to input 2? Or in other words, is there any benefit when using a physical cable connection instead of the software loopback? I would assume much lower latency?

I'm a little lost on how to apply the measurement curve. I work on an M32, so my "theory" is that essentially I would get measurements via OSM, then just make those EQ cuts on my main L/R bus? Or am I now running all of my inputs via the interface I'm using for OSM?

Thank you for your work. You are doing it wonderfully. Your knowledge, calmness, logic, and the positive attitude towards people are clearly noticeable. I would be happy to support your work. Best regards :)

Thank you so much!
I'm russian as a creator of OSM, but i think that he explains his app not so anderstandably as you😄
