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.
I'm so glad it's helpful. I know exactly what you mean, It's hard know where to start with this stuff, but it's so useful to have a working knowledge of this stuff no matter what you're doing in the sound world. Keep at it!
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.
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
Ooo!! I had no idea this software existed - FAB! Thanks, and the tutorial was great, lots of detail and none of the waffle and repetitions so beloved of so many people on UA-cam. So, now I'll be looking at a bargain interface and measurement mic - though for delay calcs I may use a cardi SDC.
Dear Sir, first of all I hope you are well. I am a student and I have been following you since I first saw you on UA-cam. I want to thank you very much for your great contribution to learning for people like me. I also want to tell you that I love the way you transmit information, you do it in a simple, clear and at the same time effective way, it is impossible not to understand you. Regarding Open Sound Meter, I am very interested in learning how to use it, but there is little information and you are contributing with very valuable information. I would like to know if it is possible to calibrate a microphone in Open Sound Meter. Thank you very much for everything. May God bless you.
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!

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.
Estimado Señor, antes de nada espero que usted esté bien. Soy estudiante y le sigo desde que le vi a usted por primera ves en UA-cam. Quiero agradecerle enormemente su gran aportación para el aprendizaje a personas como yo. También quiero decirle que me encanta como trasmite la información usted lo hace de manera sencilla y clara y a la ves eficaz es imposible no entenderle a usted. Con respecto a Open Sound Meter yo estoy muy interesado en aprender a utilizarlo pero hay poca información y usted está contribuyendo con información muy valiosa. Me gustaría saber si es posible calibrar un micrófono en Open Sound Meter. Muchas gracias por todo. Que Dios le bendiga. 😘😘😘😘
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?
Good question. Using the loopback functionality introduces a degree of latency so you get long delay times when compensating. I can't remember exactly where you can read more about it. Might have been the smaart manual.
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?
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?
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.
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?
Great idea. I'll have to make a video about SPL measurement using osm. To measure SPL you need an external calibrator like this: www.isemcon.net/ashop/product_info.php?products_id=3 You should calibrate the mic and preamp in osm every time use it. I'm not exactly sure how that's done in osm but I'll find out and make a video
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.

great . i was just talking about this today. its like you always know what i need haha
Glad I could help! Someone asked me about it the other day and I thought why not :)

Fantastic video i can’t wait to give this ago
Tnx for video 💞 Please make more videos for Open sound meter.

Much love and great respect ❤❤
Thanks alot
My pleasure 😊
Thanks very much great guide!
Glad you enjoyed it!

Yeah it can be tricky at first. Definitely took me a few tries to get used to it and build a workflow that suited me.

OSM is going to be the first software I’m going to install on the new iMac that comes tomorrow- before Tidal!
Haha nice!
one of your videos in this series will include using the Sub Align tool, I hope!
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!
Sounds like the units might me microseconds
Good question. Using the loopback functionality introduces a degree of latency so you get long delay times when compensating. I can't remember exactly where you can read more about it. Might have been the smaart manual.
Have you got any links to target curves? Thanks :)

lol 300ms is like 100 metres
