The IPhone based sound pressure meter that I use, SLA Lite seems to be inconsistent lately. How that can be I don’t know but it is. I doubt it’s the IPhone mic.
Any recommendations out there?
My ears are so finely tuned, that I don’t need a meter…
All kidding aside, I use decibel plus from App Store, seems to work fairly consistent
I use one called Spectrum Analyzer RTA from Onyx Apps. Seems reasonably reliable, and if you have an adapter you can use it with a UMIK-1 mic and its cal file.
Triplett SomiCheck MC, got it on Amazon for thirty bucks. Shows current, peak, or minimum volume.
iPhone app NIOSH SLM.
Edit: attended a Foreigner and Styx concert on Saturday at a big place in Tinley Park, IL. A good time but it feels like NASCAR…peaks up to 125db…I wear ear plugs of-course.
One other thought, they are really just cover bands that own the name, still, very professional and pretty good sound in a lousy sounding place. Vocals were clear. Lots of dads with their boys belting out the lyrics.
I agree NIOSH is the best for pure SPL, but I maybe mistakenly thought Ron was looking for more of an RTA.
For my iPhone I use and am happy with NIOSH SLM. I also, have a handheld RadioShack SLM.
No spectrum analyzer. I just want sound pressure level.
John–it works great. Thanks.
Trusty Radio Shack handheld.
A $30 one from Amazon, and it soon bored me so it’s in the storage bin somewhere.
dB Meter on my iPhone and original Radio Shack SLM (meter not LED)
I often miss Radio Shack.
I also have the meters on the amp, and if using the E 800 pre-amp function (I rarely do as my line stage just sounds better) the volume displays in db

Classy!
I still recall the sweet E800 from a recent dem. A fine piece.

Thank-you for sharing. I suspected it was bass lite when using it to place my REL 5Ti subs.
It may still be available, but Rives Audio had a CD of test tones in two forms - ones set of tones that are “normal”, and another that are meant to be used with the classic RS meter. This set of tones were ‘pre-corrected’ so they’d read correctly on that meter. I’m not sure if the newer versions of that RS meter have the same FR characteristics, but for those who have the older version this CD saves a lot of headache.
For my purposes, volume matching for comparisons, I don’t care about accuracy as much as repeatability. If I get an error, I want it to be consistently the same error.
One must admit having both is nice.
