- true peak measurement based on ITU 1770
- ITU1170/A/B/C/M-weighting filter
- continuous/synced measurement
- record metering results as automation data
- large and accurate live meters
- adjustable pre-gain
- manual loudness/peak/TP match with given reference level
- loudness offset mode
System Requirements:

ah ok.. I see dpMeterII has new parameters too.. so my scripts should still be using v1.4.4. It's good that you can install dpMeterII and dpMeter at the same time.
By the way I sent you an email to the email in your site/support page, but I've received an automatic response error that email could not be delivered or something like that.

Well, i wanted to add some features, but not break your development. So that's why dpMeter II.
Keep up your incredible work:-)

Is this a valid test? I've dropped all the 0.1s.
I put dpMeter on an empty track, enabled record and record monitor and let it do it's stuff.
Later...
RMSi -98.0db
RMSm -98.0db
RMSmm -98.0db
Peak -88.0db
Tpeak -88.0db
Is (-98db -> 0db) the DR or S/n ratio? Does this mean my soundcard effectively only allows 16bit (6x16 = 96) recording and mixing? And my levels are still way too high?

Well, this is the S/N of your sound card: noise is at -98dBFS.
We can measure -90dBFS with Creative SB, open input, fairly cheap sound card:-)
This has nothing to do with digital SNR. Reaper and most of the plugins work internally with 64Bit, so DSNR is at least -385dBFS, just see here: https://en.wikipedia.org/wiki/Audio_bit_depth.
dpMeter 2 min display level is -144dBFS (24Bit), but works internally with 64Bit.

Thanks TB. I have to admit Metering still has me a bit baffled.

Would it be possible to add an LEQ(m) mode to this loudness meter using the specifications outlined in this document?
The LEQ(m) meter is used in mixing for cinema almost exclusively. It is a somewhat niche usage but it is work you really can't do without it. My current meter choice has been flaking out a bit on me so something like this would be excellent, particularly if it could be paired with the Heda Loudness script.
I've been playing around with trying to construct a hack using the rms measurement in the current DPMeter and although I'm getting almost spot on tone measurements with my reafir filters I cannot get something about the time integration and/or summing right.

98 db difference means being able to hear someone else breathe (~40 dbSPL) while standing next to a running jet engine(~140 dbSPL).
You'll be fine.

- Ref Level extended to +/-120dB
- Preset TASA Leq(M) added

V1.2 adds Leq(M) weighting filter and TASA preset.
Please let me know if it works for you, thanks.

Over 2 compared measurements with the Nugen VisLM2 the DPMeter measured slightly quieter on each occasion (.7 dB on one and .4 dB on the other). If someone could compare against the waves WLM we could see if this is within the acceptable margin for error.

So I did a bit more digging. The surround channels are measuring -3dB on the VisLM meter compared to the DPMeter. This is a theatre audio thing where they are attempting to compensate for the phenomena that humans are approximately 3dB more sensitive to sounds from behind.
It also appears the VisLM meter integrates over 3 seconds as opposed to the DPMeter 400 ms. Also the VisLM meter gradually rises to that integration value whereas the DPMeter waits and then jumps to it's first value after 3 seconds. This is probably not important but I mention it just to be thorough.
With these two adjustments made the movement of the meters seems to correlate very well but the DPMeter still reads approximately -0.7 to -0.8 dB LEQ(m).
In short, lower the volume -3dB in the RS and Ls channels respectively, increase RMS window to 3000 MS and raise the gain either 0.7 or 0.8 and the DPMeter (as far as I can tell) will be within .0 dB LEQ(m) of the VisLM meter.
That 0.8 dB gain setting certainly wouldn't inspire confidence but it works. I'm hoping you will see some tweak in the algorithm that could explain the difference.

Update to 1.2.1:
- RMS Mode: M-Weighting Filter adjusted
- RMS Mode: Momentary RMS immediately available
- RMS Mode: LEQ(M) attenuates channel 4+5 by 3dB
- Preset TASA Leq(M) RMS window size changed to 3000ms

Thank you for your extensive testing and feedback. V1.2.1 should adress most of your points.

TASA preset adjusted to 3000ms ML integration time. In any case you can choose any integration time you need by changing RMS Windows size.

We fixed LEQ(m) filter so it is within spec. It could still be that there are small differences to other meters...
Let us know if it works now for you, thank you.

Thank you very much for making this happen. I'll need to do some more testing but I am very impressed with how quickly you could get this out.
You are probably right about variance between meters. In the world of theatrical audio the standards and ones compliance to them often depends upon how close the implementer is corporately to ie. dolby.
Fortunately for us there is usually a +- 1 or 2 to cover those variances.

Many thanks for making this!!
I love the tool, and could not live without, now that I target -12LUFS.
Very easy to use, and nice simple interface. Love it!

Thank you TBProAudio. I'll test it later. Interested about the reset button. Do you think we can trigger the reset button from reascript? If it has a parameter maybe we can change the parameter to trigger a reset command? Because right now to reset from reascript I was reloading again the preset. But that creates an undo point. All I'm trying is a way to reset dpmeter from reascript without generating an undo entry.
Good job on the new GUI

Heda, thank you for your nice words.
For the moment it is not possible to trigger from outside, but i will contact you for a test version.
Lets see if we could find a solution...
