Awesome octave graphs, but needs a few additional features

In the office, I have a $10K B&K graphical sound meter. "Octave" makes better graphs and is easier to use, and have a very quick reaction time! Very impressive! Octave is useful for singling out problematic frequencies (when trying to diagnose is a noise problem is airflow, or due to a fan, or a belt, or a motor). The vertical zoom and vertical centering are awesome.

...But its missing some important features. Unfortunately, it cant be used for documenting overall noise levels-- itll only give you noise levels for a particular octave band (or fraction of that octave band), and you cant take snapshots of individual charts.

Here are some needed features:
-Information display needs to give the overall sound level.
-Needs to ndicate if the displayed sound level is A-weighted, Z-weighted, or unweighted.
-Needs to let you choose the weighting, as well as specific time-weighted rate, such as LAeq.
-Needs to let you calibrate the overall levels against a professional sound level meter.

This app would be worth five stars if it had the needed items above!

Features that would be "nice to have":
-Enable you to take snapshots, preferably an image plus CSV file showing the levels of each octave-band.
-Let you enter names or sequence numbers for the image/text snapshots.
-Let you record an audio comment to go along with the snapshot.
-Let you remove the "Peak Note" information if you dont need it.
-Let you record a noise chart for several seconds, dumping the data to a CSV file, and averaging the overall and octave sound levels.

Im looking forward to the next version update!
