Hi M2Circuits, thanks for the feedback.
There’s always a tradeoff in the plugins in terms of how many options can be shown. There’s an attempt to striking a balance between what is most needed in the plugins and complexity. If every plugin surfaced every option, then it’s a long, long list of options that would be a bit daunting to most. Sometimes I think it’s better just to add another plug-in rather than adding too many options to a single plug-in.
With averaging, remember that FFT size will also average imperfections. A 256K FFT should be pretty similar to averaging 32 8K FFT (32*8).
The 2.0 release of the software will do better with units, but the plugins will very much still want to speak in dBV and the offset method previously outlined will need to suffice for the near and mid-term.
Below is a link that might help speed up frequency response measurements on a tape player. You’d basically create a WAV of a special chirp, then record that using your best “reference” deck, and then play the special chirp back on the deck you are testing and you should get the overall frequency response of the reference deck (used to record) and the DUT (used to playback). Of course, if you are already using a test tape with reference tones, it’s tough to beat the certainty there. But there could be a good time savings for intermediate checks. You could do a full freq response chirp in a few seconds. And also save wear and tear on your reference tape until the final test was needed.
