The analyzers show 20 to 20,000hz, which is great but the range above and below is important to know about in case there are any issues. There are some spikes in a file I have that are above 20khz but it's invisible in the Melda analyzers.
People commonly used 96khz and above samplerates so this is not unusual. Also there are other applications for low frequencies (e.g. haptics signals on next generation game controllers) that make this useful.
Ideally a low and high control would be added that would scale the display.
If not, I'll have to use a 3rd party analyzer which is a shame as the Melda ones are great.

Analyzers need to display higher and lower frequencies

Sorry, won't happen. The engine is optimized for this range and changing it would effectively mean rewriting the entire analyzer and if you look at how much is there, well, not going to happen sorry.

Honest question: why not use filters to remove what might be lurking there? Is that sonic information important to the end result?

Okay, thanks vojtech. Just know if you ever see an opportunity to tweak it that there is demand for higher resolution.
As for what do you need it for and why not just use filters... I work in game audio, not music. We operate at 48hkz as an output format, so there is material present above 20khz. All non music media operates at multiples of 48khz. It's a complicated subject, but an easy example of why we don't filter assets above 20khz is because we apply pitch variations to sounds, if you filter sounds at 20khz then you'll hear a hole in the high freqs when pitching down at runtime.
In the above case, there was a report of an issue above 20khz and I simply can't see it in Melda analyzers. While the ear can't really hear above 20khz, that doesn't stop the information being there and messing with things like dynamics processing etc, so we need to be able to know what's going on.

I'm curious. What frequency range does SPAN (the free one or SPAN plus?) cover? All the pics that I've seen show 20 Hz to 20 KHz.
And, what range do you guys need?

Agree. If you capture a vinyl in 192k or if you're capturing ultra sonics for whatever reason you need a broader range. But this goes for pretty much every eq with built in analyser and any separate analyser. At least capture 0-60khz
BTW this has nothing to do with melda production so why post it here

What does that have to do with anything? You don't think people want to be able to see hyper sonics just because we can't hear them?Hexspa wrote: Sun Feb 14, 2021 7:33 am Honest question: why not use filters to remove what might be lurking there?

Tell me, what happens if we pitch shift a 40k signal down by 3x? That's right, you can hear it now. So we are just supposed to ignore any mega sonic material just because we can't hear it? Damn, I hope no dsper ever listens to you

It goes to 96k and has a red line at the current Nyquist. I would just like it match the current sample rate.DarkStar wrote: Wed Aug 03, 2022 12:15 pm I'm curious. What frequency range does SPAN (the free one or SPAN plus?) cover? All the pics that I've seen show 20 Hz to 20 KHz.

Peace, peace. I don't think Hexspa was implying anything, he just wanted to know. I'm pretty sure that when he says "honest question," that's what he means. "Honest," not snarky or condescending. But I definitely get that default mode of internet discourse is "snark."astralprojection wrote: Wed Aug 03, 2022 12:43 pm What does that have to do with anything?

This information from people who do things other than music is interesting, because, as a musician, I don't automatically understand the requirements that other fields have. It's good to have the extra info, even if it doesn't apply to me at this time.
Now I know that if a friend (or even I) wants to get into game audio, and they want to scope out above-20K information, I'll steer them to Voxengo for a freeware analyzer.
