Hi.
I’ve always wondered if the VST or the DAW is the limiting factor why I could not attain a higher frequency than 22050 kHz.
It appears the DAW is the limiting factor…
I may design an ultrasonic equaliser and execute a stand-alone device to confirm it will actually work without any oscillation when I have more time.
Cheers!

The VST spec specifies sampleRate as double with units of Hertz - I'm not aware of any limitations placed on the setting of this. The DAW can limit the sample rate, but the other limitation is your audio interface - some have a maximum of either 44.1 or 48 kHz.

Hi Dell 🙂
How did you get VST Plugin Analyzer to measure that high?
I only get it up to 22050 Hz...
Do you have the pro/ payed version?
BTW I think going beyond 22050 kHz is impossible in todays aigital audio systems limited 96 kHz in 192 kHz samplerate.
😈 22050000Hz 😉
Ha ha I just had to mention it. I have NEVER done the same punch error 😇

Hi.
It appears the limitation is not the DAW but the playback file.
Reaper appears to be locked (by default) to 44100 however, you can change the playback settings of the sample rate.
Samplitude & Wavelab will automatically switch its sample rate based on the playback file. I haven't tried any of the Demonstration DAWs (Cubase, FL Studio, Cakewalk, Adobe Audtion, etc) at the moment.
I’m using a home computer (Dell) with the stock soundcard. I would imagine any computer that offers a playback rate of 96 kHz would have no problem.
I’m more than certain Synthmaker can disengage anything beyond 22,050 kHz at 44.1 kHz, and extend the bandwidth beyond 22,050 kHz when the sample rate is higher than 48 kHz. Anyone knows which module will do this?
The video below demonstrates a boost at 40,000 kHz using pink noise sampled at 88.2 kHz

Tor,
I take it you never worked on Windows 98 😉
You can increase the upper frequency response using VST Analyser’s ini file.
Bear in mind I don’t work in a digital mindset. My thought patterns follow an analogue concept. It was only a matter of time before I would venture beyond 20,000 kHz since I always knew such a limitation was unacceptable for high-resolution audio.
There is definitely information beyond 20,000 kHz 😀
This video demonstrates how frequencies beyond 20,000 kHz can compliment the sound

Right!
I've extended the frequency response over 40 kHz. I also figured out a way to have everything beyond 20,050 kHz become active only on audio files that offers a sample rate no lower than 88.2 kHz.
This is the frequency response from 21,000 kHz - 42,000 kHz. There are still more testing underway. 🙂
Cheers!
