[Bug]: mini-eq can only work on the 48000Hz

[emofalling]

Before opening

• I searched existing issues for a similar report.
• This is not a security vulnerability.

Affected area

PipeWire routing or default output following

Mini EQ version

0.8.7

Install method

pipx

Linux distribution and version

Gentoo Linux x86_64 Kernel 7.2.3-gentoo

Desktop/session

KDE Wayland

PipeWire and WirePlumber versions

1.6.8 0.5.15

Steps to reproduce

1. Set your sound card's sample rate to 192000Hz
2. Open mini-eq
3. Open System-wide EQ
4. Play your music or a test voice
5. Change the band
6. Then you'll realize that the EQ was actually set to the wrong frequency!

Expected behavior

No matter the sound card's frequency, the EQ should always be adjusted accurately.

Actual behavior

The EQ overall shifted the wrong frequency, and the frequency curve capturer also got generally misaligned.
When the sound card's sampling rate is at 48000 Hz, this problem doesn't exist.
