How to set “frequence”,“q”,“gain” and other curve functions

[Kvas392]

Hi,I'm a new one for python, I want to know how to set the frequence curve functions by code, can you give examples? Thanks.

[schwinn]

Hi,

below is an example.

These are the possible values for "type".
PARAMETRIC
LOSHELF
HISHELF
LOWPASS
HIGHPASS
BANDPASS
NOTCH
ALLPASS
HI6DB
LO6DB
INVERSION

The MA 1 software is using only using filter type "PARAMETRIC".

Hope this helps.

./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"enabled":[true,true,true,true,true,true,true,true,true,true]}}}}'
./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"type":["PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC","PARAMETRIC"]}}}}'
./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"frequency":[84.889,98.930,111.507,196.987,73.046,1291.415,135.585,55.138,381.993,583.255]}}}}'
./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"q":[8.741,11.543,15.390,4.006,8.175,3.553,9.344,3.533,4.248,4.989]}}}}'
./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"gain":[0.000,0.000,0.000,0.000,0.000,0.000,0.000,0.000,0.000,0.000]}}}}'
./khtool.py -i en1 -t 1 --expert '{"audio":{"out":{"equalizer":{"boost":[-3.589,-3.793,-3.041,-8.611,3.186,-2.802,-6.297,1.915,1.443,-1.265]}}}}'

Thanks
Can you try it in KH80dsp? (PEQ function)

[schwinn]

This will work for KH80 DSP.

[Kvas392]

Hi I try it but not work.My system is windows11, First I use Powershell to research my interface name.Then use Miniconda3 try to get my KH80dsp information, can you help me to find where is wrong? Follow is my code,thanks.

I have never tested it on Windows. I will test it in the next few days and get back to you.

[Kvas392]

Thanks,I connect right speaker to my PC with actual net line, I also try it with CMD, Now I can generate khtool.json, json's information is right ,but order(-q) don't work.

[schwinn]

If you have two sepakers connected, please use this command, until both speakers are discovered.

D:\khtool-main>python .\khtool.py -i Ethernet6 --scan

The you can use this command the query all speakers.

D:\khtool-main>python .\khtool.py -i Ethernet6 -q

[Kvas392]

Hi, I try it and find my two speakers, but it show the Errno 11001 ,I will search further on Google, and wait for your test, Thanks.

[schwinn]

I have uploaded a new version. Please give it a try. Under windows, the inteface no longer needs to be specified.

[Kvas392]

Best wishes for a happy New Year!
I test it in win11, but I find some issue in it:

1. the equalizer can't show all parameters(like q gain and other frequency... );
   
2. the expert mode seem not work;

Brightness/Mute/Unmute/Save is work.

[schwinn]

Hi,

I have reverted the last change in khtool. The interface must now specified again. On my Windows 11 system, I did a ipconfig /all and the local link IPv6 address of the adapter was like 'fe80::3000:0000:0000:cd4f%35'. Then the interface name is the name after the percent sign, so it's 35 in this case.

On windows, the quotation marks has to be excaped. So the correct expert mode command looks like this:

python khtool.py -i 35 --expert {\"m\":{\"audio\":null}} -t 0

The problem with the incomplete output is related to the pyssc library. Please use the my fork of the library. Here are the commands to replace the version.

pip3 uninstall pyssc
pip3 install https://github.com/schwinn/pyssc/archive/master.zip#egg=pyssc

[Kvas392]

Hi
It not ok
Step1:
Update pyssc，then I connect my Right speaker to motherboard with line, I can find it in MA1 sofaware


I also try Left speaker, It work.

Step2:
I research 以太网6 Idx with CMD, the Idx is 4

Step3:
I exit MA1 software, and try khtool.py but not work.

Step4:
I check 以太网6 IPv6，not find problem


PS:
I connect pair speakers to my H3C BX54 Router LAN ,and try to find them on WIFI with MA1 software, I can't see anyone, I will try to check my setting ,strangeness......

[Kvas392]

I restart my PC, Open MA1 Software, I can find pair speakers use WIFI(WLAN2), then try khtool.py it also not find my speakers.

[schwinn]

This is strange, because the interface configuration is not used for the device scanning. I have uploaded a new version, where the scanning timeout is increased. Please power cycle your speakers before the scan and try the new version.

[schwinn]

Please post the output of pip3 show pyssc
