432Hz Op Amp Emulation

Giantofstone

How do i have 432Hz amp in every sound that comes out of my orange pi. I never listen to 440Hz sound.

i don't know how to do that, but some daws can transform the frequencies what you want. i use studio one 2 to do that

I have managed to find a solution for this issue with Ubuntu 16.04.2 using ladspa pitch shifter plugin and patching pulseaudio output with it so every sound that comes out gets changed from 440Hz to 432hz.

Step 1
Download and install ladspa-sdk

1. sudo apt-get install ladspa-sdk

Copy code

Step 2
Download and install tap-plugins

1. sudo apt-get install tap-plugins

Copy code

Step 3
Find out your audio output sink name

1. pacmd list-sinks | grep -e 'name:' -e 'index'

Copy code

Step 4
Configure ladspa pitch shifter plugin to work with pulseaudio

1. pacmd load-module module-ladspa-sink sink_name=ladspa_out master=alsa_output.pci-0000_00_1b.0.analog-stereo plugin=tap_pitch label=tap_pitch control=-0.3176665363342977,0,-90,0

Copy code

Change master to your own output device found in step 3. -0.3176665363342977 is the precise semitone change from 440Hz to 432Hz.

Step 5
Now select your brand new audio output device in pulseaudio settings.

After everything is done you can play everything that uses the standard 440Hz pitch at the natural 432Hz frequency, you can even use it as sound converter from 440Hz to 432Hz for any input.

To unload sink:

1. pacmd list-modules

Copy code

1. pacmd unload-module <#>

Copy code
