RetroPie, PiMusicBox ect. Linux ALSA 432 & 528 Hz Real-Time Tuning Engine

Giantofstone

Hello,

all past generations consoles used A4 440 Hz Audio Pitch Standard which means nothing and is bad for you. Retrorangepi 4 uses ALSA so i configured a Real-Time A4 440 Hz to A4 432 Hz audio output plugin for it and configured that to be used as default to work.

You can also use the C5 528 Hz tuning. Just change the number of semitones to 0.156674, what will change A4 to 444 Hz.


Before your start, in the main menu press start and find desktop. In the desktop find a terminal.

First step is to install ladspa-sdk and tap_plugins

1. sudo apt-get install ladspa-sdk && sudo apt-get install tap-plugins

Copy code

Second step is to edit ~/.asoundrc

1. sudo pluma ~/.asoundrc

Copy code

Here is the example of ~/.asoundrc file for OrangePi PC (H3), just copy and paste.

1. pcm.snd_card {
   
2.         type hw
   
3.         card 1
   
4.         device 0
   
5. }
   
6. 
   
7. ctl.snd_card {
   
8.         type hw
   
9.         card 1
   
10.         device 0
    
11. }
    
12. 
    
13. pcm.dmixer {
    
14.     type dmix
    
15.     ipc_key 1024
    
16.     ipc_perm 0666      
    
17.     slave.pcm snd_card
    
18.     slave {
    
19.         period_time 0
    
20.         period_size 1024
    
21.         buffer_size 4096
    
22.         rate 44100
    
23.         format S32_LE
    
24.         channels 2
    
25.     }
    
26.     bindings {
    
27.         0 0
    
28.         1 1
    
29.     }
    
30. }
    
31. 
    
32. pcm.ladspa {
    
33.     type ladspa
    
34.     slave.pcm "dmixplug";
    
35.     path "/usr/lib/ladspa";
    
36.     plugins [{
    
37.         label tap_pitch
    
38.         input {
    
39.             controls [ -0.317667 0 -90 0 ]
    
40.         }
    
41.     }]
    
42. }
    
43. 
    
44. pcm.dmixplug {
    
45.   type plug
    
46.   slave.pcm "dmixer"
    
47. }
    
48. 
    
49. pcm.!default {
    
50.     type plug
    
51.     slave.pcm "duplex"
    
52. }
    
53. 
    
54. pcm.duplex {
    
55.     type asym
    
56.     playback.pcm "ladspa"
    
57. }
    

Copy code

Done! Save and Restart.
Now you can heal your energy while playing all your favourite games without getting annoyed and play longer.
This will change the frequency to 431.99998843001134 Hz with a pretty sound effect and 440 Hz becomes funny next to it.
There are issues getting analog sound to work but may be a way around that.

For a Raspberry Pi you need to install Raspbian, install ladspa-sdk and tap_plugins, edit /usr/share/alsa/alsa.conf with the code under pcm.hw and manually install RetroPie. To auto start RetroPie you can edit /home/pi/.bashrc and add the line /usr/bin/emulationstation at the end of it.

This also works very good on PiMusicBox.

1. pcm.ladspa {
   
2.     type ladspa
   
3.     slave.pcm "dmixplug";
   
4.     path "/usr/lib/ladspa";
   
5.     plugins [{
   
6.         label tap_pitch
   
7.         input {
   
8.             controls [ -0.317667 0 -90 0 ]
   
9.         }
   
10.     }]
    
11. }
    
12. 
    
13. pcm.dmixplug {
    
14.   type plug
    
15.   slave.pcm "hw"
    
16. }
    
17. 
    
18. pcm.!default {
    
19.     type plug
    
20.     slave.pcm "duplex"
    
21. }
    
22. 
    
23. pcm.duplex {
    
24.     type asym
    
25.     playback.pcm "ladspa"
    
26. }

The full number of semitones still works better and change -90 to -24 or -48 or -72 for PCM System Minimum. With the last 0 to -6 so it filters the sound from ALSA otherwise it will hurt your ears. Also you may optionally install tap-plugins 1.0.0 for Debian Jessie and Stretch from this link Here. With raspberry pi dmixer wasn't working. Try "hw" instead of "dmixer", the OS may be optimized for that.

Should look like this:

1. controls [ -0.3176665327 0 -24 0 ] 432.00000009 Hz

Copy code

Other option is to change the percantage instead of semitones:

1. controls [ 0 -1.81818179772 -24 0 ] 432.00000009 Hz

Copy code

9 is the meaning of Infinity and Enlightenment encoded in all Polygons. -24 Means Vortex and if for example playing audio files of 120db and 96 db of the dynamic range will output audio at 96 db and 72 db of the dynamic range and for health reasons shouldn't be changed. Had to do with 12 digits, it has a lot of meaning called enlightenment.

The safe settings without repeating decimal fraction are following:

444.00000009 Hz = 0.90909093 %

432.00000009 Hz = -1.818181797 %


Decibel Switch Works as this:

0,0
-12,-3
-24,-6
-36,-9
-48,-6
-60,-3
-72,-6
-84,-9
