1. Manual Setup
   1. Download and install dependencies
   2. Setup Microphone
   3. Install Music LED Strip Controller (MLSC)
   4. Add MLSC to the autostart.

Manual Setup

Note: You do not need to do the Manual Setup if you already used the Automatic Setup Script.

Download and install dependencies

1. Update packages:

sudo apt-get update
sudo apt-get upgrade

2. Install Audio Driver

sudo apt-get install libatlas-base-dev portaudio19-dev

2. Install Python

sudo apt-get install python3

3. Install required Python modules:

Install Pip:

sudo apt-get install python3-pip

Upgrade Pip to the newest version:

pip3 install --upgrade pip

Install Numpy (Offers a lot of mathematical functions and matrix manipulation. This version is required because 1.16 has a memory leak when using queues.):

sudo pip3 install -I numpy==1.17.0

Install Cython (Required to build the rpi_ws281x. module):

sudo pip3 install cython

Install Scipy (Offers a gaussian filter.):

sudo pip3 install scipy==1.3.0

Install Flask (The web server component.):

sudo pip3 install flask

Install PyAudio (Offers the audio input stream, which will be processed.):

sudo pip3 install pyaudio

Install coloredlogs:

sudo pip3 install coloredlogs

Install Flask_Login:

sudo pip3 install Flask_Login

Install Jinja2:

sudo pip3 install Jinja2

Install environs:

sudo pip3 install environs

Install waitress:

sudo pip3 install waitress

4. Build and install the rpi_ws281x module.

Select a place where you want to build the module. /share is used by default.

Create a new directory:

sudo mkdir /share

Navigate to the directory:

cd /share

Install Git:

sudo apt-get install git

Install the dependencies for rpi_ws281x module:

sudo apt-get install build-essential python3-dev scons swig

Ensure you are in the /share directory and clone the repository:

sudo git clone https://github.com/jgarff/rpi_ws281x.git

Move inside the cloned repository and build the project:

cd rpi_ws281x
sudo scons

The Terminal output should look like this:

Move inside the python directory and install the python module:

cd python
sudo python3 setup.py install

Setup microphone

Plug-in your USB microphone.

Create/edit /etc/asound.conf using Nano or any other preferred editor:

sudo nano /etc/asound.conf

Write the following text to /etc/asound.conf:

pcm.!default {
    type hw
    card 1
}
ctl.!default {
    type hw
    card 1
}

In Nano, you can save changes by pressing "Ctrl+X", "Y" and "Enter".

Set the USB device to be the default device by editing /usr/share/alsa/alsa.conf:

sudo nano /usr/share/alsa/alsa.conf

Enable the Default Card:

Change

defaults.ctl.card 0
defaults.pcm.card 0

To

defaults.ctl.card 1
defaults.pcm.card 1

Disable unused interfaces:

Change

Reboot:

sudo reboot

Install Music LED Strip Controller (MLSC)

Navigate to the /share directory:

cd /share

Clone the repository:

sudo git clone https://github.com/TobKra96/music_led_strip_control.git

Add MLSC to the autostart.

Using a systemd service, each time Raspberry Pi reboots, MLSC will run.

Stop MLSC if it is still running.

1. Create a file mlsc.service in /etc/systemd/system/:

sudo touch /etc/systemd/system/mlsc.service

2. Add the following to the created mlsc.service file:

[Unit]
Description=Music LED Strip Control
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/share/music_led_strip_control/server
ExecStart=python3 main.py
Restart=on-abnormal
RestartSec=10
KillMode=control-group

[Install]
WantedBy=multi-user.target

3. Run the following commands to enable and start MLSC:

sudo systemctl daemon-reload

sudo systemctl enable mlsc.service

sudo systemctl start mlsc.service

4. Reboot:

sudo reboot

5. Check if the service is running:

sudo systemctl status mlsc.service

MLSC should now restart on reboot.

To remove the service from autostart, run the following commands:

sudo systemctl stop mlsc.service

sudo systemctl disable mlsc.service

Note: The WorkingDirectory specified in the service is /share. If you did not change anything during the installation, the service should work without issues.
