v0.1 Alpha

Setup

This is an 8 Track audio player written in Python for the HifiBerry DAC8. I don't write Python often, so this is not very good and it barely works.

You will need to setup a virtual environment to run the code. You can do this by running the following commands:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Audio Files

Create a directory to place the tracks you want to play. In this example we will use the directory tracks. You can use any folder you wqnt. You can use the following command:

mkdir tracks

Place your multi-track audio files in the directory you created in the previous step. Place each song in a separate folder. The code will play the songs/tracks in the order they are listed in the directory. If more than 8 tracks are present, the code will only play the first 8 tracks.

tracks
├── 01_Dangerous_Match_One
│   └── 01_drums.wav
│   └── 02_bass.wav
│   └── 03_gtar.wav
│   └── 04_gtar2.wav
│   └── 05_keys.wav
│   └── 06_horns.wav
│   └── 07_vox.wav
│   └── 08_vox2.wav
├── track2
│   └── track1.wav
│   └── track2.wav
│   └── track3.wav
│   ...

Roll it

To run the code, you can use the following command. Replace ./tracks with the directory you created in the previous step. Audio files are automatically converted to 16-bit 44.1kHz WAV files. This may take some time depending on how many tracks you have.

sudo ./venv/bin/python3 ./player.py ./tracks

The code will start playing the tracks in the directory tracks. You can stop the code by pressing Ctrl+C.

Controls:
Space: Play/Pause
N: Next track
P: Previous track

Clearing Temp Audio Files

The code will create temporary audio files in the /tmp directory. These files are not deleted when the code is stopped. You can delete these files by running the following command:

sudo ./venv/bin/python3 ./clear_files.py

Issues

Sometimes existing temp files cause clicks and pops in the audio playback. I have no idea why. I usually just clear ahd temp files and restart the code.

Goals

This really should be written in Rust, but I'm not smart enough to do it.
