The Audio Quality Tester is a Python tool with GUI that let's you compare lossy MP3 formats. The aim is to find out at what point a person is no longer able to differentiate the file formats. Currently suppoerted input file formats are MP3 and WAV.
Download the release file and pip-install it or build it from source. You need to install ffmpeg.
FFMPEG
- macOS: brew install ffmpeg
- Ubuntu/Debian: sudo apt-get install ffmpeg
- Windows: Download FFmpeg from ffmpeg.org and add it to the system PATH.
Launch the main function to start the program:
import audioQualityTester
audioQualityTester.main()
The tool will start a GUI which consists out of three screens.
In the start screen you input the path to your audio file. It must be a MP3 with 320kbps or a WAV file. If you tick the play audio only once box you won't be able to hear an audio format twice. Then select exactly five audio file formats you want to compare with each other. Then hit start! The processing of the files can take a few seconds.
In this screen you can play your choosen file formats and choose the one you think is correct. You can adjust the slider on the top to start the audio at a specific point.
In this screen the result from your classification is presented. For each audio file you will see the metadata and the two spectrograms.
On the bottom you are able to go back, save all the created data into a directory, restart the test and exit the program.
- assert interoperability
- start debug mode by setting a flag
- add loading bars for start & listening screen
- add proper testing suite
- better log file handling!
