  • How to accurately detect the start of the main beat and soundtracks in diverse audio tracks ?

    18 juin 2024, par SnoofFloof

    I'm working on a project where I need to edit soundtracks. The challenge is to detect when the main beat and melody of any given soundtrack is properly developed. I am certain there is better terminology to describe what I am aiming for, but ideally, I want to skip the "build-up" and immediately have the song starting at the "main part". This needs to work for various songs across different genres, which often have different structures and onset patterns, making it difficult to streamline the process.

    


    For example :

    


    https://www.youtube.com/watch?v=P77CNtHrnmI -> I would want to my code to identify the onset at 0:24

    


    https://www.youtube.com/watch?v=OOsPCR8SyRo -> Onset detection at 0:12

    


    https://www.youtube.com/watch?v=XKiZBlelIzc -> Onset detection at 0:19

    


    I've tried using librosa to analyze the onset strength and detect beats, but the current implementation either detects the very beginning of the song or fails to consistently identify when the beat is fully developed.

    


    This was my approach ;

    


    def analyze_and_edit_audio(input_file, output_file):
    y, sr = librosa.load(input_file)
    tempo, beat_frames = librosa.beat.beat_track(y=y, sr=sr)
    beat_times = librosa.frames_to_time(beat_frames, sr=sr)
    main_beat_start = beat_times[0]


    


    I have very little experience with librosa/audio editing, so I would appreciate any suggestions you might have !

  • avcodec/vvcdec : move frame tab memset from the main thread to worker threads

    avcodec/vvcdec : move frame tab memset from the main thread to worker threads

    memset tables in the main thread can become a bottleneck for the decoder.
    
For example, if it takes 1% of the processing time for one core, the maximum achievable FPS will be 100.
    
Move the memeset to worker threads will fix the issue.
