    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • How to generate an audio file from N concatenated audio samples separated by certain time intervals ?

    25 mars 2020, par Antonio Oliveira

    I have an Android application that simulates a Drum Kit where the user is able to "record" their performances.
    Currently this recording consists of store in a .json file which audio sample was played and the time that it took between the previous and the current note, something like this :

    [
    
    {
    
        drumkit: 'snare',
    
        time: '0'
    
    },
    
    {
    
        drumkit: 'kick',
    
        time: '5'
    
    },
    
    {
    
        drumkit: 'splash',
    
        time: '3'
    
    }
    
    {
    
        drumkit: 'snare',
    
        time: '0'
    
    },
    
    {
    
        drumkit: 'kick',
    
        time: '2'
    
    },
    
    {
    
        drumkit: 'crash',
    
        time: '0'
    
    }
    

    
]

    That said, now I’m looking for a way to generate an audio file (mp3 for example) from that record, since I already have the audio files in the app and also the logical sequence of the recording.

    I tried to follow the approach shown in this question (https://stackoverflow.com/a/656302).
    The merging of audios worked, but in this way the next audio can only be placed after the previous one ends, making it impossible for two (or more) audios to be played at the same time. It is also not possible to define the time that separates the audios.

    The ffmpeg lib seems to be good for dealing with this type of problem, there is even a version for Android.
    But I don’t know how to do this using it.

    Would anyone have a suggestion on how to solve the problem ? (Using or not ffmpeg)
