  • How to detect the silence at the end of an audio file ?

    1er mars 2017, par Ali Akber

    I am trying to detect silence at the end of an audio file.
    I have made some progress with ffmpeg library. Here I used silencedetect to list all the silences in an audio file.

    ffmpeg -i audio.wav -af silencedetect=n=-50dB:d=0.5 -f null - 2> /home/aliakber/log.txt

    Here is the output of the command :

    —With silence at the front and end of the audio file—

    [silencedetect @ 0x1043060] silence_start: 0.484979
    [silencedetect @ 0x1043060] silence_end: 1.36898 | silence_duration: 0.884
    [silencedetect @ 0x1043060] silence_start: 2.57298
    [silencedetect @ 0x1043060] silence_end: 3.48098 | silence_duration: 0.908
    [silencedetect @ 0x1043060] silence_start: 4.75698
    size=N/A time=00:00:05.56 bitrate=N/A

    —Without silence at the front and end of the audio file—

    [silencedetect @ 0x106fd60] silence_start: 0.353333
    [silencedetect @ 0x106fd60] silence_end: 1.25867 | silence_duration: 0.905333
    [silencedetect @ 0x106fd60] silence_start: 2.46533
    [silencedetect @ 0x106fd60] silence_end: 3.37067 | silence_duration: 0.905333
    size=N/A time=00:00:04.61 bitrate=N/A

    But I want something more flexible so that I can manipulate the output and do further task depending on the result.
    I want to get the output something like true or false. If there is a certain period of silence exists at the end of the audio file it will return true and false otherwise.

    Can someone suggest me an easy way to achieve this ?

  • lavf : Use av_gettime_relative()

    6 mai 2014, par Olivier Langlois
    lavf : Use av_gettime_relative()
    

    Whenever av_gettime() is used to measure relative period of time,
    av_gettime_relative() is prefered as it guarantee monotonic time
    on supported platforms.
