  • convert G.723.1 to normal wav and split channels ?

    10 août 2019, par user9316498

    I have a wav file who’s info is

    ion@aurora:~/Inbound$ mediainfo 48401-3405-48403--18042018170000.wav

    and the audacity shows like this
    enter image description here

    To tackle it I tried

    ffmpeg -i 48401-3405-48403--18042018170000.wav  -f wav test.wav

    But it just appends the second channel at the back of first channel , So I get only single channel.
    and its media info is :
    ion@aurora : /Inbound$ mediainfo test.wav

    Any idea how to solve this ?

    PS : When I hear the original wav file, It feels like the talking is too fast.

    This is how the media info of processed file should look like.

  • Shazaam-esque music comparison [closed]

    17 janvier 2021, par Matthew Trip

    I have two files, a Full.mp4 and a Cut.mp4 I do not care about the video. I want to check if Cut appears in Full at any point. I have tried comparing the streams and their byte arrays but Rider keeps showing memory issues without an explanation. What is the general approach I should take ?
