  • ffmpeg/sox audio processing : Merging files with envelope changes

    2 octobre 2020, par March Hare

    So I have two audio files. One is a music bed with an intro that segues into a looping music clip (let's call this *1). The second is the voice over audio track (referenced as *2, length n).

    


    Audio *1 is fixed, while the voice over (*2) is downloaded about 3 times a day, and can vary in length. *1 is longer than we ever expect *2 to be.

    


    What I need to do is

    


      

    1. Alter the overall gain of *1 to -7.5 dB

      2. 


    2. Begin merging VO *2 at time m, while reducing the volume envelope of *1 by -11 dB. This is fixed based on the length of the intro.

      3. 


    3. Fade everything out to -∞ dB around the end of *2

      4. 


    4. Trim off the silence at the end.
For reference, the total length of the final track should be m+n.

      5. 


    


    Unfortunately, I'm not versed enough with ffmpeg or sox to know exactly what I'm after here, and a lot of the examples tend to do one thing or another and aren't always clear when combining happens. I didn't get a lot of prior notice about this coming down the pipeline, so I'd like to get something relatively quick. We're able to do all of this stuff nicely in Adobe Audition (and I can do something similar in Audacity), but the idea is to automate it. For our envelope adjustments, we were just using linear ramps rather than smoothsteps, and that sounded fine.

    


    The TLDR : The VO track *2 governs how long the file winds up being, while audio bed *1 needs to be ducked when *2 begins, and the whole thing faded out right when *2 ends.

    


    We also have an automation system (radio station automation, specialized for something different than I need), so in a pinch if we have to just cut off the audio at the end of *2, we can get the fadeout from the radio automation system.

    


    I've been using the information at this link to some effect (specifically the bit about ffmpeg volumes), but it still isn't dynamic enough for the situation.
Envelope pattern in SoX (Sound eXchange) or ffmpeg

    


    Anyone have any advice on this one ? I've got Sox and ffmpeg available, and if need be I can probably install other tools as well.

    


  • How can I use FFMPEG in my discord bot thats on github

    21 septembre 2019, par Waldre

    I moved my discord bot to GitHub and Heroku today, everything works fine but I get this error that causes the bot to stop working

    I have already tried adding FFmpeg as a submodule by doing this :

    git submodule add git://source.ffmpeg.org/ffmpeg FFmpeg but it still doesn't work

    These are the errors I’m getting

  • Own music discord bot : FFmpeg/avconv not found. Can someone help me ?

    23 mai 2020, par CreepyGamerCat

    I guess the code is right because the bot finds a song and also joins a voice channel, but it can't play songs, because of this error. The ffmpeg.exe, ffmplay.exe, ffm.probe.exe and YouTube-dl.exe files are in the same folder. (directory : desktop>Discord Bot>node_modules>bin.) Maybe this is a wrong folder, I forgot a important file or whatever. I hope you can help. I use Visual Studio Code in JavaScript.
