Adding the FFmpeg Library by clicking the locate button Choose the No option for manually adding the library. Click on the Locate button in front of the FFmpeg Library and it will automatically find the installed FFmpeg library for Audacity. Can I instruct ffmpeg what the duration is when it is doing the splitting? And can I change all the amplitudes to match the audacity file? I'm not sure what to do to get to the 80% accuracy rate, but increasing volume seems to be the most promising solution so far.Īny help would be greatly appreciated. Opening the Preferences in Audacity Select Libraries in the list on the left side. One thing that stands out to me is that the duration isn't the same. Split with Audacity: (80-90% accuracy) Samples read: 1689984 Here are the sox -n stat results for each file: I guess what I'm trying to ask is, what does Audacity do differently? I found that when I increase the volume of the output files, the accuracy gets better, but never as good as when I did the splitting with Audacity. For what it's worth, the audio files sound identical to the human ear. I've been experimenting for about a week now but I can't get the accuracy up. However, once I tried to automate the splitting using ffmpeg (more specifically: ffmpeg -i input_filename.mp3 -map_channel 0.0.0 left.wav -map_channel 0.0.1 right.wav), the accuracy dropped drastically. The accuracy was about 80-90%, which was perfect for my purposes. So during testing, I manually split the original mp3 file into two WAV files (one for each channel, converted to mono). The mp3s I receive have one voice playing in the left speaker, the other voice in the right speaker. So I'm working on a speech to text project using Python and Google Cloud Services (for phone calls).
