I usually have 2 or more files to split from the same recording and I wanted to be able to split them into the same folder without risk of overwriting any of the files. The first input needed is the filename you want to split, and after that you specify the file name prefix of the output. It needs you to enter two variables to run, which are noted in the script by $1, and $2.
You run the command by calling the script, which I called ‘Split’. It’s quite long though, so I created the command as a bash script on Centos 8. We now have the raw information we need to build our ffmpeg command. The sample rate, 44.1k (We run our X32 at the 44.1k sample rate, for easier playback from USB thumbdrives, but you may have yours setup for 48k.). The important details are the name of the stream, #0.0. I first started with the ffprobe command to give me the details of the file.įor my use, it was really only the very last line of it’s output I needed to see: I lost invested 5 or 6 hours this past weekend to try again and finally had some more success. I knew it was possible, but I hadn’t been able to get it working the way I wanted. I had tried to do this once before with ffmpeg. The first step was to use a tool to break the 32 channel file into 32 separate files. For just the music from a two service Sunday I was looking at around 30GB of data. Its tedious, and I would often get behind in the clean up, which means I was using up a lot of storage.

It creates one channel as though the file were a really massive surround sound mix.įor a while I was opening the files in (the excellent, free and open source audio editor) Audacity, removing the silent ones by hand and then exporting out just the tracks I need.

Your DAW, like Pro Tools, Reaper, Cubase, etc., will easily open the files the X-Live creates, but there is no clean way to import this one multi-track file as 32 channels in your DAW. When it comes time to work with the files though, you have to do some cleanup before you can really get started. There is not gap, pop, or pause between the two files. When the file hits the 4GB limit of the SD Card’s filesystem, the X-Live closes that file, and opens a new one seamlessly. From a SD Card bandwidth standpoint, it’s much easier to write one big file than it is to write 32 separate files.
This works great, but it doesn’t record 32 individual files It records all 32 channels into one multi-channel file that are a bit over 12 minutes in length. For the mix of channels we need, I tell the X-Live to just capture all 32 channels. For instance, you can record 8/16/32 channels off the board but you can’t really pick which ones. The X-Live card works great, but it does lack some flexibility we’d like. This has saved a lot of recording overhead, since we don’t need a PC, display, etc., but it’s also created some hassles. *** Work on this continues over on GitHub: ***Īt my church we use a Behringer X32 mixer to run Sunday services and we added an X-Live card, instead of the included USB Audio interface card, so we can record our services, multi-tracked, direct to an SD card.
