We are a Swiss Army knife for your files
Transloadit is a service for companies with developers. We handle their file uploads and media processing. This means that they can save on development time and the heavy machinery that is required to handle big volumes in an automated way.
We pioneered with this concept in 2009 and have made our customers happy ever since. We are still actively improving our service in 2019, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.
Downmix multiple audio channels into one
Transloadit can downmix an audio file with multiple audio channels. Let's say you have a lossless Apple ProRes file that has up to 12 separate audio channels that need to be merged.
If we wanted to create a 5.1 file, down from 12 (or any number of) audio channels in a file - it would be hard to determine which is left-front, right-front, center, left-rear, right-rear, and bass. It would be possible if you were to create an HTML form where your users lay out the desired destinations. We could then use the information in that form along with Assembly Variables combined with more advanced FFmpeg settings to apply that kind of control.
But for the sake of simplicity however, let's look at some typical many-to-1 (5.1 to mono) channel audio downmixing.
We will be using it along with the
Note: merging all audio streams (vs channels) into one, is currently not possible.
