We want to create a mobile application similar to soundcloud, we want to upload sounds through applications or backend management and the backend will automatically perform the audio conversion, we can also upload videos that will be converted to audios, etc.
I would like to know which back-end structures would be more preferable.
1- You can use PHP + mySQL simple, use some cron jobs, etc. to fix audios, too obsolete,
2- Using Amazon or Google databases, however, you are not sure which back-end languages to use for better performance, Node? php? Python or any other
I would really like to get an idea from the older men.
