当用户访问页面时，如何在 FireBase 上托管用户上传的 mp3 文件而不会很快耗尽带宽？

Question

My website provides artists with an audio visualization of their uploaded mp3 files. Firebase Storage isn't necessarily the issue, but rather a bandwidth. Every time a fan accesses the website, the website downloads the mp3 from Firebase Storage in order to access the frequency data to visualize it. Given each mp3 is ~8MB, you could see how even having 200 fans accessing the website would go over the 1GB free quota, so having thousands of people viewing the website would become expensive and not scalable. I've considered hosting on SoundCloud, but I wouldn't be able to download the mp3 data in that case, only stream. What do people commonly do in this situation, where they need to have larger files like mp3s downloaded to display to the user without quickly running out of bandwidth?

Answer 1

Firebase Storage isn't necessarily the issue, but rather the bandwidth. Every time a fan accesses the website, the website downloads the mp3 from Firebase Storage in order to access the frequency data to visualize it.

So most likely, that's why you're having that problem related to the bandwidth because you're downloading all audio files, each time a user opens the website. That's not how you should handle this kind of situation. Instead of downloading all audio files, you should only display the name of the files, and only download them on demand. For example, you should store the name of the files and corresponding URLs from Cloud Storage, either in Cloud Firestore or in the Realtime Database , and as soon as the user clicks the download/play button, only then does start playing/downloading them.

Given each mp3 is ~8MB, you could see how even having 200 fans accessing the website would go over the 1GB free quota, so having thousands of people viewing the website would become expensive and not scalable.

The problem isn't about scalability, it's about costs. Cloud Storage for Firebase can easily scale to millions of files. Besides that, please also bear in mind that the free quota, it's used for testing puposes and not for real-world applications. For that scenario, you should consider upgrading to the Blaze Plan .
