Python / Django中的音频波形可视化 [英] Audio waveform visualisation in Python/Django

问题描述

我已经看过Stack Overflow的一个答案，但是没有任何地方可以给出正确的答案或方向...

I've looked around Stack Overflow for an answer to this, but nowhere seems to give the correct answer or direction...

我的项目将允许一个用户上传WAV，最终将在服务器上使用FFmpeg将其转换为低质量的MP3，并将它们全部存储在Amazon S3上。下一个障碍就在于如何从上传的声音中提取可靠的波形可视化。我在Linux上使用Python和Django在这个项目的VPS上的Ubuntu 10 ...

My project will allow a user to upload a WAV, which ultimately will be converted to a low quality MP3 using FFmpeg on the server and it'll all be stored and served on Amazon S3. The next obstacle is working out how to extract a reliable waveform visualisation from this uploaded sound. I'm using Python and Django on Linux Ubuntu 10 on a VPS for this project...

I'm, at the vert least, needing some sort of direction... I'm at a lost of where to start to look for such a tool?
