How to load peaks.json for each audio #77

Open gjzhappy opened 7 years ago

gjzhappy commented 7 years ago

If I want to load the peaks from server,how to make this happen?

naomiaro commented 7 years ago

Hi! Currently there is no support for loading a peaks.json type of file from the server at the moment.

I have always been hoping to add this in using formats available from this BBC tool: https://github.com/bbc/audiowaveform

Not sure when there will be time for this in the near future however.

gjzhappy commented 7 years ago

Actually I already generate the json file in server,but I can't find a method to load it as wavefurfer does.Is it possible to offer a method like load(mp3,json)?

naomiaro commented 7 years ago

It is possible, I'd like to add this functionality sometime soon. What format are you using for your json peaks file?

gjzhappy commented 7 years ago

I really appreciate your help ! Any format is OK as long as i can get the peak value.

@gjzhappy @naomiaro I created an api for audio to waveform json data output. https://waveform.al
