I'm looking for a way to get determine the size of a file in samples, ideally using javascript.

I am currently doing this using `new Buffer(bufferName).framecount()`, however the files I'm using are quite large (20-40 minutes long) and they can take a long time to load into a buffer, so I'm curious if there's a way to get the sample length without having to wait for a buffer to load? I'd ideally like to fill out my UI with some file data, and then load the buffer.

I see there is a way to get the location of the end of file in bytes using `new File(path).eof`, is that value something I could use? I don't know much about how to calculate this unfortunately.

Hi, did you try [sfinfo~]? I don't know how well it handles very big files. But if it does, it will give you length in ms and samplerate to calculate length in samples.

To use the bytesize to calculate length in samples you have to know some attributes of the soundfile before.

[sfinfo~] works well. I'd ideally like to be able to do it all in javascript, but I was able to write a function that messages an sfinfo and listens for it's output.
