Sox cannot determine type of file <p>I'm using node js and express with sox node bindings. I have a temporary uploaded file that I need to identify, but since the file does not have an extension, SoX gives me this error:</p> <pre><code>sox.identify(file, function(err, info) { if (err) { console.log(err) throw(err) } }); </code></pre> <blockquote> <p>sox FAIL formats: can't determine type of file C:\Users\User\Documents\Project\Media\temp\riqDeq15151sf14FWa</p> </blockquote> <p>I'm using <a href="https://github.com/expressjs/multer" rel="nofollow">multer</a> for saving the uploaded file temporarily. Is there anyway to have SoX identify the file even though it doesn't have an extension?</p>
