#2Author here. This is a basic spectrogram visualizer that's mobile friendly. It allows to select regions on the spectrogram and play them separately. There is no grand plan behind this web app: it's just a handy basic tool to capture sounds on your phone and see what they look like.

Looks like it says “mime type is not supported” on mobile Safari.

This is incredible! One of the best spectral tools I've seen.
Can we hire you to help us improve the (broken) spectral visualizations on our app?

I would so love to hire you to help us. This is freaking cool.
Even if you're not interested, mad props. I really love this.

#5Can you recommend any good references to begin understanding the Spectrogram ? I work in DL based Noise cancellation - major part of my work involves analyzing spectrograms - I find it very difficult to do my work without having an ability to critically analyze these images. Any help from anybody ?

I get the same error on Iphone/Safari

What do you mean by "understanding the Spectrogram"? The graph itself is straightforward: x axis is time, y axis is frequency. The intensity of each pixel represents the intensity of a certain frequency component and a certain point in time.
If you're referring to generating spectrograms with Fourier transforms, you will need some math background to properly do the calculation by hand. It largely just boils down to "find the amount of each frequency over time"
Last question, if this is the premise your work, shouldn't you know about it already?

#10Simple, straight to the point, and super useful.
One place I used these was on a toy AI assistant. I recorded myself saying a trigger word thousands of times, cut the audio in pieces and converted each to a spectrogram image. I then feed those to a training model to help recognize the trigger word.
Before the spectrogram, i was feeding the wav file directly, it was incredibly intensive on my laptop. But the image files were easier to process in real time. This tool can be used for debugging.
