A waveform is a physical representation of the shape and form of an audio frequency. You see them a lot with popular music services like SoundCloud. We recently added the ability to render a waveform PNG as an output of your source audio. Below is an example of a waveform. This example is Iron's Butterfly's epic Rock Saga, In-A-Gadda-Da-Vida.
Using our API, it's very easy to render waveforms. Let's take a look at sample code.
png
500
50
FF0000
4
Simply specify the output as waveform, the codec as PNG, the height and width (in pixels), the color (using hex values), and set a factor (positive integer) for the level of anti-aliasing. It's that easy.
If writing code is you not your thing, try our User Interface. All of the waveform parameters are just a click away.
This is one of the many unique features we offer. Sign up today to get your hands dirty testing features with our forever free account.
