#CHROMATIC TUNER VIOLIN ONLINE CODE#

Because that's all you need to tune a violin! And since I'd done no research on how SEO actually works, I figured I'd publish the site, tell a couple people about it (Google would notice the traffic via analytics of course) and then I would call it a day. That's it - just a single button in the middle of the screen with a volume slider. The original vision for the tuner was a single page site, created with Angular that would look like this: My journey learning search engine optimization (SEO) and this application can be traced back to when I knew absolutely nothing about it - and I don't claim to be an expert now, but I like to think I've picked up a couple tricks along the way. All the programmer has to do is first initialize the audio context and pass it as the sole argument of the Sound class.

The code snippet below provides a class with methods that control the AudioContext(). This technology has become mainstream, and has been integrated by different browsers, such as Chrome, Safari, Firefox, Opera, and Edge, at different times over the past couple years. Finally, the signal is emitted through the final node, which are the speakers of the user's device. Next, the signal travels through another node, a gain node, which controls the volume of the waveform. Using the simplified diagram above, we start with a source: for it's an oscillator (also a feature of the Web Audio API), which can produce different kinds of waves (square wave on ) at any frequency. Image credit 's article on Web Audio APIīasically, an audio context defines a set of nodes to create sounds. Here's an excellent article on Audio Context that explains the concept: 'Audio Context' is the core concept used by a relatively new feature of browsers called 'Web Audio API', where API stands for application programming interface. Admin: Angular (built a simple admin with Firebase Auth).The introduction and features section of this article also show some of the useful features of the Web Audio API over HTML5 audio. The input tone frequency can be analyzed to create a chromatic tuner, which is a future goal for this project. I think one of the biggest benefits of using AudioContext is that one of the AudioContext nodes can be a microphone from the user's device.

By contrast, a tone created by an oscillator node in an Audio Context will play continuously, and perfectly at the programmed frequency until the user decides they want it to stop, without having to switch pages. These pre-recorded tones work okay, but you'll notice that the get-tuned tone has an annoying repeat loop, and the violinonline tuner takes you to a different page altogether.

Here's two examples: get-tuned html5 violin tuner and violinonline tuner. In some cases, the website creators recorded an oboe playing whichever tone they wanted to provide as a tuner. Other tuning sites use the HTML5 tag to play a prerecorded source, or they'll link to an MP3 file which plays through an audio player on the browser.

Create something that is more user friendly than the competition.

I found myself needing a tuner with none around, so I'd often turn to searching Google.

But I quickly realized that it would be very difficult to get traffic on a site with a single page. Tune Anything was originally intended to create a better violin tuner.
