Show HN: Web DSP audio editor

Creator here, happy to answer any questions! Here&#x27;s an example delay effect: <a href="https:&#x2F;&#x2F;dsp.audio&#x2F;editor&#x2F;QbQuSG8sMKsMnrqgf7NB&#x2F;1" rel="nofollow">https:&#x2F;&#x2F;dsp.audio&#x2F;editor&#x2F;QbQuSG8sMKsMnrqgf7NB&#x2F;1</a> Please feel free to use the tool to prototype or show your creations around.<p>— Please note that the app runs only on Chrome &gt; v66, for now, because Chrome is the only browser implementing the Audio Worklet[1] spec. Other browser will follow suit (hopefully) soon<p>[1] <a href="https:&#x2F;&#x2F;developers.google.com&#x2F;web&#x2F;updates&#x2F;2017&#x2F;12&#x2F;audio-worklet" rel="nofollow">https:&#x2F;&#x2F;developers.google.com&#x2F;web&#x2F;updates&#x2F;2017&#x2F;12&#x2F;audio-work...</a>

Creator here - thanks for the feedback!<p>For anyone interested on the stack, the visual part is React &#x2F; Redux SPA. I use Firebase&#x27;s Firestore as a DB (I wanted to try it and so far it&#x27;s really cool) and Google Cloud Functions for the APIs. The repo is hosted on Gitlab and is a Lerna monorepo, which is amazing.

This is great! I really hope developers keep pushing the webAudioApi. Its not hard to imagine serious browser based DAWs within 5yrs. I&#x27;ve been doing my webaudio experiments here: <a href="http:&#x2F;&#x2F;treblemaker.ai" rel="nofollow">http:&#x2F;&#x2F;treblemaker.ai</a>

This is cool and looks promising! If you want some DSP functions in JS, I had made some[0] in the past. They&#x27;re all MIT licensed and sometimes you would need to adapt the code a bit because of the imports and globals that are implicit as these were domain specific.<p>[0]: <a href="https:&#x2F;&#x2F;github.com&#x2F;opendsp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;opendsp</a>

(Chrome only)

Looks great!<p>Any chance of adding a piano roll for playing short melodies(and perhaps chords with the proper processor)?

You may like too this single file midi player that comes with a one line synthesizer<p><a href="https:&#x2F;&#x2F;github.com&#x2F;aguaviva&#x2F;SimpleMidi" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;aguaviva&#x2F;SimpleMidi</a>

This is great!<p>I especially like that you&#x27;ve included a share mechanism. I built an audio dsp playground before, but didn&#x27;t spend enough time on it to provide that.<p>Are you going to add a discovery page to browse people&#x27;s creations?

Nice. The only thing I don&#x27;t like about it is that its browser based, because - as a musician with a room full of hardware - its hard to get over the conclusion that browser-based music tools are simply not ready for production - i.e. I would never use this on stage or in the studio. Cute experiment though...

A sound engineering illiterate here. But, both the project and the new API from chrome looks like something very interesting that I&#x27;d not want to miss.<p>Can somebody ELI5 to me, what this is about? Or point me in the right direction perhaps.

Doesn&#x27;t seem to play on Android 6, Chrome.
