    I've also enjoyed Google's blob opera, for something similar!

    Thanks everyone for the suggestions and kind words.

    Some details:

    The source code for this project can be found on github [0].

    I am using an AudioWorklet node with custom DSP using Rust/WebAssembly. Graphics are just done with the Canvas API. The voice leading is done algorithmically using a state machine with some heuristics.

    The underlying DSP algorithm is a physical model of the human voice, similar to the model you'd find in Pink Trombone [1], but with some added improvements. The DSP code for that is a small crate [2] I've been working on just for singing synthesizers based on previous work I've done.

      Dear zebproj,

      Apologies for the late comment, but I had a query I wanted to share.

      Would it be possible for you to create a tool that allows users to mimic human emotional sounds directly in the browser? I’m thinking of sounds like realistic coughs, sighs, gasps, and other vocal expressions like shouting or crying etc . It would be amazing if the tool could optionally incorporate TTS, but even without it, the functionality would be very valuable for content creators or people who need custom sound effects.

      The idea is to let users customize these sounds by adjusting parameters such as intensity, pitch, and duration. It could also include variations for emotional contexts, like a sad sigh, a relieved sigh, a startled gasp, or a soft cough. An intuitive interface with sliders and buttons to tweak and preview sounds in real-time would make it super user-friendly, with options to save or export the generated audio much like the project pinktrombone

      I’m quite new to this field and only have basic experience with HTML, CSS, and JavaScript. However, I am very much interested in this area and I was wondering if this is something that could be achieved using tools like CursorAI or similar AI-based solutions? Or better yet, is it possible for you to create something like this for people like me who aren’t very tech-savvy?

      Thank you so much

        Greetings,

        What a beautiful idea. Sadly, I do not think I currently have the skills required to build such a tool.

        The underlying algorithms and vocal models I'm using here are just good enough to get some singing vowels working. You'd need a far more complex model to simulate the turbulent airflow required for a cough.

        If you suspend disbelief and allow for more abstract sounds, I believe you can craft sounds that have similar emotional impact. A few years ago, I made some non-verbal goblin sounds [0] from very simple synthesizer components and some well-placed control curves. Even though they don't sound realistic, character definitely comes through.

          Dear Zebproj Thankyou for the response. I see, do you believe that tools like cursor Ai or ChatGPT can help like you I too do not have the skills to make such a tool and while I am trying to get there it will be quite sometime if I can learn those skills and implement. I really wish if someone can make my wish come true I will still however have a look at what you shared cheers Alex

    95% of the time, I can only get 1 voice at a time. 5% of the time, I can get 2 or 3 voices at a time (1 variable pitch, the others fixed pitch) but I have no idea what input causes this rare behavior. Can you add some help text explaining what various input sequences will achieve?

    Android Chrome with touch input (Pixel 8 Pro).

      A tutorial would be helpful.

      Holding down a note and waiting will cause a second, then a third not to appear. When you move your held, note to another pitch, the other pitches will follow, but with a bit of delay. This produces what is known as staggered voice leading, and produces interesting "in-between" chords.

      • hunter2_12 hours ago
        Aha! In hindsight, I'm amazed that I managed to not figure this out on my own.

    Add "display:block;" to canvas to fix the issue with vertical scroll appearing. Also, you might want to consider looking into vh and vw units to fill canvas to viewport without using javascript.
    • skykooler1 day ago
      Is there a reason to avoid using javascript for canvas layout considering you need javascript to draw on the canvas in the first place?
    • zebproj23 hours ago
      Thanks, I'll look into it

    Source code is here: https://github.com/PaulBatchelor/Trio

    It's written in JavaScript and Rust (compiled to WASM).

    This is so fun. One note: on iOS Safari on my iPhone, it really believes I’m trying to select everything, do drag and drop, etc. I’m sure someone here knows the proper CSS incantation.
  • brunorsini1 day ago
    Fun! I'd love the option to increase (double?) range. It would sacrifice precision somewhat, so a toggle would be ideal.

    A toggle for quickly visualizing notes would also be useful, as well as keyboard shortcuts — perhaps while one clicks the mouse on a given note, pressing the keyboard shortcut for another specific note gradually moves pitch in that direction, with programmable speed.

    • brunorsini1 day ago
      Oh, and clicking multiple times at the leftmost portion of the instrument (around 1/4th from the top) sounds exactly like Laurie Anderson's classic "O Superman" :)

    This is awesome fun. Reminds of Google Blog Opera and Pink Trombone.

    Can we have multiple voices when using multiple fingers please?

    Edit: I can't sing or play music but this is making me feel like I am making someone sing nicely, it's relatively lot easy to play with.

    This is awesome! It would be great if you could record a snippet then layer your recordings.

    Very neat. Side note, but one of the more fun aspects of Garageband on the iPad is that you can load string instruments such as an Erhu and play it by physically sliding your finger along the string in a very similar way.
  • ldenoue1 day ago
    This thing is amazing can you add recording?

    Perhaps some samples you or visitors create?

    Then add a little sampler for beat and it’s a fantastic tool

  • fhackenberger1 day ago
    This is such a great way to practice! Thank you for creating it! Could you perhaps add pitch indicators on the side and multi touch support? Or maybe it's open source?

    in Chrome, on my iphone, I can get a cool effect that looks like a glitch, but I wonder if it is a feature. If I hold a note a certain way, where the browser does a “select all”, and then drag my thumb, it drags a thumbnail of the page. When I release it, it keeps the first note and starts a new one using the new position of my thumb. I can create my own harmonies this way instead of the default parts that appear when I hold the note in place.

    Does anyone make a USB Midi Theremin? That would totally be the right front end for this one!
  • makapuf1 day ago
    I'm sorry but I can see a small keyboard with selected notes, can some one describe what makes it 3 parts harmony ? Is it a song thing ? Some chord thing ? There is no description on the site or the github repo.
  • varunneal1 day ago
    so beautiful. I can imagine using this a lot if some buttons are added (start/stop harmony, view note/resonance, etc). great job
  • blaufast1 day ago
    Neat!
