meyda VS wam-openstudio

Sounds like a job for web workers. Do you have any examples? I'd love to check them out. I've seen some sequencers but never a full-blown DAW attempt. I've been toying with a couple browser-based, realtime audio ML ideas lately (mostly porting some models to Tensorflow.js), so my interest is piqued.

As far as libraries go for analysis, the only solid option I've found so far is Meyda[0]. I was drawn to it mostly because it closely maps to librosa[1], and it seems fairly mature. Does anyone have any others that may come in handy for this kind of work? This is just free-time tinkering for me. I'm completely new to the space.

It was pretty hacky really. There's a javascript library called Meyda that does audio processing and their front page has this visualization, i was just careful in my cropping. :). I should really give them credit in the description.

I recently published a beta build of Meyda to the npm registry, with the intention of having one of our longest running users test it out to make sure it worked in their project. I hadn't done a manual release in a long time, since we use semantic-release, so I skimmed the output of npm publish --help, and figured out what command I would run. I set the version field of package.json to 5.1.7-beta.0, as instructed built the bundle, ran our test suite, and ran npm publish . --dry-run, to verify that the manifest of files that would be published was correct. It was correct, and so I ran

If you're using Meyda to analyze audio that you load in this way, you will need to make sure that the sample rate of the audio matches the sample rate that Meyda is set to use. Otherwise you'll end up with audio features that are incorrect, and based on a skewed frequency scale. You can either match the Meyda sample rate to the wav sample rate, or you can resample the audio to fit a standard sample rate (i.e. 44,100hz, or 48,000hz). Resampling audio is a complicated topic beyond the scope of this article, but if you have trouble finding information online, let me know and I may find time to write an article.

We started writing a web-based DAW prototype that relies on the Webaudio Modules version 2.0 (a standard for plugins/hosts on the Web, that can be developed using a large variety of languages/approaches). For the moment, the DAW has very limited features but 1) Each track is written as an AudioWorklet, and sample accurate processing is being done for playing each track. That means, that from the processor part of each track player, we can schedule events (automation, midi, etc) to plugins. We can also loop and edit the audio track with a sample accuracy (this is not done yet, but everything is ready for that. We will add this soon). 2) Each track is associated with a plugin chain. Plugins are WAM plugins (webaudiomodules), and can be automated. 3) There are quite a lot of plugins already available in the WAM format, most effects, instruments. The WAM distribution comes with a set of example plugins + the FAUST IDE can generate WAM2 plugins in seconds. All running DSP in WASM. We (WAM designers, implementers and maintainers) can be reached on a slack channel (#webaudiomodules, subchannel of the #webaudio channel.

The WebAudioModules distro is 4 GitHub repos, it is also available as npm modules. (https://github.com/webaudiomodules, start by building the wam-example one and run the examples). You can find some presentations on youtube (such as: https://www.youtube.com/watch?v=8G3we8dikq8).

DAW prototype (should be included soon in the wam-example repo): Picture : https://i.ibb.co/mBdNGqk/WAM2-DAW.jpg online version: https://wam-openstudio.vidalmazuy.fr/, current repo (work in progress, as I said, this work is active and we do plan to add all missing functionnalities the upcoming months) https://github.com/TER-M1/wam-openstudio

There are also professional, commercial DAWs, not open source ones, such as https://ampedstudio.com/ that is also capable of loading WAM plugins, and is developed using the same approach as our DAW proto (host as AW), bandlab.com or soundtrap.com.
