librosa/librosa: Python library for audio and music analysis
In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.
Glicol looks very cool! Also check out Faust if you haven't (https://faust.grame.fr), another FP sound programming language.
Project mention: Show HN: Render audio to HTML canvas using WebGPU | news.ycombinator.com | 2024-04-15Nice! Great project website styling and demo.
I had a WebGPU scope demo using vanila JS here, but it's not connected to AudioContext at all.
https://stackblitz.com/edit/vitejs-vite-cuc9vs
Still, I had to use the old WebGL solution for https://glicol.org since the WebGPU support seems to be pretty slow at the moment.
Project mention: Need to send an I2S audio stream from an MEMS Microphone to Mobile app using ESP32 Bluetooth Realtime. Need some advice! | /r/esp32 | 2023-05-20Have you found Phil's audio tools for Arduino, they work great on ESP32. https://github.com/pschatzmann/arduino-audio-tools
Songmastr is a web-based AI mastering tool. Utilizing the power of the open-source Python library called Matchering, Songmastr is able to create a masterful audio track that matches a reference song of your choosing. The algorithm studies the RMS, FR, peak amplitude and stereo width of your reference track before applying it to the target audio file.
Project mention: Ask HN: Manufacturing somewhat novel MIDI controller | news.ycombinator.com | 2023-11-10You are about to bite off a lot. Ignore all the other advice in this thread, I do this for a living.
You have some software experience, this is good. Assuming you have embedded software experience (which is essential for what you are doing and not at all like web programming) you have a foothold to finish this project without going completely insane.
Hardware is a completely different beast. With software everything happens in your head and when you get stuck you can usually think your way out of it. With hardware, you really do need to learn to do things meticulously and step by step. There are many things that can go wrong. You will learn a lot on this journey.
Don't be afraid to ask for help. Finding a hardware community will be essential to do this as you learn the skills you need. You're going to make a lot of mistakes, best to go in embracing it
A good place to start is to join an open source community for MIDI. Two off the top of my head is http://www.ucapps.de/ for MIDI specific hardware and https://www.electro-smith.com/daisy
A large amount of the work you will find yourself doing at the beginning is just figuring out where and who to ask questions about things like the keybed and other hardware issues. None of this is terribly 'hard' but none of it is easy. Most of it comes from experience.
It is almost always best to use someone else's product when you are designing your first. Roger Linn (https://www.rogerlinndesign.com/) gave me some fantastic advice a couple years ago when I was trying to design switch caps: "Do you want to be a company that designs switch caps or one that designs synthesizers?" and that stuck. I don't want to design switch caps, so I bought them off the shelf, contracted someone to design my own, and moved on.
So to that end... just buy a couple keybeds from Fatar or someone else, or just grab a synth you already have or buy one off ebay and harvest the keybed from that (often times much cheaper than buying direct!)
Don't be afraid to spend money on tools. If you find something difficult, like soldering, I have not once regretted spending money on better tools. They grow with you and save you hundreds if not thousands of hours of unnecessary frustration. When you know you need a tool, find a way to get it.
Maybe I should make a blog post about this... hmm
Hope that helps!
I'm using JamesDSP with Pipewire. EasyEffects is the successor of PulseEffects for Pipewire.
Project mention: [Suggestion] Remove screen capture restriction on Spotify | /r/xManagerApp | 2023-12-09
Project mention: Recent improvements to OctaSine (free and open source FM synth plugin): new waveforms, pitch bend, velocity sensitivity and more | /r/synthesizers | 2023-05-28Since I last posted here, I've implemented multiple features for OctaSine, a free and open source frequency modulation synth plugin (VST2, CLAP), some of which were heavily requested.
Project mention: Receiving Weather Satellite Images Using SatDump | news.ycombinator.com | 2024-02-09GOES sats are geostationary but the NOAA APT satellites are encircling the planet and you can pick them up. Old tutorial but still relevant, just use "noaa-apt" tool[0] instead of WXtoImg. https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...
