Toate localitățile din #Prahova afectate de criza de la barajul Paltinu au fost realimentate cu apă.
⚕️#DSP prelevează probe pentru a stabili dacă apa este potabilă.
I’m quite happy with the formula I found to tune a 1-pole/no-zero digital low-pass filter in the form y ← y + c * (x - y).
https://www.desmos.com/calculator/6bf88f2b35
It can set the cutoff frequency way above Nyquist and matches well the passband response of an ideal continuous-time equivalent filter (black curve). It is slightly shelf-shaped when the cutoff is close to Nyquist, but that’s the limitation of the lack of zero.
It’s a good way to tune the damping filter of a #reverb!
The formula remains fast to compute (a square root and a few mul/add). See Coefficient calculation > c5() and c3().
🏞️#MinistrulMediului, despre criza apei: Luni va putea să înceapă să curgă apa care este tratată, nu va ajunge în același timp în toate localitățile.
⚕️#DSP va avea ultimul cuvânt.
#DecemberAdventure 3rd evening + 4th morning
got #clive audio engine working on #Bela with clive (cross-)compiler running on desktop in a Debian Stretch chroot (matching the version of the Bela base system). very long setup instructions now in the README.md at
git clone https : / / code.mathr.co.uk / clive-core.git
compilation on desktop is much quicker than compilation on Bela (even with sshfs transfer overhead), allowing for lower #latency response to code changes.
no #OpenSoundControl #OSC server yet, because no #C11 <threads.h> support - switching to pthreads would probably be more portable...
clive is my thing for #LliveCoding #audiio #DSP in the #C programming language
idea: put the Bela context and audio block index n into the state struct, so that clive audio callback code can access Bela I/O other than stereo audio in + out.
this would be a backwards incompatible change, need to see how to minimize disruption... possibly it would be a good time to also expose the underlying block-based processing to the clive.c code, so that it can be inlined/loop-unrolled/etc for better runtime efficiency.

🌘 數位訊號處理入門：DSP 系統設計導論（第一部）
➤ 揭開數位訊號處理的奧祕：從類比到數位，設計你的第一個 DSP 系統
✤ https://www.analog.com/en/resources/analog-dialogue/articles/dsp-101-part-1.html
本文為數位訊號處理（DSP）系列文章的第一部，旨在為類比系統設計師介紹 DSP 的概念、優勢及應用。文章闡述了 DSP 處理器如何透過專為高速數值運算優化的軟硬體，即時處理類比訊號的數位樣本。與傳統類比濾波器相比，DSP 濾波器因其軟體基礎而更具彈性、可重複性且易於修改，尤其在高階濾波器設計上，DSP 展現出顯著的成本效益與穩定性。文中也介紹了兩種主要的 DSP 濾波器設計方法：有限脈衝響應（FIR）與無限脈衝響應（IIR），並探討了數位訊號處理的基礎，即即時訊號採樣，強調了採樣頻率對訊號還原精確度的關鍵影響。
+ 這篇文章真是 DSP 的最佳入門！終於瞭解為什麼現在的電子產品都離不開 DSP 了，原來軟體控制比硬體調整方便這麼多。
+ 對於類比背景的工程師

От модели в Engee до ПЛИС: как мы протестировали цифровые модуляции в реальной радиолинии

Erinnerung an die netten Seiten meines Ex-Jobs: #GUI-Designer und so… da fällt es leicht, eine Benutzeroberfläche für das #AllenHeathAHM16 #Mischpult zu bauen im #CustomControlEditor.
Das System ist sehr flutschig umgesetzt – sobald ich die Oberfläche ins #AHM uploade, lädt sie sich auf den Endgeräten neu.
Damit ist das Prototyping für ein dringend abzulieferndes Angebot für die #Installation einer laienbedienbaren #Sprachbeschallung erstmal abgeschlossen.
Schön auch, dass die Tools von #AllenAndHeath in #Wine laufen, so muss ich mein geliebtes #Linux nicht verlassen.
Das #AHM16 soll in meinem Stall dann eher so als #PaController / #DSP dienen – deswegen lebt mein Exemplar in einer mobilen Kisten zusammen mit einem schicken XLR-/Ethercon-Anschlussfeld.
Aber zum schnellen Ausprobieren von Installations-Ideen taugt dieses Setup natürlich auch.
Ein #AHM32 habe ich vor etwa einem Jahr in einer Mehrzweckhalle installiert, Betrieb bisher wartungsfrei.
Catching up on ADC talks - one pointed out that even at higher sample rates, when you're adding harmonics through any kind of distortion/non-linearity it's important to filter above 20kHz afterwards as the products will build up and reach the higher nyquist.

Tested #valhalladsp FutureVerb today. Sounds ... okayish. Uses a lot more CPU than the other reverbs (Room, Plate, VintageVerb), unfortunately. 😔
I still prefer VintageVerb and am quite happy with it. 🤗
Ja ist denn schon Weihnachten?
Tatsächlich ist der Gebrauchtmarkt wieder aktiver derzeit, da geht endlich wieder was.
Ich verkaufe zum Beispiel meinen IHOS DP4008 DSP / PA-Controller.

@bmaxv such a wide field. Anything specific of interest?
Alan Downey published a book many moons ago called Think DSP. Might be something that meshes with what you already explored

I seem to remember it was for python 2, but still worth checking out. #python #dsp #music #audio

This was part of my presentation at the Signal Processing Summit and DSP Online Conference presentation on simulating the tides by adding up sine waves.
