Detecting Speaker Changes with Pyannote Segmentation 3.0 and ONNX Runtime
Hello, everyone. When listening to a conversation, we naturally keep track of who is speaking. A program has a harder job: beyond finding speech, it must also determine where one speaker gives way to another. Today, I will use an ONNX version of Pyannote Segmentation 3.0 to detect speaker changes in a two-person conversation and split the recording into one WAV file per utterance. What I Tested This lab uses FFmpeg to decode a roughly 14-second conversation into a 16 kHz mono waveform. It then combines the Pyannote segmentation model with simple post-processing to produce contiguous speaker segments. I wanted to verify: Whether six alternating utterances can be separated into six segments Whether the detected speaker indexes remain consistent throughout the recording Whether ONNX Runtime can process the audio faster than real time using only its CPU execution provider Whether every segment can be saved as a separate WAV file The complete code and reproducible environment are available in the pyannote-scd lab in kiarina/labs . This test performs segmentation using the model's speaker indexes. It does not compare speaker embeddings or run clustering, so it is not a complete speaker diarization pipeline that identifies the same person throughout a long recording. Reproducing the Lab You will need: mise uv FFmpeg curl The following commands fetch only this lab, download the shared test audio, and run it: git clone --depth 1 --filter = blob:none --sparse \ https://github.com/kiarina/labs.git cd labs git sparse-checkout set .gitignore .mise/tasks Makefile mise.toml \ 2026/07/04/pyannote-scd make download-test-assets mise -C 2026/07/04/pyannote-scd run On the first run, the task downloads the full-precision onnx/model.onnx file from onnx-community/pyannote-segmentation-3.0 on Hugging Face. uv then prepares the Python dependencies and runs the detector. How Speaker Segments Are Detected The input is this shared test asset: assets/mp3/conversation_2speaker_14s_16k.mp3 The re

Qtractor Usage Bible - Volume 1
QTRACTOR BIBLE Volume 1 — Foundations PART I — QTRACTOR CONCEPTS & WORKFLOW MODEL Chapter 1 — What Qtractor Is Quick Start Qtractor is a non-destructive, multi-track audio and MIDI sequencer designed primarily for Linux-based production environments. Unlike applications that attempt to integrate every aspect of the audio ecosystem into a single package, Qtractor focuses on recording, sequencing, editing, routing, mixing, and rendering while cooperating with external audio infrastructure and specialized tools. Qtractor is best understood as a timeline-centered production environment where audio clips, MIDI clips, plugins, automation, and routing configurations are organized into sessions. Common uses include: Music production MIDI composition Podcast production Voice recording Sound design Film scoring Hybrid hardware/software studios Live backing-track preparation Design Philosophy Qtractor follows several fundamental principles: Non-Destructive Editing Source media files remain unchanged. When a clip is trimmed, split, faded, moved, stretched, or processed, Qtractor modifies references and parameters rather than rewriting the original recording. Benefits include: Unlimited experimentation Reversible editing Reduced storage requirements Safer project management Session-Based Workflow Every operation belongs to a session. A session contains: Track definitions Clip placements Bus configurations Plugin assignments Automation data Routing information Tempo maps Markers Audio and MIDI source files remain separate from session instructions. Timeline-Centered Production The timeline is the primary workspace. Nearly every task ultimately relates to a position on the timeline: Recording Editing Automation Arrangement Export Qtractor is optimized for linear productions rather than clip-launching performance systems. Open Ecosystem Integration Qtractor assumes cooperation with: Audio servers MIDI systems External synthesizers External samplers Video playback tools Modular audi

🎮 Turing's Frequency — A Rhythm Game Where You Decrypt the Voices of History
🏆 This is a submission for the June Solstice Game Jam 🎯 What I Built Turing's Frequency is a browser-based rhythm game where you decrypt encrypted radio signals by listening to musical patterns and recreating them. Each signal carries a message from a historical figure who changed the world — voices that were silenced, ignored, or forgotten, now restored through your rhythm. 🎮 👉 PLAY THE GAME LIVE 👈 📖 The Story The game is set in 1954 , on the desk of Alan Turing at the University of Manchester. A radio crackles with fragmented transmissions — encrypted messages carrying words of Pride , resistance , and identity . You are a student who has found Turing's last notebook, and with it, the key to decrypting these signals. 🌅 The connection to the June solstice: As you decrypt each signal, the screen literally brightens — from near-darkness to a flood of golden light. The solstice is the moment light and dark trade places, and this game makes that transition tangible. 🎬 Video Demo 👆 Watch the full gameplay loop: title → story → rhythm gameplay → decrypted messages → victory screen with solstice light effect. 🕹️ How to Play Key Action 1 2 3 4 Play notes ↑ ↓ ← → Arrow keys (alternative) Space / Enter Advance screens 🎧 Listen to the signal pattern 🎹 Repeat the notes in order 🔓 Decrypt the message 🌅 Restore the voice 💻 The Code The entire game is a single HTML file (~32KB) with zero external dependencies . No frameworks, no libraries, no asset files — just HTML, CSS, and vanilla JavaScript. mamoor123 / turings-frequency Turing's Frequency - A Rhythm of Light. June Solstice Game Jam 2026 entry. ⚡ Key Technical Decisions 🔊 Web Audio API for all sound: Every tone is synthesized in real-time using oscillators.

Clean Audio Before Whisper: How Noise Removal Improves Transcription Accuracy (With Code)
Whisper is remarkably robust. But "robust" doesn't mean "immune to noise." If you've ever run a meeting recording through Whisper and gotten back garbage — or worse, confidently wrong text — the problem is usually the audio, not the model. Here's the thing: different noise types fail differently. Electrical hum causes Whisper to hallucinate syllables. Echo makes it drop words entirely. Static makes it confuse phonemes. Knowing which noise you have tells you exactly which fix to apply. This post covers: ✅ How each noise type (hum, hiss, echo, wind, static) degrades Whisper output ✅ A Python preprocessing pipeline that detects and removes noise before transcription ✅ How to call the StemSplit Denoise API for cloud GPU noise removal (no local setup) ✅ Measured WER improvements you can reproduce The Noise → Transcription Failure Map Noise Type What It Sounds Like How It Breaks Whisper Hum (50/60 Hz) Constant low-frequency "buzz" Inserts phantom syllables, lowers confidence Hiss High-frequency "shhh" Loses sibilants, confuses "s/sh/f" sounds Echo / Room reverb Words "bounce" and overlap Drops end-of-sentence words, merges phrases Wind Burst plosives, low-frequency rumble Transcribes as "[inaudible]", breaks sentence segmentation Static / crackling Random pops and snaps Breaks word boundaries, causes mid-word cuts These aren't hypothetical. They're reproducible failure modes. Let me show you how to handle each one. Prerequisites pip install openai-whisper requests python-dotenv soundfile numpy librosa You'll need: A StemSplit API key from stemsplit.io/developers (free 5-minute tier, no credit card) ffmpeg installed ( brew install ffmpeg / sudo apt install ffmpeg ) The Preprocessing Pipeline Here's the full pipeline before we break it down: Audio file → [Noise detection] → [Denoise via StemSplit API] → [Post-process: normalize, trim silence] → Whisper → Transcript Step 1: Detect What Kind of Noise You Have Before throwing everything at a denoiser, it helps to know what you
