I am looking for a practical program that listens to any TV show, movie, or song while it plays and instantly mutes the audio a split-second before a whistle reaches the speakers. The goal is to let a family member with Tourette’s enjoy their usual entertainment without the trigger ever being heard. Scope of work The solution must monitor both streaming services (think Netflix, Disney+, Spotify, YouTube, etc.) and local media files (MP4, MKV, MP3, WAV) on Windows and MacOS. Live broadcast support is not required at this stage. Core requirements • Detect the acoustic signature of a whistle with near-zero latency. • Drop or duck only the whistle portion, keeping the rest of the soundtrack intact. • Work transparently in the background, so users can keep using their preferred player or browser. • Simple start/stop interface plus an on-screen indicator that shows when a whistle was caught. • Lightweight install packages for both operating systems. Acceptance criteria 1. A compiled installer (EXE and DMG) that a non-technical user can run. 2. Real-time testing: when I play sample clips containing multiple styles of whistling, the program mutes each whistle and unmutes automatically once it has passed. 3. No noticeable desynchronization or overall volume loss to the rest of the content. 4. Source code with clear build instructions so future updates are possible. I’m open to whichever tech stack you believe best meets these needs—DSP libraries, machine-learning models, virtual audio drivers, or browser extensions—as long as it can deliver reliable, low-latency results on both Windows and MacOS. Please outline your approach, any similar work you’ve done, and an estimated timeline for a working prototype. Together we can make everyday media safe and enjoyable again.

Hello, I have carefully reviewed your requirement for a real-time whistle auto-mute application and understand the importance of ultra-low latency and reliability for everyday media use. With 10+ years of experience in audio processing and cross-platform software development, I can build a practical solution for both Windows and macOS. My approach would use a lightweight background service combined with a virtual audio driver to capture system output audio in real time. A DSP-based whistle detection model (band-pass frequency analysis + transient detection, optionally enhanced with a small ML classifier) will identify whistle signatures with near-zero latency. Upon detection, the system will momentarily duck or mute only the whistle frequency band, then automatically restore normal audio without noticeable desynchronization. The application will include a simple start/stop interface, live detection indicator, and packaged installers (EXE + DMG). The solution will support streaming platforms and local media transparently, without modifying browsers or media players. Full source code and documented build instructions will be delivered. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. Thanks.

Hello, I’m excited about the opportunity to contribute to your project. With my expertise in cross-platform audio engineering, real-time DSP/ML, and desktop application development, I can build a whistle-detection and “duck/mute” system for local media playback and user-routed audio, with a simple start/stop UI and clear on-screen detection indicator. I’ll tailor the solution to low-latency performance by using a lightweight whistle classifier (spectral features + small model) and a configurable attenuation envelope so only the whistle band is reduced while the rest of the soundtrack stays intact, with no noticeable desync or global volume loss. You can expect clear communication, fast turnaround, and a working prototype plus source code and build instructions, packaged for Windows and macOS using a supported audio pipeline (local file player or explicit user-selected audio route) that keeps the setup reliable for non-technical users.

Hi there, I will build your whistle auto-mute tool for Windows and MacOS — a background service that captures system audio through a virtual audio driver, runs it through a real-time whistle detector, and surgically ducks only the whistle frequencies before passing the audio to the speakers. The app will include a minimal system-tray interface with start/stop control and a live indicator showing each detected whistle. For detection, I will use a lightweight spectrogram classifier trained on whistle samples. Whistles occupy a narrow frequency band (roughly 500 Hz to 4 kHz with strong harmonic peaks), making them distinguishable from speech and music with high accuracy. By processing in overlapping 10-20 ms frames, the system will catch a whistle onset and apply a targeted gain duck within one frame — fast enough that the whistle never fully reaches the listener. Questions: 1) Are there specific whistle styles that trigger the response most — human lip whistling, tea-kettle sounds, or both? 2) Should the indicator log timestamps so you can review which moments were caught? 3) Do you have sample clips with the triggering whistles I can use for training and testing from day one? Looking forward to discussing further. Best regards, Faizan

Greetings, I once built a small audio tool that sat in the background and caught a few very sharp sounds in real time, using a mix of DSP filtering and a tiny classifier, and it had to work without breaking sync. That kind of low-latency audio routing and clean on/off control is very close to what you need here. The main challenge is speed because you need to detect the whistle before it reaches the speakers, so I’d route system audio through a virtual driver, run a fast whistle detector, then apply a very short duck or mute window only on the whistle band and release instantly after. I can have a first working demo in about 10 to 14 days that runs on Windows first, then bring the same core engine to macOS right after, keeping the app light and transparent. Do you already have a small set of whistle examples that are known triggers for your family member? Sincerely, Oleksandr

I have extensive experience developing low-latency audio processing tools, including similar triggers for noise-gate automation and environmental sound recognition. Developing an auto-mute program for whistles requires a sophisticated approach to signal processing to ensure that the system triggers only on intentional whistling while ignoring high-pitched background scores or dialogue. My background in Python-based DSP (Digital Signal Processing) allows me to build a lightweight, efficient utility that monitors your system’s output without impacting performance or causing audio delay. To achieve this, I will implement a real-time audio stream listener using PyAudio or the SoundDevice library, feeding the data into a Fast Fourier Transform (FFT) engine to analyze frequency peaks in the 500Hz to 4000Hz range. By calculating the spectral flatness and the Q-factor of incoming signals, I can distinguish the pure tones of a whistle from the broader spectral density of movie music or sound effects. I will utilize PyCaw or OSAScript to interface directly with your system’s master volume control, ensuring the mute command is executed in under 100ms. I can also build a custom calibration routine into the software, allowing the algorithm to "learn" the specific acoustics of your environment and minimize any potential false positives during intense action scenes or high-frequency musical passages. Do you need the mute to be momentary (unmuting as soon as the whistle stops) or a hard toggle that requires manual intervention? Additionally, would you prefer a minimalist system-tray application or a full-featured dashboard where you can adjust detection sensitivity and frequency thresholds? I am available to discuss the specific technical constraints of your setup and can walk you through my proposed architecture in a brief call or chat to ensure the final product integrates seamlessly with your daily media consumption.

I build lightweight, background tools that work with popular media players without forcing changes to user workflows. For Whistle Auto-Mute, I’ll design a cross‑platform real‑time whistle detector using optimized DSP (and optional ML as a fallback) to mute only the whistle segment with near-zero latency, while preserving the rest of the soundtrack. It will run transparently on Windows and macOS, either via a virtual audio sink/driver or seamless integration with existing players. A simple start/stop interface with an on‑screen whistle indicator will meet the UI goals. I will deliver EXE and DMG installers, plus source with build instructions for future updates. I can handle this with a clear testing plan and milestones, including prototype delivery within a defined timeline based on your feedback. Best regards, Billy Bryan

Hi. I can develop a low-latency audio filtering application for Windows and macOS to protect your family member from whistle triggers. I have the necessary knowledge of digital signal processing and cross-platform audio routing to build a background service that monitors and mutes specific acoustic signatures in real-time. My plan involves using a virtual audio driver (like VAC for Windows and CoreAudio for Mac) to intercept system sound and pass it through a Python-based DSP engine using a rolling buffer. I will implement a pre-trained machine learning model optimized for millisecond-level inference to detect whistles and trigger a temporary gain ducking before the audio reaches the physical speakers. I am available to start immediately and can prioritize a working prototype that demonstrates the detection accuracy and latency management. Excited to hear from you, Nehal
