    Forensic Vocal Pattern Extraction
    6 días left
    Verificado

    I have a set of short, very muddy cell-phone recordings (saved as .m4a files) that need to be examined for forensic voice analysis. Simple EQ or noise-reduction passes are not enough—I have to isolate and document specific vocal patterns, phrasing and inflections, not merely boost overall speech frequencies. The task • Extract every discernible vocal event from the background clutter without introducing artifacts that could compromise admissibility. • Supply a clean, clearly intelligible file (24-bit WAV preferred) plus a brief technical note describing the methods you applied—spectral repair, adaptive filtering, machine-learning separation, etc.—so the chain of custody and methodology are transparent. Acceptance criteria • Target voice stands at le...

    Project Title: Firmware/Software Developer for "Emotion-First" Kid Companion Robot Project Overview: We are building the software logic for a "Kid Companion Robot V1." This is a desktop-sized emotional companion designed for children. Unlike Alexa or Siri, this robot does not use Generative AI, LLMs, or Machine Learning. Instead, it relies on a complex, deterministic state machine to simulate emotions, personality, and companionship. We need a developer to implement the "Emotion Engine," audio handling, visual eye rendering, and local voice command recognition based on a detailed behavior map. Key Responsibilities & Scope of Work: 1. The Emotion Engine (State Machine) You will implement a logic system that manages 27+ distinct emotional states (e.g., H...

    I need an n8n specialist to architect and deploy a full-fledged lead-management flow that revolves around Google Sheets as the master database. Today every enquiry lands in a single spreadsheet and, because we do not run a CRM, the sheet is the only source of truth—so the automation must start and end there with zero lead loss. Core objectives • Automatically capture every new row in the sheet, enrich it if possible, and trigger a personalised WhatsApp message series for timely follow-ups. • Record all subsequent calls, push the audio into a transcription service, and save the cleaned text back to the same lead record for easy reference. • Schedule nudges, reminders, and status updates so no prospect stalls unnoticed. Your workflow should cover: 1. n8n setup ...

    I have written a personalised song in English and already prepared a line-by-line Turkish adaptation. Now I’m looking for a versatile vocalist to bring the Turkish version to life in a polished Pop style. I’m happy to work with either a male or female voice; what matters most is clear Turkish pronunciation, good musicality and a modern pop tone. You’ll receive: • the original English demo (with melody guide) • the Turkish lyric sheet, perfectly aligned to the melody • a couple of reference tracks that capture the vocal colour and overall vibe I’m after What I need back from you: • a clean, fully-edited vocal recording (24-bit WAV) that sits tightly with the guide track • basic processing—pitch correction, gentle tuning and ...

    No Agency, Work on EST time zone. My project hinges on bringing Elevenlaps’ TTS API and TouchDesigner together in a seamless, real-time pipeline. I already have key scenes laid out inside TouchDesigner; what I’m missing is the connective tissue that calls Elevenlaps on demand, pipes the returned audio back into TouchDesigner, and keeps the whole loop responsive enough for live use. Here’s what I expect when we wrap up: • A well-commented Python DAT (or external script, if you prefer) that authenticates, sends text, receives the audio stream from Elevenlaps and stores it locally or directly in TouchDesigner’s memory. • A demo .toe file wired to play that audio synchronously with visuals so I can see the round-trip in action. • Clear setup notes so I c...

    I’m a YouTuber who wants immediate, practical coaching while I’m recording or live-streaming. The goal is a desktop application that lets me pick any connected microphone and camera, sends the live feed to Gemini (or the most effective alternative you recommend), and listens for moments where I can improve myself for the rhythms or anything else, listener-friendly rhythm. When that happens, the app should break could speak to me so I can correct myself on the spot. I work on both macOS and Windows. So I’ll let you decide what is the best. I’m happy with an Electron wrapper, a native Swift + .NET pair, or any framework you believe will keep latency low; just outline why you think it’s the best route. If the Gemini Live API is not yet public or stable, feel fr...

    For my university course project I must prove that a complete Power Automate flow can: 1. accept either a pasted YouTube link or an uploaded video in Google Drive / OneDrive, 2. pull or generate an English transcript, 3. translate that transcript to Russian, 4. synthesize a natural-sounding Russian voice-over, and 5. return both the .txt transcript and the Russian audio file to the same Drive/OneDrive folder (email copy is fine too). Right now I have no automated way to extract the text, so the solution needs to cover transcription as well as translation and TTS. You may use Azure Cognitive Services, Whisper, or any tool that fits inside Power Automate—just keep everything wired into my Microsoft 365 account; I’ll share temporary credentials as soon as we start. ...

    My Windows 11 PC suddenly lost all sound. Everything was working perfectly yesterday and I have not installed any new software, updates, or made configuration changes. What I have already tried: I rebooted the machine, double-checked all sound settings, updated the audio drivers in Device Manager, and went through every Microsoft-recommended step, yet the speakers remain silent. Setup details: The output device is a pair of wired desktop speakers connected through the standard 3.5 mm jack. No headphones or HDMI audio are in use. I need a Windows 11 audio expert who can quickly identify and resolve whatever is blocking playback—whether that’s a service issue, driver conflict, registry glitch, or deeper system corruption.

    I am looking for a committed business partner to continue and grow an existing DJ software project. Sadly, the original lead developer passed away. Since then, I have tried to keep the software running on my own, but I have come to realize that I cannot maintain and develop it at the required technical level by myself. Therefore, I am looking for someone who is not just a developer, but someone who truly has a passion for software development and audio programming. You should have strong experience with Delphi, C++, and audio programming in general. More importantly, I am looking for someone who is willing to take responsibility, think independently, and go the extra mile when needed. This is not a typical freelance job — it is a long-term partnership. What I can offer: • Eq...

    I need a repeatable way to turn my desktop display into a 720p stream that my existing DVR can pick up and record reliably. The goal is purely archival—no live monitoring or public broadcast—so stability and perfect sync between audio (if included) and video matter more to me than squeezing every last pixel. Here is what I already know and have on hand: a Windows-based PC and a Hikvision DVR that happily discovers ONVIF cameras. What I do not have is the know-how to bridge normal screen-capture tools (OBS, FFmpeg, or anything you recommend) with an ONVIF-compatible transport so the DVR treats the feed like any other IP camera channel.

    I need a reliable UART-based EQ link between a Texas Instruments chipset and an Android device. The goal is straightforward: move data in both directions so my custom Android app can issue real-time control commands and, when required, push or pull compressed audio signals over the same line. Your job is to deliver the Android-side software stack—driver layer, JNI/NDK bridge if necessary, and Java/Kotlin interface—so I can drop the library into my existing project and start talking to the TI part immediately. The link must handle baud-rate negotiation, framing, CRC, and graceful recovery from line noise. For proof, you’ll provide: • Source code and a sample APK that opens the port, sends a command packet, and plays back a short audio frame returned by the chi...

I do not have a separate audio stem—only the full video file—so the enhancement needs to start from that source.
