Freelancer vs Upwork (2026) - An Honest, Side-by-Side Comparison for Businesses and Freelancers
Audio Processing is a field at the intersection of mathematics and engineering that focuses on the capture, synthesis, analysis, and manipulation of audio signals. An Audio Signal Processing Expert is a person well-versed in the field and has the ability to create solutions that can shape, record, alter and delete sounds for almost any application. This expert can analyze and record music, speech and other environmental sounds, as well as design virtual sound environments through speakers or headphones.
Audio Processing requires sophisticated algorithms and calculations used to process audio signals in real time or in post production. It is used in a wide range of applications such as improving user experiences on social networks and streaming websites, creating complex virtual worlds used to train AI models, developing interactive music systems or sound synthesisers that mimic musical instruments or even developing music remixes from existing recordings.

The project focuses on collecting natural code-switching conversational audio, where speakers alternate between two languages within a single conversational turn. Scripts will be provided; however, natural delivery, fluency, and context-appropriate language switching are essential. Language Requirements Primary Language (Native level – one required): Catalan (ca-ES: ...
I’m running this project on behalf of a recruitment agency that specializes in voice-data collection. Our end goal is to gather 8,000–10,000 UNIQUE speakers with a clear, native-or-fluent US English accent. Project snapshot • Each contributor records 20 very short sentences such as “Hi Alexa, how are you?” using the web recorder and script we supply. • The whole task takes 3–5 minutes per person. • Accent quality is confirmed through quick voice-sample tests before full recording. • We run strict database cross-checks to guarantee that nobody records twice, and any duplicate voices are automatically rejected. What I need from you I’m looking for partners—other recruitment agencies, voice networks, universities, or large-scale ...

I want PCB design to order from JLCPCB. PCB combines an Ai-Thinker VC-02 Offline Voice Recognition Bare module with a CH32V003F4P6 MCU. The board will accept 5 V DC, step it down to 3.3 V through an AMS1117-3.3, and exchange UART data between the VC-02 and the CH32V003. Eight digital inputs—each pulled low to GND on trigger— to CH32V003. CH32V003 must switch eight relay (on the same PCB, sugar cube 5v relay) outputs that are driven in one neat block through a ULN2803ADWR. To make the VC-02 fully usable I need its programming port (TX, RX, VCC, GND), a speaker connector and a microphone connector on the PCB. A second programming header exposes PD1, VCC and GND for the CH32V003. All connectors together total six ports: 9-pin input (8 input and GND for return line to 8 input), bo...
Hoping to have an ebook made into an audiobook using elevenlabs. I am aiming for a first draft using a generic AI voice then a 2nd draft (with edits) using voice cloning with my own voice. is linked below as well as a trial I did myself through elevenlabdw using my preferred first draft narrative voice (Liam).
I'm looking for a professional to evaluate the impact of new carpet flooring on our church's audio quality in the main sanctuary hall. We are considering tile and/or carpet and are wondering if this will affect the sound quality in the service. Currently, we have a combination of tile and carpet that, due to the age of the church, experts have stated may contain asbestos. We will be removing said carpet/tile, testing for asbestos, and then installing new flooring after it is determined that there is no danger of asbestos contamination. We would like a consultation on what direction we should take with the new flooring. The demographic of our congregation is mostly elderly, for which we would like to choose flooring that will not be detrimental to the sound quality of our audio eq...
Job Title: Build Self-Hosted Audio Content Recognition (ACR) System for 10–20 Live TV Streams – Real-Time Music Detection + Dashboard Job Type: Fixed Price Budget: $2,000 USD Location: Remote Project Overview We are looking for an experienced freelancer to build a complete real-time monitoring system that watches 10–20 live TV channels simultaneously. The system must record every stream, analyze the audio on the fly using a fully self-hosted audio fingerprinting engine (Shazam-style, NO cloud APIs like ACRCloud), detect specific songs or audio segments, and instantly log exact timestamps on a clean web dashboard. This is a production-ready project starting with a quick Proof-of-Concept (POC) and then scaling up. Stream Sources M3U8 live streams from JioTV (you must integ...
I have a single high-res illustration of my bear mascot, Roji (glasses + graduation cap), and I want to bring him to life inside my Vite + React web app using the Rive runtime. Starting from that flat image you will: • Isolate and prepare the artwork layers so every limb, facial feature, cap, etc. is independently controllable. • Rig the character in Rive, setting up bones, constraints and mesh deformation for natural movement. • Animate a complete set of state-machine driven actions: idle, listening and speaking, plus the specific gestures I need—wave, nod, dance, jump, cheer—as well as facial expressions like smile and frown. • Create mood states (Happy, Sad, Excited, Curious/Thinking) that can blend with those actions. • Wire a parameter in ...
I need a compact 2-4 channel analog MEMS microphone array built around an XMOS processor. The board must perform real-time beamforming, echo-cancellation and noise-suppression, then expose a clean audio output through straightforward header pins so it can be patched into downstream hardware without fuss. Size matters here: the smaller the PCB, the better. I’m expecting you to handle the full hardware cycle—schematic capture, PCB layout, component selection and a ready-to-order BOM—plus the XMOS firmware that brings the DSP features to life. Your code should compile and run on the free tools from XMOS; please include any scripts or tuning utilities you rely on. Deliverables • Production-ready Gerbers, pick-and-place file, annotated schematic • BOM with supp...
Wir entwickeln ein Music Tech Produkt, das die komplette Signalkette von E Gitarre und Bass bis zum Lautsprecher in einem System abbilden soll. Das System vereint kabellose Übertragung, Echtzeit Audio Processing, ein App Interface für Presets und Steuerung sowie eine Plattform Perspektive, sodass Sounds und Setups reproduzierbar werden und später erweitert werden können. Unser Fokus liegt auf einem bühnen und tourtauglichen Workflow, der auch in realen und stark gestörten 2,4 GHz Umgebungen stabil funktioniert. Es existieren bereits Hardware Prototypen und mehrere Iterationen von Sender und Receiver, unter anderem auf Basis von STM32 und ESP32. Die Zusammenarbeit ist auf mindestens zwölf Monate ausgelegt. Für die Rolle gibt es die Möglichkeit, ...
I’m building a browser based demo where a pre-made 3D character reacts to anything the user says. When the visitor presses a “talk” button, the microphone audio is captured and audio passed to the character’s mouth so the lips match the speech. Live audio to lip sync of character. Which could mean that the audio is analysed, phoneme / viseme data is extracted, and the character’s blend shapes / mouth poses update in sync. I’m open to whichever phoneme-detection approach you prefer so long as the lip sync looks believable. We can buy a 3d model / avatar if you share a link. It could be of just a head with the lips moving. Scope you’ll handle – Integrate Web Audio for capture. – Implement or wire in the phoneme-mapping logic that...
I have several English-language recordings that need to be turned into clean, accurate subtitle files. The task is straightforward: listen to the audio, transcribe every spoken word verbatim, and format the text so it can be dropped straight into a subtitle editor (SRT or VTT is fine). Because these files will serve as on-screen captions, timing matters as much as the words themselves. I need each subtitle line to sync naturally with the speaker’s pace and to follow common readability rules—roughly two lines per frame, no awkward breaks, and clear identification when multiple voices overlap. Deliverables • Completed transcript in SRT or VTT with precise timestamps • A plain-text version of the dialogue (for reference or future repurposing) If you’re comfort...
