I have roughly seven hours of recorded interviews that need to be turned into a clean, text-based transcript for later research analysis. The files are far from studio quality—there is noticeable background noise in places and several different voices come in and out of each session—so automated tools are struggling. I therefore need the entire job completed manually by someone comfortable isolating overlapping speech, catching softer comments, and preserving the meaning of every utterance. Here is what I’m looking for: • A full, verbatim transcript delivered as either a Word document or Google Doc. • Clear identification of each speaker whenever the voice changes (simple labels such as “Interviewer,” “Participant 1,” etc. are fine). ...

I have several crystal-clear audio recordings that must be converted into polished, accurately punctuated text. Once we begin, I’ll share the exact lengths and preferred file format, but expect straightforward speech with minimal background noise. Here’s what I need from you: • A separate Word or Google Doc for each file, delivered in the same order I provide them. • Correct spelling, grammar, and punctuation throughout. • Speaker labels whenever more than one voice appears. • Optional two-minute timestamps—let me know if including them affects your turnaround. Because the audio quality is excellent, I’m aiming for near-perfect accuracy and a fast delivery window. When you reply, include your standard rate per audio minute and how m...

WebRTC Call Recording Issues in Desktop Dialer (JsSIP) We are working on a desktop VoIP dialer built using JsSIP and WebRTC and are facing multiple issues related to audio call recording that need to be analyzed and fixed.

I have an existing Angular application that already uses WebRTC, but connection drops, inconsistent audio-video quality, and some brittle glue code are hurting the experience for both our internal team and our external clients. I want the video-conferencing and voice-calling flows rebuilt so they feel rock-solid and native to Angular rather than an add-on. You will dive into the current codebase (Angular 18, TypeScript) to refactor the signaling layer, configure STUN/TURN properly, and tighten up state management so renegotiations no longer break active sessions. Expect to profile bandwidth, tweak codec preferences, and ensure the change detection cycle is not blocking media threads. Deliverables • Stable one-to-one and group video calls that recover gracefully from network blip...

I have a clip that was shot beside a busy street and the constant traffic rumble has buried both my questions and the guest’s answers. I need the traffic noise taken out and the dialogue brought forward so every word is clear and natural-sounding.

I have a short video clip whose dialogue is buried under wind noise. I must be able to hear every word clearly so I can understand what’s being said and recognise who is speaking. The source file is ready to share immediately. I need the voice isolated, the noise removed, and the volume leveled so normal playback on headphones or laptop speakers sounds clean and intelligible. A fast turnaround is important—ideally within the next day or two.

I already have two live avatars that mirror real people as they speak to one another, yet the current pipeline adds several seconds of lag. I need your help driving total end-to-end latency (mouth movement, facial animation, and generated voice) down to a hard ceiling of one second while keeping everything completely self-hosted—no paid APIs or usage-based services. The finished solution must plug straight into my existing platform and remain free for the public to use. You will begin by profiling the present stack, spotting where frames or audio buffers pile up, then redesign the generation and streaming loop so that speech-to-text, text-to-speech, facial blend-shape synthesis, and video compositing all run in near real time. GPU acceleration, WebRTC, low-level ffmpeg calls, on-dev...
