I run a small 10x10-foot TikTok studio and I’m ready to tighten up my audio chain. All the gear is here—Shure MV7 (XLR), Elgato Stream Deck, Wave Link, OBS, TikFinity, Voicemod, and a pair of Bluetooth in-ear monitors—but I need someone to come onsite and make it all talk to each other. Here’s what I’m after: the Shure MV7 and Stream Deck must feed cleanly into TikTok Studio while also reaching my Bluetooth IEM with zero noticeable latency. The Stream Deck is mainly there for sound effects and overall audio control, so its profiles and key assignments need to be mapped through Wave Link and reflected in OBS and Voicemod without any volume jumps or channel conflicts. Physical cabling, software routing, gain staging, filter setup, and basic noise reduction all...
I’m building a new voice-recognition model and need a reliable partner to supply clean, clearly-spoken utterances. You’ll record a set list of short phrases that I’ll provide once we start. Each file must: • be recorded in a quiet environment, 16-bit, 44.1 kHz WAV or higher • contain only the target phrase—no lead-in or trailing noise • match the naming convention I’ll share so I can drop them straight into my training pipeline After you upload the batch I’ll run a quick acoustic check; if everything passes, the job’s complete. Let me know what microphone set-up you have and how quickly you can turn around approximately 200 lines.

I have multiple camera angles and separate audio tracks from my sister’s wedding and I want them woven together into a cohesive, traditional-style keepsake. The finished piece should run somewhere between 10 and 30 minutes—long enough to capture the day’s key moments without feeling drawn out. The entire wedding ceremony and the full speeches during the reception should be edited and included in their entirety. Then take some other videos and photos from the reception to flesh it with the key memories and to communicate the energy and feel of the night. You will receive: • Raw video files (with audio) from 2 cameras covering the ceremony, speeches, first dance, and reception highlights. The DJI video was recorded using D-LOG M (10-bit) so it will require some ...
.Hello, I am looking for a forensic audio examiner to review a recording that may be used in litigation. The issue is whether the recording is continuous or whether there are signs of stopping, pausing, restarting, splicing, editing, exporting, or other manipulation. I also need the metadata reviewed, including recorded date, encoded date, tagged date, and any signs that the file may not be the original recording. Can you please let me know: Whether you perform forensic audio authentication; Whether you can provide a written report suitable for court/litigation; What file format or original source material you would need; Your estimated cost and turnaround time
I’ve got a single 65-second music track that I captured in my living room. The performance is there, but the raw file still sounds like it was recorded exactly where it was—at home. I’m looking for your audio-engineering skills to transform it into a mix that could pass for a professional studio session. Here’s what I specifically need: • Noise reduction • Equalization • Volume leveling Feel free to add tasteful compression, subtle spatial effects, or gentle mastering touches so long as the end result remains true to the original vibe while gaining that polished, radio-ready sheen. Deliverables • Clean, fully processed stereo file in WAV (16- or 24-bit) and high-quality MP3 • One concise summary of the steps or plugins you used ...
I have a short video whose dialogue is masked by noticeable echo / reverb and a layer of crowd chatter in the background. I need the voice to come through clearly but still sound natural—no metallic artifacts or harsh gating—so the ambience of the location feels present yet unobtrusive. Please work directly on the audio track (or a separated stem) using professional restoration tools such as iZotope RX, Adobe Audition, Reaper with ReaFIR, or comparable software that handles de-reverb and spectral noise reduction gracefully. The goal is to strike a balance between voice intelligibility and the remaining background so the result does not feel artificially “dead.” Deliverables: • Cleaned, fully synced audio file (WAV, 48 kHz, 24-bit) • A version of the vi...

I have a collection of MP3 interview recordings that I need turned into clean, well-structured paragraphs and then examined for who is speaking at every point. Here is what I’m after: • A verbatim or near-verbatim transcription of each interview, formatted in readable paragraphs rather than one long block of text. • Clear speaker identification throughout the transcript so I can easily follow the dialogue and know which participant is talking. Accuracy is critical; the wording must closely match the original audio while still reading smoothly. If you normally use tools such as Audacity, Otter, Descript, or any ASR API, that’s fine—as long as the final transcript is human-checked and the speaker labeling is reliable. Please let me know your approach,...

I’m in Victoria, Australia and ready to take my IRL content to Twitch straight from my phone, but I need a hand making everything run flawlessly. The main focus is the mobile side: installing and configuring Streamlabs Mobile (though I’m open to Streamelements or even Mobily if you know a better workflow), tying it into my Twitch account, and tuning bitrate, resolution, and network settings so the stream stays rock-solid while I’m out on the street. At the same time, I want the broadcast to look professional. That means custom phone-friendly overlays, matching alerts, and a channel banner/offline screen that carry the same style back to my desktop scenes in OBS.

Everything is already installed on my Windows PC—Deep Live Cam, OBS Studio, and the Retrieval-based Voice Conversion WebUI—but the chain still refuses to run smoothly. RVC is the main pain point: models load, yet no converted audio reaches OBS. Deep Live Cam also likes to crash a few seconds into preview, so I probably overlooked a GPU, driver, or virtual-camera tweak. I need you to hop onto the machine through TeamViewer, AnyDesk, or your preferred remote tool, take control, and leave me with a fully functioning pipeline: • Camera feed processed by Deep Live Cam without crashing • Output routed into OBS with the correct scene and virtual camera settings • Live audio passing through RVC and back into OBS in sync with the video Acceptance criteria 1. The ...
