I’m upgrading my car’s sound system and want a thoughtfully balanced result—clean detail without losing the fun, chest-hitting output. The plan already includes component speakers up front, coaxials in the rear, and at least one subwoofer for low-end support. What I need now is guidance that ties everything together: • Precise speaker, amplifier, and DSP recommendations that complement those drivers and suit a balanced SQ/SPL approach. • A wiring, crossover, and gain-structure plan that makes the most of available channels and power. • A complete DSP tuning file (or clearly written step-by-step parameters) covering time alignment, EQ, and crossovers so I can load it straight into the unit and audition. Acceptance criteria 1. Bill of materials with b...

I have a set of short song clips (20 in total) that I need turned into polished ringtones. Each finished file must: • run 8–10 seconds • be down-sampled to 8 kHz • exported as WAV • loop smoothly with no click, pop, or timing gap Please normalise the overall level and add a subtle fade-in/out so the loop feels natural. If you know of any other light mastering touches that would enhance a low-bandwidth 8 kHz file without muddying it, let me know—I’m open to ideas. these files are for toys and mainly targetted to childrens. so we need to keep the balance of music and voice. also they will be burnt on an IC so the best output in 8Khz sampling rate is a must I’ll provide the source audio as soon as we start. When you return the mastered WAVs...

I have a completed manuscript that now needs to come alive as an engaging audiobook. Language: italian, english, spanish and french I want a real human voice behind the mic—no synthetic narration—with the flexibility to move naturally between British, American, Italian, and Spanish accents as the text requires. Gender is not important to me; authenticity and clarity are. Your task is to record the entire book, supply clean, professionally mastered audio, and deliver files ready for direct upload to the main audiobook platforms (ACX, Audible, etc.). If you also know reliable AI-based tools that can help with post-production or accent reference, feel free to weave them into your workflow, but the core narration itself has to be your own voice.

I have a collection of short recordings in several European languages and I need each one converted into clean, well-formatted text. Most clips are conversational pieces—think casual interviews, video dialogues and the odd podcast segment—so clear speaker separation and natural punctuation are important. Expect no more than a few hours of material in total; I will send the files in manageable batches along with the language tags (Spanish, French, German or a mix) so you never feel overwhelmed. While this is an entry-level assignment, I still value accuracy: if you are unsure of a word or phrase, simply flag the timestamp and move on—perfection on the first pass is less important than a consistent, readable transcript I can refine later. Deliverables for each file &b...

I need a skilled audio/video editor to minimize heavy background noise to a subtle ambiance and enhance vocal quality so that you can understand for the most part what is being said. I would also like to add accurate subtitles. It's very important that I am able to accurately understand what is being said.

⚠️ Everything has to be finished for the 18th of April. ⚠️ I have an Audacity Macro that I want to copy to Adobe Audition and then improve. It's a macro for speech only audios. You can see a screen capture of the Audacity Macro in the attached files. I will be also be using most of the elements from Izotope Elements Suite 10 in the new macro (RX 11 Elements, Ozone Elements, Nectar Elements). I may want some to add other things like a noise gate, maybe white noise. I'm a beginner at this so I need to be accompanied. ⚠️ Everything has to be finished for the 18th of April. ⚠️

I have Virtual DJ and Djay Pro running smoothly—my mic is live, the main sound is reaching the audience—but I still can’t preview tracks in my Bluetooth headphones before they hit the master output. Because I’m working strictly inside the software with no external controller or mixer, I need someone who knows the internal routing menus, aggregate devices, and audio settings inside both programs to jump in and set this up right away. The goal is simple: cue audio must play exclusively in the headphones while the master keeps streaming as it does now. A short remote session (Zoom, AnyDesk, or similar) that walks me through the exact settings, channel assignments, and any necessary aggregate-device tweaks will be perfect. Acceptance criteria: • Bluetooth h...

I already have several hours of Thai conversational audio that has been passed through an automatic + human transcription process. Before I publish the material, I need a fresh set of ears to listen through each file and make sure every single word in the transcript matches what is actually said. Your core task is simple: correcting the quality of the existing transcript. Where it drifts from the spoken Thai—missing words, wrong particles, mis-heard regional accents—correct it directly in the document. I am not after stylistic rewrites; the goal is a faithful, word-for-word record of the conversations. The rate is : 8 USD/ qualified hour audio

I need a small Python-based utility that runs reliably on macOS and strips the SyntID watermark Google bakes into both its Text-to-Music and Text-to-Speech outputs. The goal is simple: after processing, the resulting audio should pass Google’s own detection checks while sounding identical to the human ear. Here’s what matters most to me: • macOS compatibility out of the box (Monterey and newer) using standard Python 3 libraries plus any open-source audio packages you feel are essential. • One command (or callable function) that accepts a Google-generated audio file, cleans it, and writes back a high-fidelity file in the same format. • Clear inline comments and a concise README so I can understand the logic, install any dependencies with Homebrew/pip, and r...
