Why Work With Me? With a deep understanding of both the creative and technical sides of post-production, I bridge the gap between "good audio" and "market-ready content." Whether you are an independent author or a YouTube creator, my goal is to make your content sound (and look) expensive. Core Expertise: ACX & Audiobook Mastering: I precisely calibrate your files to meet all ACX requirements: RMS Levels: Consistent between -23dB and -18dB. Peak Levels: Capped at -3dB. Noise Floor: Crystal clear at -60dB or lower. Formatting: Proper spacing for headers, intros, and outros. Audio Restoration: Professional removal of mouth clicks, plosives (pops), heavy breathing, and background hum using industry-leading tools. Video Editing: Narrative-driven editing for YouTube, social media, and corporate presentations, focusing on pacing and clear audio integration. The Workflow: Cleanup: Stripping away the "room sound" and imperfections. Mastering: Applying EQ, compression, and limiting for that warm, professional "radio" voice. Validation: Running your files through technical benchmarks to ensure 100% compliance. Delivery: Clean, high-quality MP3s or WAVs ready for upload. The Call to Action: Stop worrying about the technical specs and start focusing on your next project. Send me a message today, and let’s discuss how I can make your audio sound flawless.

🏆 Top-Rated Plus Audio Professional | Broadcast-Ready Sound & Commercial Mixing Whether you are a podcaster needing crystal-clear dialogue, an author aiming for flawless ACX approval, or an artist looking for that massive, radio-ready mix—you are in the right place. I am a professional Audio Engineer specializing in transforming raw recordings into polished, studio-quality audio. I handle the technical heavy lifting so you can focus entirely on creating. From surgical noise reduction to adding analog warmth to a sterile digital track, I bridge the gap between "home recording" and "industry standard." 🎙️ Podcast Post-Production & YouTube Audio Keep your audience immersed without the distraction of room echo or volume jumps. ✅ Invisible Editing: Surgical removal of filler words (um, ah), dead air, and unnatural pauses. ✅ Audio Restoration: Advanced noise reduction (removing hum, hiss, and room reverb) using iZotope RX 11. ✅ Broadcast Standards: Multi-track leveling, dynamic EQ, and compression to hit strict LUFS loudness standards. 📚 Audiobook Production (ACX / Audible Guarantee) Pass QA on the very first try. ✅ Technical Compliance: Guaranteed adherence to all ACX and Findaway Voices specs (RMS, Peak, Noise Floor). ✅ Vocal Cleanup: Transparent removal of mouth clicks, heavy breaths, and harsh plosives. ✅ Quality Control: Precise room tone matching, pacing adjustments, and word-by-word proofing. 🎛️ Music Mixing & Mastering You’ve recorded the tracks, but they lack that punch, clarity, and width you hear on Spotify. Let's fix that. ✅ Clarity & Separation: Carving out space for every instrument so there are no muddy frequencies. ✅ Vocal Polish: Professional de-essing, compression, and Pitch Correction (Melodyne / Auto-Tune) so vocals cut through the mix. ✅ Analog Character: Using top-tier emulations (UAD, Tape saturation) to add depth, width, and warmth. ✅ Commercial Loudness: Competitive mastering that sounds massive across all streaming platforms and club speakers without distorting. ⚙️ The Studio & Industry-Standard Toolset Accurate translation is everything. I work out of a dedicated, acoustically treated studio environment to ensure completely accurate monitoring. 🔴 Restoration: iZotope RX 11 Advanced (the gold standard for rescuing noisy audio). 🔴 Analog Dynamics & EQ: Universal Audio (1176, LA-2A, Oxide Tape, Pultec), Softube, and Slate Digital. 🔴 Reverb & Space: Relab LX480, Pulsar W495, Valhalla DSP. 🔴 Software/DAWs: Logic Pro, FL Studio, Adobe Audition, Premiere Pro, Audacity, Descript. 🔴 Hardware: Focusrite Interfaces, Edifier Studio Monitors, Beyerdynamic DT 990 PRO & Audio Technica ATH-M20x reference headphones. 🤝 My Simple Workflow 1. The Demo: Send your raw audio or multi-track stems (WAV format preferred). 2. The Quote: I provide a clear flat rate and strict turnaround time. 3. The Polish: I deliver the first broadcast-ready pass. 4. The Revisions: We tweak the file until it matches your exact vision perfectly. ⭐ See What My Clients Say: "Prashant did an amazing job... his attention to detail and desire to get the ultimate results was first class." "He is attentive and willing to go the extra mile." "A fantastic freelancer who did a very thorough job." Your audio should never sound over-processed or robotic.
