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, a creator seeking professional voiceovers, 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.
🗣️ Professional Voiceover Services
Bring your scripts to life with natural, engaging, and professional vocal performances.
✅ Versatile Delivery: Conversational, authentic, and expressive reads tailored to your specific project needs.
✅ Pristine Studio Quality: All voiceovers are recorded in an acoustically treated studio using professional-grade microphones, ensuring zero background noise.
✅ Full-Service Delivery: You receive files that are fully edited, EQ'd, and broadcast-ready right out of the box.
🎛️ 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, scripts, 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.
