I have three separate one-hour WAV files that were captured on a high-quality recorder. The voices are clear but sit too low in the mix, and a persistent static-like hum is riding underneath. Your task is to bring the spoken content forward, remove or greatly reduce that hum, and return balanced, listener-friendly files. I’d like the finished tracks emailed back to me in the same WAV format unless you recommend a lossless alternative. Acceptance criteria: • Voice levels consistently audible at normal playback volume • Hum or static reduced to the point it is not distracting on headphones • No noticeable artifacts from noise reduction or compression • File length and sync unchanged If you work in tools such as iZotope RX, Adobe Audition, or similar, that’s perfect—as long as the end result meets the criteria above. Feel free to run a short sample by me first if you want confirmation before processing all three hours.

Hi, I'll bring voices forward and remove the static hum from your 3 one-hour WAVs using iZotope RX / Audition — careful de-noise, level balancing, no artifacts, sync and length intact. Delivering balanced, headphone-clean WAVs (or lossless alternative if you prefer). Happy to process a short sample first for your approval.

I understand you need to enhance three one-hour WAV files by elevating the voice levels while effectively reducing the persistent hum. With experience in audio editing using tools like iZotope RX and Adobe Audition, I can ensure the spoken content is clear and listener-friendly. My approach will focus on balancing the voice levels to be consistently audible at normal playback volume, while applying noise reduction techniques to minimize any distracting hum without introducing artifacts. I can maintain the original file length and sync, ensuring a seamless listening experience. If you'd like, I can provide a short sample for your review before processing the complete tracks. Would you prefer to keep the files in WAV format, or are you open to discussing a lossless alternative? Looking forward to your response. Best regards, Junaid
