Hello, I can professionally clean your 15-minute MP3 by removing the air conditioner noise while preserving speech clarity as much as possible. I also have experience working with Hindi audio and can identify, transcribe, and report any human voices present in the recording. Here's what I'll deliver: Complete noise reduction to minimize or eliminate the air conditioner sound using professional audio restoration tools. Careful detection of all human voices in Hindi. A report and transcription of the detected Hindi speech, with English translation if required. A high-quality processed audio file with the best possible speech intelligibility. Please note that while modern audio restoration tools can dramatically reduce or remove steady background noise, if voices overlap heavily with the noise, absolute 100% removal without affecting the speech is not always technically possible. My goal is to achieve the cleanest, most natural-sounding result. I'm ready to start immediately and can deliver a fast turnaround. I look forward to working with you.

Air conditioner hum sits in a frequency range that overlaps human speech more than most background noise, so aggressive reduction often thins out the voice itself along with the hum. Careful, targeted removal is what actually gets you complete noise removal without losing voice clarity. How I would approach your file: Profile the air conditioner noise specifically in iZotope RX, applying spectral repair in careful passes rather than one heavy pass that risks dulling the voices. Cross check in Audacity across the full 15 minutes to catch any residual hum or artifacts the first pass missed. Detect and log every instance of human voice in the recording, noting timestamps. Transcribe and translate the Hindi speech accurately, delivering a clean written report alongside the processed audio.

Hi there, I can complete your audio noise reduction and voice detection task. I'll remove the air conditioner background noise from your 15-minute MP3 using professional noise-reduction techniques, then scan the full recording to detect and timestamp any human voice segments, flagging where Hindi speech is present. Delivery: 4 days, revisions included. Clean, noise-free MP3 file -- this is the best option because you get a ready-to-use recording with no manual editing needed on your end, and the same process holds whether your file is 5 minutes or 50. Voice-detection timestamp report -- this is the best option because it lets you jump straight to the relevant segments instead of listening through the whole file. Suggested milestone breakdown (total: $30, 4 days): - M1 - $6 (20%): initial noise-reduction pass, scope confirmed - M2 - $12 (40%): cleaned audio file delivered - M3 - $12 (40%): voice-detection report + final review Fund M1 to start, release when happy, then fund the next. Standard Freelancer escrow -- protects both of us. Ready to begin the moment you award + fund M1. I reply within hours, not days, and I scope every job realistically before bidding, so what I promise is what you get. -- Amr
