I have 19 audio files recorded on a voice recorder with an auto-detect feature. The device malfunctioned and recorded continuously, meaning the majority of the files contain blank outdoor background noise (wind rumble, passing cars, and traffic). I need an audio restoration specialist to: 1. Strip out/gate the long stretches of dead background noise to isolate where actual speech occurs. 2. Clean up and enhance the isolated conversations so the dialogue is intelligible and easy to understand. It's approx 38 hours of audio, but it is 90% blank background noise due to an auto-detect malfunction. I need someone to run an automated silence-stripper to pull out the dialogue, and I am only looking to pay for the deep cleanup of the actual spoken sections.

Hello, We can process all 19 audio files by first automatically removing the long sections of background noise and isolating the actual speech. We’ll then focus the detailed restoration work only on the spoken sections, improving clarity, reducing wind and traffic noise, and making the conversations easier to understand. This approach will avoid charging you for unnecessary processing of the large amount of blank audio. Thanks

To strip out/gate the long stretches of dead background noise and enhance the isolated conversations, I would use a combination of manual editing and automated tools to isolate and clean up the actual speech. As an audio restoration expert with skills in Audio Services, Sound Design, Audio Production, and Audio Editing, I can help you achieve your goal of making the dialogue intelligible and easy to understand. I would start by running an automated silence-stripper to pull out the dialogue, then manually clean up and enhance the isolated conversations. Given the 90% blank background noise, I would work efficiently to deliver high-quality results. What is the expected level of background noise presence in the files?

As a professional Sound Engineer specialized in audio restoration, I can recover and clean your dialogues. Here is the technical reality of your project: running an "automated silence-stripper" over 38 hours of wind and traffic noise is highly risky. Automated gates cannot easily distinguish between a passing truck and a quiet voice. If you rely on a fast, automated batch process, you will inevitably lose crucial parts of your conversations. My bid reflects the actual work required to do this safely and professionally: Supervised Extraction: I won't just run a blind script. I will use advanced dynamic gating combined with manual spectral supervision across the 38 hours to isolate the speech (approx. 3-4 hours) without cutting off low-volume syllables. Surgical Restoration: Once isolated, I will use industry-standard spectral repair to separate the voices from the wind rumble and traffic noise, maximizing intelligibility without making the voices sound robotic or heavily distorted. This job requires significant processing power and manual quality control, which is why my rate reflects a premium, detail-oriented service. Please send me a 1-to-2 minute sample of a complex section. I will provide a free restoration test so you can hear the clarity we can achieve before making a decision.

Hi there! I read your project description, and I can definitely help you rescue the dialogue from those 19 audio files. Dealing with a voice recorder malfunction can be frustrating, but since 90% of the 38 hours is just outdoor background noise like wind and traffic, we can efficiently fix this. Here is my workflow for your project: 1. Automated Silence Stripping: I will run an automated gate and strip-silence process to remove all the dead air, wind rumble, and passing cars, completely isolating the actual speech sections as you requested. 2. Deep Audio Cleanup: Once the 10% dialogue is isolated, I will apply surgical EQ, noise reduction, and enhancement processing to make the conversations intelligible, clear, and easy to understand. I use professional audio restoration tools (including Softube plugins) and I am very detail-oriented. Because this is a crucial restoration job, I would love to offer you a FREE 1-to-2-minute test sample. You can send me one of the files, and I'll isolate and clean up a short section so you can hear the quality before you award the project. I will only charge for the deep cleanup of the spoken sections, making my bid highly cost-effective for you. Let me know if you'd like to send over a test file! Best regards, Marie | Budapes studio

Most audio restoration jobs price by total runtime, but the real value here is in isolating the roughly 10% that's actual speech buried inside 38 hours of dead outdoor noise, and pricing that accurately from the start matters more than the total file length suggests. Silence stripping would run first across all 19 files to isolate exactly where speech occurs, cutting through the wind rumble, traffic, and dead air automatically rather than manually scrubbing hours of nothing. Once isolated, the actual dialogue would go through deep cleanup, noise reduction, enhancement, and clarity work, so the spoken sections come out intelligible despite the outdoor recording conditions, with payment scoped to that cleaned speech time rather than the full 38 hours. Is there a rough estimate already of how many total minutes of actual speech exist across the files, or should that be confirmed after the first pass of silence stripping?

Hi, I see you need 19 recordings processed to automatically remove the roughly 90% blank outdoor noise and isolate the actual spoken conversations for deep restoration. I’d suggest using automated silence/noise detection as the first pass, followed by targeted processing only on the extracted speech—carefully reducing wind rumble, traffic, and background noise while preserving natural voices and avoiding robotic artifacts. I have 8+ years of experience in audio editing, restoration, noise reduction, dialogue enhancement, and post-production. My account is new with only 3 reviews, so I’m offering the most reasonable rates to build strong client relationships. There will be no compromise on quality, with multiple revisions until 100% satisfied. I’m available to start immediately and can structure the workflow around the actual spoken duration rather than charging for hours of unusable background recording. Best Regards, DigitalArtForge

Hello, I am a sound engineer; I have carefully read your description and fully understand the issue. My approach is designed specifically for cases like this: 1. Automatic extraction of spoken segments I use professional Voice Activity Detection (VAD) tools and silence/background noise filtering to automatically and precisely remove long stretches of pure noise. This drastically reduces the material requiring processing (from 38 hours down to just the actual dialogue sections). Everything is done locally and efficiently, without uploading your files to the cloud. 2. In-depth cleaning and restoration of the conversations only Once the spoken parts are isolated, I apply a professional audio restoration process: Residual noise reduction (wind, traffic, ambient noise) Improvement of dialogue intelligibility and clarity Voice-oriented equalization, compression, and normalization Removal of artifacts and presence enhancement to ensure the audio is easy to understand I only charge for the actual usable dialogue time remaining after the automatic extraction. You do not pay for processing the full 38 hours of noise. I have experience working with long field recordings, interviews, and problematic voice recorder files. I can handle multi-hour files without issues and deliver the material clean and organized (by file or by conversation segment, as you prefer). Feel free to contact me. Best regards, Reynaldo John Sound Engineer
