I have an MP3 that runs a little over half an hour. Throughout the file there are brief, low-level whispers I need to isolate and make intelligible while keeping the rest of the recording natural-sounding. The goal is a cleaned version in which: • overall background noise is brought down to a moderate level—steady hiss, HVAC hum and handling rustle should sit well below the dialogue; • every whisper is pulled forward enough to be clearly heard without introducing artifacts or pumping; • no information is lost from the original track. A transparent workflow is important to me, so please keep your spectral edits non-destructive and supply both the processed WAV/MP3 and your session or RX/Audition project file when you’re done. If you prefer another DAW, just let me know—those files are fine as long as I can retrace the steps. I’ll consider the job complete once a quick spot-check across several whisper sections shows consistent clarity and the overall noise floor stays even.

Hi, Isolating low-level whispers while keeping the surrounding dialogue natural is a challenge I can easily handle. I work with advanced audio restoration tools and strictly follow a non-destructive workflow. I will ensure: 1 Every whisper is brought forward cleanly with zero pumping or digital artifacts. 2 Background noise (HVAC, hiss, rustle) is pushed well below the dialogue. 3 Your session/project files are delivered alongside the final WAV/MP3 for full transparency. Please feel free to send over a short 1-minute clip of the file. I will gladly provide a free sample of a cleaned-up whisper section so you can test the quality before hiring me. Best, Wahyu

Hi Sasha, I can help with this. I’m an audio engineer experienced with dialogue cleanup, restoration, spectral editing, and making low-level speech more intelligible while keeping the recording natural. For your file, I would approach it carefully rather than just using heavy noise reduction or compression. I’ll first identify the whisper sections, reduce steady background noise such as hiss, HVAC hum, and handling noise, then bring the whispers forward with targeted spectral editing, level automation, EQ, expansion control, and artifact-safe processing. The goal will be improved clarity without making the whole file sound over-processed or unnatural. I can deliver: Cleaned WAV and MP3 versions Session/project file showing the workflow Non-destructive processing where possible Consistent noise floor across the recording A practical honesty check on any sections that are too buried to recover cleanly I also understand that no information should be lost from the original track, so I’ll preserve the source and work transparently so the steps can be reviewed afterward. I can complete this for $150 USD in 2 days. Best, Dirk Androff Audio Engineer / Audio Restoration / Dialogue Cleanup

Hi! I can help with that. I have experience working with low-level dialogue and whisper enhancement using spectral repair and noise reduction while keeping the recording natural-sounding and fully non-destructive. Before confirming the project, could you send me a short fragment that includes one or two of the whisper sections? That way I can test the audio, evaluate how much intelligibility can realistically be recovered, and send you a quick sample so you can decide if you’d like to move forward. If we continue, I can deliver: * cleaned WAV/MP3 files * the editable session/project files (RX, Audition, or compatible DAW session) * a transparent workflow with reversible processing Looking forward to hearing the sample.

Hola, Leí detalladamente los requerimientos para tu archivo de audio y entiendo perfectamente el balance que necesitas: máxima inteligibilidad en los susurros de bajo nivel sin destruir la naturalidad del resto de la grabación. Como ingeniero de sonido especializado en postproducción, este tipo de restauración forense y limpieza espectral es precisamente mi área de experiencia. Si deseas, puedes enviarme una muestra corta de 1 o 2 minutos que contenga alguno de los susurros más complejos y te enviaré una prueba de audio sin costo para que escuches el resultado antes de comenzar. ¡Quedo a tu disposición para empezar a trabajar en tu archivo hoy mismo!

I am a church audio engineer who uses Studio one. I have similar challenges that have overcome specially when only camera audio is working throughout the preaching. Anyway, about our concern, we can pull it off through using 4k SSL G channel strip plugins & other more. Hope my service can be of help to you.
