# Audio Voice Cleanup Assistant Analyze voice issues and suggest a processing chain, with a before/after preview of the cleaned audio. > Canonical page: https://elysiatools.com/en/tools/audio-voice-cleanup-assistant - **Category:** Media - **Keywords:** audio, voice, cleanup, denoise, de-ess, analyze, podcast, restore ## Overview Decodes your voice to mono PCM, then scans for DC offset, clipping, a high noise floor, low-frequency rumble, mains hum, harsh sibilance and over-compressed dynamics. From those findings it builds a suggested filter chain (high-pass, denoise, de-hum, de-ess, gentle compression, loudness normalization) and renders a cleaned preview so you can hear the difference. The full diagnostic report is returned in metadata. ## Inputs - **Audio File** (file): Select raw voice audio - **Target LUFS** (number) - **True-Peak Limit (dB)** (number) - **Output Format** (select) ## When to use - When you need to quickly diagnose and fix background noise, hums, or harsh sibilance in a podcast or voiceover recording. - When preparing raw voice tracks for distribution and you need to normalize loudness to a specific target LUFS and True-Peak limit. - When you want an automated, intelligent audio restoration chain without manually configuring multiple complex DAW plugins. ## How it works - Upload your raw voice audio file and select your target LUFS, True-Peak limit, and desired output format. - The tool decodes the audio to mono PCM and scans the waveform for DC offset, clipping, low-frequency rumble, mains hum, sibilance, and over-compressed dynamics. - It automatically constructs a custom filter chain (such as high-pass, denoise, de-hum, de-ess, compression, and normalization) based on the detected issues. - The assistant processes the audio and outputs a cleaned preview file along with a detailed diagnostic report in the metadata. ## Use cases - Cleaning up raw podcast voice tracks recorded in untreated rooms with noticeable background hiss or mains hum. - Normalizing voiceover audio to meet standard broadcast or streaming loudness requirements. - Pre-processing voice recordings to remove harsh sibilance and low-frequency rumble before final mixing. ## Frequently asked questions ### What audio formats does the tool support for output? You can export your cleaned audio preview in MP3, WAV, FLAC, M4A, or OGG Vorbis formats. ### How does the tool detect specific voice issues? It decodes the uploaded file to mono PCM and runs diagnostic algorithms to identify DC offset, clipping, noise floor levels, hum frequencies, and sibilance. ### Can I set custom loudness targets for my podcast? Yes, you can adjust the Target LUFS option between -30 and -5 LUFS, and set a True-Peak limit down to -9 dB. ### What is included in the diagnostic report? The report is returned in the output metadata and details the detected levels of noise, clipping, hum, sibilance, and the recommended filter chain. ### Is there a file size limit for the input audio? Yes, the tool supports raw voice audio files up to 100 MB in size. ## Related tools - [Assistive Listening Enhancer](https://elysiatools.com/en/tools/audio-assistive-listening-enhancer): Clarify listening audio with low-frequency cleanup, speech-presence EQ, conservative denoising, and level protection. - [Audio Plosive Reducer](https://elysiatools.com/en/tools/audio-plosive-reducer): Reduce P/B plosive thumps in close-mic speech while preserving voice body. - [Audio Remote Guest Rescue](https://elysiatools.com/en/tools/audio-remote-guest-rescue): Reduce room echo, broadband noise, boxiness, and dullness in remote guest recordings. - [Audio Vocoder](https://elysiatools.com/en/tools/audio-vocoder): Apply a vocoder effect using a carrier and modulator - [Audio Sibilance Map](https://elysiatools.com/en/tools/audio-sibilance-map): Map harsh S, T, and SH regions so de-essing can target the right moments instead of dulling the whole voice. - [Classroom Recording Cleaner](https://elysiatools.com/en/tools/audio-classroom-recording-cleaner): Clean lecture recordings with speech-focused EQ, hum reduction, peak control, and optional long-silence trimming. - [Audio DC Offset Fixer](https://elysiatools.com/en/tools/audio-dc-offset-fixer): Detect and remove DC offset from audio - [Audio Metadata Remover](https://elysiatools.com/en/tools/audio-metadata-remover): Strip technical metadata from an audio file for privacy before sharing ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Speech Learning & Safety Audio Samples](https://elysiatools.com/en/samples/audio-learning-safety-samples): Deterministic synthetic WAV inputs for pronunciation comparison, dictation preflight, alert degradation, and voice privacy tools. ## Related content - [Podcast Recording, Editing, and Delivery](https://elysiatools.com/en/hubs/podcast-recording-editing-delivery): Rescue remote voices, clean speech artifacts, shape the edit, master loudness, add show assets, and validate podcast files before delivery.
