# Audio Interview Level Matcher Match loudness between a host and a guest track (or any two voice takes) while preserving natural dynamics. > Canonical page: https://elysiatools.com/en/tools/audio-interview-level-matcher - **Category:** Media - **Keywords:** audio, interview, level matching, loudness, host, guest, dialogue, voice, podcast, normalize ## Overview Measures the integrated LUFS of both tracks, then applies a gentle gain correction plus optional dynamic leveling so the two speakers sit at a consistent loudness — without the over-compressed "radio DJ" sound. Four dynamics-preservation levels: Maximum (pure gain, no compression), High (light leveling), Medium (moderate), Low (aggressive). Use "both → common LUFS" to move both tracks to a shared target, or "B → match A" to keep the host unchanged and only adjust the guest. ## Inputs - **Track A (reference)** (file): Host / reference voice - **Track B (to be matched)** (file): Guest / voice to be matched - **Match Mode** (select) - **Target LUFS** (number) - **Dynamics Preservation** (select) - **Output Format** (select) ## When to use - When editing a podcast interview where the host and guest were recorded on separate microphones with different input levels. - When preparing voiceover tracks or dialogue stems that need to match a specific target LUFS for broadcasting or streaming. - When merging two distinct voice takes into a single audio stream and wanting to avoid sudden jumps in volume. ## How it works - Upload your reference audio file (Track A) and the target audio file (Track B) that needs matching. - Select your match mode, target LUFS level, and choose a dynamics preservation setting to control the level of compression. - The tool analyzes the integrated LUFS of both tracks and applies gain adjustments and leveling to match the volumes. - Download the processed audio files in your preferred output format, such as MP3, WAV, or FLAC. ## Use cases - Balancing host and guest microphone tracks in post-production for a remote podcast episode. - Matching the volume of a guest speaker's voice memo to a studio-recorded host track. - Normalizing dialogue levels across different segments of an audiobook or voiceover project. ## Frequently asked questions ### What is the difference between the match modes? "Both files → common LUFS" adjusts both tracks to a shared target, while "Track B → match Track A" keeps the host track unchanged and only adjusts the guest track. ### Which dynamics preservation setting should I choose? Use "Maximum" for pure gain adjustment with no compression, "High" or "Medium" for light to moderate leveling, and "Low" for aggressive leveling of highly dynamic voices. ### What audio file formats are supported? You can upload any standard audio file, and export the matched tracks in MP3, WAV, FLAC, M4A, or OGG formats. ### Will this tool make my podcast sound over-compressed? No, the tool is designed to preserve natural dynamics, allowing you to avoid the over-compressed "radio DJ" sound by selecting higher dynamics preservation levels. ### What is the recommended target LUFS for podcasts? The default target of -16 LUFS is the industry standard for stereo podcasts and mobile listening. ## Related tools - [Audio Crossfade](https://elysiatools.com/en/tools/audio-crossfade): Apply a crossfade between two audio files - [Duplicate Audio Library Finder](https://elysiatools.com/en/tools/audio-duplicate-library-finder): Find exact and near-duplicate audio across uploaded files or a ZIP, including copies saved with different codecs. - [Audio Groove Quantizer](https://elysiatools.com/en/tools/audio-groove-quantize): Detect loop transients and pull them toward a beat grid, swing template, or a reference audio groove. - [Audio Key Change for Singers](https://elysiatools.com/en/tools/audio-key-change-for-singers): Transpose a song by key or semitones while preserving its duration and speed. - [Audio Mouth Click Finder](https://elysiatools.com/en/tools/audio-mouth-click-finder): Detect-style repair for lip smacks, saliva clicks, mouth ticks, and small voice-over clicks. - [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 Robotize](https://elysiatools.com/en/tools/audio-robotize): Apply a robot voice effect (pitch and bit crush) ## 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.
