# Audio Reverb Add reverberation to simulate a room or space > Canonical page: https://elysiatools.com/en/tools/audio-reverb - **Category:** Media - **Keywords:** audio, reverb, reverberation, room, space, echo, effect ## Overview Uses multiple delay lines with feedback (aecho) to create realistic room reverberation effects. Simulates different room sizes and acoustic characteristics. ## Inputs - **Audio File** (file): Select an audio file - **Reverb Preset** (select): Choose a preset or use custom settings for full control - **Room Size (0.1-1.0)** (range): Controls the perceived size of the room. Larger values = bigger space. - **Damping (0.1-1.0)** (range): Controls high-frequency absorption. Higher values = more damped sound. - **Reverb Level (0-1.0)** (range): Controls the amount of reverb effect. 0 = dry, 1.0 = fully wet. - **Pre-delay (ms)** (number): Initial delay before reverb starts. Simulates distance to walls. - **Output Format** (select) ## When to use - When you need to add spatial depth and ambiance to dry audio recordings. - To simulate different acoustic environments, such as small rooms or concert halls, for creative effects. - For post-production audio enhancement in media projects like music tracks or podcasts. ## How it works - Upload your audio file in a supported format like MP3 or WAV. - Select a reverb preset (e.g., Small Room, Concert Hall) or customize settings such as room size, damping, and reverb level. - The tool processes the audio using delay lines with feedback to simulate room acoustics based on your inputs. - Download the processed audio in your chosen output format, such as MP3 or FLAC. ## Use cases - Enhancing vocal tracks in music production to add depth and warmth. - Creating immersive sound effects for video games or films by simulating specific environments. - Improving podcast audio by adding subtle room ambiance for a professional studio sound. ## Frequently asked questions ### What audio file formats can I upload? You can upload audio files in common formats like MP3, WAV, AAC, and others, up to 200 MB in size. ### Can I adjust the reverb settings manually? Yes, choose the 'Custom Settings' preset to adjust parameters like room size, damping, wet level, and pre-delay. ### What does the 'wet level' control? Wet level controls the amount of reverb effect applied; 0 is dry (no reverb), and 1.0 is fully wet (all reverb). ### How does pre-delay affect the sound? Pre-delay sets the initial delay before reverb starts, simulating the distance to walls and affecting the perceived space. ### What output formats are available? You can output the processed audio in MP3, AAC, M4A, OGG, Opus, FLAC, or WAV formats. ## Related tools - [Audio Add Chapters](https://elysiatools.com/en/tools/audio-add-chapters): Add chapters to an audio file from a label/chapters file - [Audio Add Silence](https://elysiatools.com/en/tools/audio-add-silence): Add a specified duration of silence to the start or end of an audio file - [Audio Caption Timing Shifter](https://elysiatools.com/en/tools/audio-caption-timing-shifter): Shift SRT or WebVTT captions to a likely speech onset or by a manual offset. - [Audio Fade In](https://elysiatools.com/en/tools/audio-fade-in): Apply a fade-in effect to the beginning of the audio - [Audio Fade Out](https://elysiatools.com/en/tools/audio-fade-out): Apply a fade-out effect to the end of the audio - [Audio Filler Word Removal Map](https://elysiatools.com/en/tools/audio-filler-word-removal-map): Combine a timestamped transcript with the audio to mark filler words (um, uh, 嗯, 那个…) and optionally mute or remove them. - [Seamless Ambience Loop](https://elysiatools.com/en/tools/audio-seamless-ambience-loop): Turn a field recording into one seamless loop for games, meditation apps, or video background beds — quiet-seam placement, long equal-power crossfade, optional high-pass. - [Audio Set Volume](https://elysiatools.com/en/tools/audio-set-volume): Set the volume to a specific level (percent or dB) ## 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 - [Copyright-Free Raw PCM Audio Samples](https://elysiatools.com/en/samples/pcm-samples): Raw PCM s16le audio samples featuring nature ambience and relaxing music for waveform, playback, and conversion workflows ## Related content - [Audio Reverb, Modulation, and Sound Design Effects Tools](https://elysiatools.com/en/hubs/audio-sound-design-effects): Choose, preview, compare, and verify reverb, delay, modulation, and character effects for music, video, podcast, and game sound design.
