# Audio Ring Modulator Apply ring modulation for a metallic, bell-like sound > Canonical page: https://elysiatools.com/en/tools/audio-ring-modulator - **Category:** Media - **Keywords:** audio, ring modulation, metallic, bell, robotic, sci-fi, electronic, effect ## Overview Creates metallic, bell-like, or robotic sounds by multiplying the input signal with an oscillator. Classic sci-fi effect used for robot voices, metallic textures, and electronic music synthesis. ## Inputs - **Audio File** (file): Select an audio file - **Carrier Frequency (20-20000 Hz)** (number): Frequency of the carrier oscillator. Lower values create slow pulsing, higher values create metallic tones. - **Modulation Depth (0-2.0)** (range): Intensity of the modulation. Higher values create more dramatic metallic effects. - **Carrier Waveform** (select): Shape of the carrier oscillator waveform. Each creates different metallic character. - **Wet/Dry Mix (0-1.0)** (range): Balance between dry (original) and wet (ring modulated) signal. - **Output Format** (select) ## When to use - When you need to generate metallic or bell-like tones for sound effects in films, games, or animations. - For creating robotic voices or sci-fi audio elements in multimedia projects. - In electronic music production to add modulated, synthetic textures to tracks or samples. ## How it works - Upload an audio file in a supported format such as MP3, WAV, or AAC. - Adjust the carrier frequency, modulation depth, and waveform to shape the metallic or robotic character of the sound. - Set the wet/dry mix to balance the ring-modulated effect with the original audio. - Select an output format and process the file to download the modified audio. ## Use cases - Designing robot voice effects for video games or animated characters. - Creating metallic sound textures for film soundtracks or music production. - Synthesizing unique electronic music elements with ring modulation for experimental tracks. ## Frequently asked questions ### What audio file formats can I upload? The tool accepts common audio formats like MP3, WAV, AAC, and others, with a file size limit of 200 MB. ### How does the carrier frequency affect the sound? Lower carrier frequencies (e.g., 20-100 Hz) create slow pulsing effects, while higher frequencies (e.g., 1000-20000 Hz) produce metallic or bell-like tones. ### Can I control how intense the modulation is? Yes, use the Modulation Depth slider from 0 to 2.0; higher values increase the metallic or robotic effect intensity. ### What is the purpose of the wet/dry mix? It blends the original (dry) audio with the ring-modulated (wet) signal, allowing you to dial in the desired effect level from subtle to full processing. ### Which output formats are available? You can choose from MP3, AAC, M4A, OGG Vorbis, Opus, FLAC, and WAV for the processed audio file. ## Related tools - [Audio Vocoder](https://elysiatools.com/en/tools/audio-vocoder): Apply a vocoder effect using a carrier and modulator - [Audio Dither](https://elysiatools.com/en/tools/audio-dither): Apply dithering during bit depth reduction - [FFmpeg Audio Noise Reduction](https://elysiatools.com/en/tools/ffmpeg-audio-noise-reduction): Professional audio noise reduction using FFmpeg advanced filters (highpass, afftdn, loudnorm) for optimal audio cleaning - [Audio Mixer](https://elysiatools.com/en/tools/audio-mixer): Mix two audio files together with customizable timing control - [Audio Speed Changer](https://elysiatools.com/en/tools/audio-speed-changer): Change audio playback speed while maintaining original pitch using time-stretching algorithms - [Audio to Multitrack MIDI (Draft)](https://elysiatools.com/en/tools/audio-to-multitrack-midi): Split a full mix into stems (drums/bass/other/vocals) and transcribe each to MIDI — a multi-track starting point for transcription - [Audio Codec Swap](https://elysiatools.com/en/tools/audio-codec-swap): Change the codec of an audio file within a chosen output format - [Audio Decrackler](https://elysiatools.com/en/tools/audio-decrackle): Remove crackles and subtle impulsive noise from audio files.
