# Stereo Signal Tone Generator Generate a stereo test tone file with independent left and right channel frequency, phase, waveform, and level controls. > Canonical page: https://elysiatools.com/en/tools/stereo-signal-tone-generator - **Category:** Media - **Keywords:** stereo, signal, tone, generator, audio, wav, flac, frequency, phase, noise, binaural ## Overview Use this to export calibration tones, dual-mono test files, binaural-beat experiments, and left-right channel checks. White noise ignores the frequency setting for that channel. ## Inputs - **Duration (seconds)** (number): 5 - **Sample Rate** (select) - **Output Format** (select) - **Left Waveform** (select) - **Left Frequency (Hz)** (number): 440 - **Left Phase (degrees)** (number): 0 - **Left Level (%)** (number): 80 - **Right Waveform** (select) - **Right Frequency (Hz)** (number): 440 - **Right Phase (degrees)** (number): 0 - **Right Level (%)** (number): 80 ## When to use - When calibrating studio monitors, headphones, or sound systems to ensure correct left and right channel routing and level balance. - When creating custom binaural beat audio files for acoustic experiments or relaxation by applying slightly different frequencies to each ear. - When testing audio equipment response across different waveforms like sine, square, triangle, or sawtooth at specific sample rates. ## How it works - Select your desired audio duration, sample rate (up to 96 kHz), and output format (WAV or FLAC). - Configure the waveform, frequency, phase offset, and volume level independently for both the left and right channels. - Click generate to synthesize the stereo audio signal and download the resulting high-quality audio file. ## Use cases - Generating a 10-minute binaural beat track using sine waves with a 10 Hz frequency difference between channels. - Creating a quick 5-second channel identification file with a 440 Hz tone on the left and a 1000 Hz tone on the right. - Exporting a phase-inverted test signal by setting one channel's phase to 0 degrees and the other to 180 degrees. ## Frequently asked questions ### What audio formats can I export? You can export your generated stereo tones as 16-bit PCM WAV files or lossless FLAC files. ### How does the noise waveform option handle frequency settings? When you select the Noise waveform for a channel, the frequency setting for that channel is ignored, and white noise is generated instead. ### Can I generate binaural beats with this tool? Yes, by setting slightly different frequencies for the left and right channels (for example, 200 Hz and 208 Hz) using sine waves. ### What is the maximum duration for a generated tone? You can generate stereo audio files with a duration of up to 600 seconds (10 minutes). ### What sample rates are supported? The generator supports standard sample rates of 44.1 kHz, 48 kHz, and high-resolution 96 kHz. ## Related tools - [Batch Audio Converter](https://elysiatools.com/en/tools/audio-batch-converter): Convert multiple audio files between different formats like MP3, WAV, FLAC, AAC, OGG, Opus with quality settings and batch processing - [Audio Codec Swap](https://elysiatools.com/en/tools/audio-codec-swap): Change the codec of an audio file within a chosen output format - [Audio Format Converter](https://elysiatools.com/en/tools/audio-converter): Convert audio files between different formats like MP3, WAV, FLAC, AAC, OGG with quality settings and volume adjustment - [Audio Decrackler](https://elysiatools.com/en/tools/audio-decrackle): Remove crackles and subtle impulsive noise from audio files.
