Binaural Beats Audio Synthesizer
Generates two sine waves in separate channels: left = carrier frequency, right = carrier + BPM/10 Hz. Each oscillator has amplitude 0.14; the stereo download uses 48 kHz PCM16 WAV.
About this binaural beats audio synthesizer
Binaural Beats Audio Synthesizer — browser-based utility.
How this tool works
Generates two sine waves in separate channels: left = carrier frequency, right = carrier + BPM/10 Hz. Each oscillator has amplitude 0.14; the stereo download uses 48 kHz PCM16 WAV.
- Set the visible controls to: Carrier frequency (Hz) = 440; Beat difference (BPM ÷ 10 Hz) = 120; Duration (seconds) = 3
- Click “Process locally”.
- Download the result and inspect: czoa-binaural-beats-generator.wav — PCM16; 48000 Hz; 2 channels; 144000 frames; 440 / 452 Hz
Worked example
Scenario: Set the visible controls to: Carrier frequency (Hz) = 440; Beat difference (BPM ÷ 10 Hz) = 120; Duration (seconds) = 3 Click “Process locally”. Download the result and inspect: czoa-binaural-beats-generator.wav — PCM16; 48000 Hz; 2 channels; 144000 frames; 440 / 452 Hz
Sample input:
Illustrative output:
Limits and verification
Carrier is 20–20000 Hz, BPM control is 5–400 (a 0.5–40 Hz difference), and duration is 0.2–30 seconds. Headphones keep channels separate; the generator does not establish neurological or health effects.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Binaural Beats Audio Synthesizer process the signal or file?+
Generates two sine waves in separate channels: left = carrier frequency, right = carrier + BPM/10 Hz. Each oscillator has amplitude 0.14; the stereo download uses 48 kHz PCM16 WAV.
How can I reproduce the Binaural Beats Audio Synthesizer example?+
Set the visible controls to: Carrier frequency (Hz) = 440; Beat difference (BPM ÷ 10 Hz) = 120; Duration (seconds) = 3 Click “Process locally”. Download the result and inspect: czoa-binaural-beats-generator.wav — PCM16; 48000 Hz; 2 channels; 144000 frames; 440 / 452 Hz
What limits apply to Binaural Beats Audio Synthesizer?+
Carrier is 20–20000 Hz, BPM control is 5–400 (a 0.5–40 Hz difference), and duration is 0.2–30 seconds. Headphones keep channels separate; the generator does not establish neurological or health effects.
What does browser-isolation evidence establish for Binaural Beats WAV Generator?+
Network requests observed during the example contained no selected-audio payload while the fixture generated and FFmpeg decoded separate 440 Hz and 452 Hz WAV channels. It covers this tested browser value path, not a health effect, an absolute offline claim, or every page-resource and extension environment.
