How It Works Under the Hood

Web Audio buffer generators synthesize seamless spectral White, Pink, and integrated Brown noise mathematically in RAM, paired with stereo-panned dual sine oscillators separated by exact Hz intervals for binaural entrainment.

2

Choose your brainwave preset (Delta 2Hz, Theta 6Hz, Alpha 10Hz, Beta 18Hz, or Gamma 40Hz).

3

Start the 15/25/45/60-minute deep work timer.

Local Browser Processing & Privacy

Traditional web converters upload your documents, snippets, or media files to remote servers. Binaural Beats & Ambient Focus Noise Generator runs inside your browser tab:

Processed in This Tab

Your input text and files are processed locally without uploading payloads to a processing server.

No Tool Payload Logging

Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).

Tab Memory Lifecycle

Working outputs stay in your browser tab and are released when you reset the tool or close the tab.

Frequently Asked Questions

Do I need headphones for the Binaural Wave slider?

Yes. Binaural beats rely on delivering slightly different frequencies (e.g. 200 Hz left, 210 Hz right) separately to each ear so stereo headphones or earbuds are required for the 10 Hz beat effect.

Does this keep streaming data if I leave the tab open all day?

Zero bytes are streamed after page load — all audio is computed locally inside your browser audio thread.
