FAQ
Everything else you wonder
Bilateral sound, privacy, formats and tips for the best experience.
What is bilateral sound and what is it for?
Bilateral stimulation is sound rhythmically moving between the left and right ear. Inspired by EMDR therapies, many people use it to relax, focus and wind down before sleep.
Are my files uploaded to a server?
No. Decoding, previewing and exporting all run in your browser via the Web Audio API. No file ever leaves your device.
Which files can I use?
MP3, WAV, M4A/AAC, OGG and FLAC on most devices. Queue multiple files, batch-process them and download as WAV or MP3.
Can I add a YouTube or Spotify link?
No, you can only upload audio files from your device. Download the track as MP3/WAV first, then upload it.
Is this a therapy tool?
No. Bimeural is a sound experience tool; it does not replace psychotherapy, EMDR treatment or medical care. Consult a professional for trauma, anxiety or sleep disorders.

Which settings should I start with?
Start with 0.5 Hz, 100% depth and the Sine wave — our “Focus” preset. For unwinding try 0.3 Hz Sine (“Relax”); for more pronounced sweeps try 1.0 Hz Triangle (“Deep”).
What is the difference between WAV and MP3?
WAV is lossless but files are large — ideal for archiving and top quality. MP3 (128/192/320 kbps) is much smaller and plenty for everyday phone listening.
Do long files cause problems?
Usually not; processing time scales with length. Just keep the tab open for very long recordings. We cap the queue at 10 files to protect memory.
Can I listen on speakers?
The effect relies on stereo separation; on speakers the channels blend and the sway disappears. Always use stereo headphones.
