Holistic Loader's sound healing room lets you design your own sound: play a gong, crystal and Tibetan singing bowls, handpan, tongue drum, wind chimes, harp, sansula, monochord and pan flute, and choose the exact Hz frequency for each instrument yourself — instead of only picking from fixed presets. Click or tap the instruments to play them, no app or sign-up required.
Choose your:
If you're on a mobile: tap an instrument to strike it. Double tap, then hold and sweep, to add more notes or sustain a note (depending on the instrument). On a laptop: click, or double click and drag, to get the same result. Try swiping or dragging across the bowls and the gong to make them sing continuously, or double tap the native flute or sansula to play a melody!
On desktop these live in the fixed panel on the left; on mobile, tap the tabs along the bottom edge to open them.
Press Record to capture your playing, then download it as an audio file once you stop.
A separate tone generator further down the page. Drag the slider anywhere from 20 Hz to 20,000 Hz, pick a waveform and press Play — the scope above shows the waveform live. Handy for exploring one exact frequency on its own.
Four instruments — the gong, the singing bowl, the handpan and the tongue drum — are free to play. The rest, along with the full signal generator and the ability to record & save, unlock with Premium.
















Human hearing spans, at its best, roughly 20 Hz to 20,000 Hz. Start at a low volume, especially with headphones. And one cosmic truth: in real space nothing can be heard at all – sound needs air. These tones stay safely here with you.
